PORTABLE LOW POWER ARCHITECTURE
Blackfin processors provide world-class power management
and performance. They are produced with a low power and low
voltage design methodology and feature on-chip dynamic
power management, which is the ability to vary both the voltage
and frequency of operation to significantly lower overall power
consumption. This capability can result in a substantial reduction in power consumption, compared with just varying the
frequency of operation. This allows longer battery life for
portable appliances.
SYSTEM INTEGRATION
The Blackfin processor is a highly integrated system-on-a-chip
solution for the next generation of embedded network-connected applications. By combining industry-standard interfaces
with a high performance signal processing core, cost-effective
applications can be developed quickly, without the need for
costly external components. The system peripherals include an
IEEE-compliant 802.3 10/100 Ethernet MAC (ADSP-BF536 and
ADSP-BF537 only), a CAN 2.0B controller, a TWI controller,
two UART ports, an SPI port, two serial ports (SPORTs), nine
general-purpose 32-bit timers (eight with PWM capability), a
real-time clock, a watchdog timer, and a parallel peripheral
interface (PPI).
BLACKFIN PROCESSOR PERIPHERALS
The ADSP-BF534/ADSP-BF536/ADSP-BF537 processors contains a rich set of peripherals connected to the core via several
high bandwidth buses, providing flexibility in system configuration as well as excellent overall system performance (see the
block diagram on Page 1). The processors contain dedicated
network communication modules and high speed serial and
parallel ports, an interrupt controller for flexible management
of interrupts from the on-chip peripherals or external sources,
and power management control functions to tailor the performance and power characteristics of the processor and system to
many application scenarios.
All of the peripherals, except for the general-purpose I/O, CAN,
TWI, real-time clock, and timers, are supported by a flexible
DMA structure. There are also separate memory DMA channels
dedicated to data transfers between the processor’s various
memory spaces, including external SDRAM and asynchronous
memory. Multiple on-chip buses running at up to 133 MHz
provide enough bandwidth to keep the processor core running
along with activity on all of the on-chip and external
peripherals.
The Blackfin processors include an on-chip voltage regulator in
support of the processors’ dynamic power management capability. The voltage regulator provides a range of core voltage levels
when supplied from a single 2.25 V to 3.6 V input. The voltage
regulator can be bypassed at the user’s discretion.

ADSP-BF534/ADSP-BF536/ADSP-BF537
BLACKFIN PROCESSOR CORE
instructions include byte alignment and packing operations,
16-bit and 8-bit adds with clipping, 8-bit average operations,
and 8-bit subtract/absolute value/accumulate (SAA) operations.
Also provided are the compare/select and vector search
instructions.
As shown in Figure 2 on Page 4, the Blackfin processor core
contains two 16-bit multipliers, two 40-bit accumulators, two
40-bit ALUs, four video ALUs, and a 40-bit shifter. The computation units process 8-, 16-, or 32-bit data from the register file.
For certain instructions, two 16-bit ALU operations can be performed simultaneously on register pairs (a 16-bit high half and
16-bit low half of a compute register). If the second ALU is used,
quad 16-bit operations are possible.
The compute register file contains eight 32-bit registers. When
performing compute operations on 16-bit operand data, the
register file operates as 16 independent 16-bit registers. All
operands for compute operations come from the multiported
register file and instruction constant fields.
The 40-bit shifter can perform shifts and rotates and is used to
support normalization, field extract, and field deposit
instructions.
Each MAC can perform a 16-bit by 16-bit multiply in each
cycle, accumulating the results into the 40-bit accumulators.
Signed and unsigned formats, rounding, and saturation
are supported.
The program sequencer controls the flow of instruction execution, including instruction alignment and decoding. For
program flow control, the sequencer supports PC relative and
indirect conditional jumps (with static branch prediction), and
subroutine calls. Hardware is provided to support zero-overhead looping. The architecture is fully interlocked, meaning that
the programmer need not manage the pipeline when executing
instructions with data dependencies.
The ALUs perform a traditional set of arithmetic and logical
operations on 16-bit or 32-bit data. In addition, many special
instructions are included to accelerate various signal processing
tasks. These include bit operations such as field extract and population count, modulo 232 multiply, divide primitives, saturation
and rounding, and sign/exponent detection. The set of video

UNIT
ADSP-BF534/ADSP-BF536/ADSP-BF537
The address arithmetic unit provides two addresses for simultaneous dual fetches from memory. It contains a multiported
register file consisting of four sets of 32-bit index, modify,
length, and base registers (for circular buffering), and eight
additional 32-bit pointer registers (for C-style indexed stack
manipulation).
The memory DMA controller provides high bandwidth datamovement capability. It can perform block transfers of code or
data between the internal memory and the external
memory spaces.
Internal (On-Chip) Memory
Blackfin processors support a modified Harvard architecture in
combination with a hierarchical memory structure. Level 1 (L1)
memories are those that typically operate at the full processor
speed with little or no latency. At the L1 level, the instruction
memory holds instructions only. The two data memories hold
data, and a dedicated scratchpad data memory stores stack and
local variable information.
The ADSP-BF534/ADSP-BF536/ADSP-BF537 processors have
three blocks of on-chip memory providing high-bandwidth
access to the core.
In addition, multiple L1 memory blocks are provided, offering a
configurable mix of SRAM and cache. The memory management unit (MMU) provides memory protection for individual
tasks that may be operating on the core and can protect system
registers from unintended access.
The second on-chip memory block is the L1 data memory, consisting of up to two banks of up to 32K bytes each. Each memory
bank is configurable, offering both cache and SRAM functionality. This memory block is accessed at full processor speed.
The architecture provides three modes of operation: user mode,
supervisor mode, and emulation mode. User mode has
restricted access to certain system resources, thus providing a
protected software environment, while supervisor mode has
unrestricted access to the system and core resources.
The Blackfin processor instruction set has been optimized so
that 16-bit opcodes represent the most frequently used instructions, resulting in excellent compiled code density. Complex
DSP instructions are encoded into 32-bit opcodes, representing
fully featured multifunction instructions. Blackfin processors
support a limited multi-issue capability, where a 32-bit instruction can be issued in parallel with two 16-bit instructions,
allowing the programmer to use many of the core resources in a
single instruction cycle.
The Blackfin processor assembly language uses an algebraic syntax for ease of coding and readability. The architecture has been
optimized for use in conjunction with the C/C++ compiler,
resulting in fast and efficient software implementations.
MEMORY ARCHITECTURE
The ADSP-BF534/ADSP-BF536/ADSP-BF537 processors view
memory as a single unified 4G byte address space, using 32-bit
addresses. All resources, including internal memory, external
memory, and I/O control registers, occupy separate sections of
this common address space. The memory portions of this
address space are arranged in a hierarchical structure to provide
a good cost/performance balance of some very fast, low latency
on-chip memory as cache or SRAM, and larger, lower cost, and
performance off-chip memory systems. See Figure 3.
The on-chip L1 memory system is the highest performance
memory available to the Blackfin processor. The off-chip memory system, accessed through the external bus interface unit
(EBIU), provides expansion with SDRAM, flash memory, and
SRAM, optionally accessing up to 516M bytes of
physical memory.
Rev. B
|
The first block is the L1 instruction memory, consisting of
64K bytes SRAM, of which 16K bytes can be configured as a
four-way set-associative cache. This memory is accessed at full
processor speed.
The third memory block is a 4K byte scratchpad SRAM, which
runs at the same speed as the L1 memories, but is only accessible
as data SRAM, and cannot be configured as cache memory.
External (Off-Chip) Memory
External memory is accessed via the EBIU. This 16-bit interface
provides a glueless connection to a bank of synchronous DRAM
(SDRAM) as well as up to four banks of asynchronous memory
devices including flash, EPROM, ROM, SRAM, and memory
mapped I/O devices.
The PC133-compliant SDRAM controller can be programmed
to interface to up to 512M bytes of SDRAM. A separate row can
be open for each SDRAM internal bank, and the SDRAM controller supports up to 4 internal SDRAM banks, improving
overall performance.
The asynchronous memory controller can be programmed to
control up to four banks of devices with very flexible timing
parameters for a wide variety of devices. Each bank occupies a
1M byte segment regardless of the size of the devices used, so
that these banks are only contiguous if each is fully populated
with 1M byte of memory.
I/O Memory Space
The ADSP-BF534/ADSP-BF536/ADSP-BF537 processors do
not define a separate I/O space. All resources are mapped
through the flat 32-bit address space. On-chip I/O devices have
their control registers mapped into memory-mapped registers
(MMRs) at addresses near the top of the 4G byte address space.
These are separated into two smaller blocks, one which contains
the control MMRs for all core functions, and the other which
contains the registers needed for setup and control of the onchip peripherals outside of the core. The MMRs are accessible
only in supervisor mode and appear as reserved space to onchip peripherals.

Booting
The Blackfin processor contains a small on-chip boot kernel,
which configures the appropriate peripheral for booting. If the
Blackfin processor is configured to boot from boot ROM memory space, the processor starts executing from the on-chip boot
ROM. For more information, see Booting Modes on Page 16.
Event Handling
The event controller on the Blackfin processor handles all asynchronous and synchronous events to the processor. The
Blackfin processor provides event handling that supports both
nesting and prioritization. Nesting allows multiple event service
routines to be active simultaneously. Prioritization ensures that
servicing of a higher priority event takes precedence over servicing of a lower priority event. The controller provides support for
five different types of events:
• Emulation – An emulation event causes the processor to
enter emulation mode, allowing command and control of
the processor via the JTAG interface.
• Reset – This event resets the processor.
Rev. B
• Nonmaskable Interrupt (NMI) – The NMI event can be
generated by the software watchdog timer or by the NMI
input signal to the processor. The NMI event is frequently
used as a power-down indicator to initiate an orderly shutdown of the system.
• Exceptions – Events that occur synchronously to program
flow (in other words, the exception is taken before the
instruction is allowed to complete). Conditions such as
data alignment violations and undefined instructions cause
exceptions.
• Interrupts – Events that occur asynchronously to program
flow. They are caused by input pins, timers, and other
peripherals, as well as by an explicit software instruction.
Each event type has an associated register to hold the return
address and an associated return-from-event instruction. When
an event is triggered, the state of the processor is saved on the
supervisor stack.
The Blackfin processor event controller consists of two stages,
the core event controller (CEC) and the system interrupt controller (SIC). The core event controller works with the system
interrupt controller to prioritize and control all system events.
| Page 6 of 68 | July 2006
ADSP-BF534/ADSP-BF536/ADSP-BF537
Conceptually, interrupts from the peripherals enter into the
SIC, and are then routed directly into the general-purpose interrupts of the CEC.
Core Event Controller (CEC)
The CEC supports nine general-purpose interrupts (IVG15–7),
in addition to the dedicated interrupt and exception events. Of
these general-purpose interrupts, the two lowest priority
interrupts (IVG15–14) are recommended to be reserved for
software interrupt handlers, leaving seven prioritized interrupt
inputs to support the peripherals of the Blackfin processor.
Table 2 describes the inputs to the CEC, identifies their names
in the event vector table (EVT), and lists their priorities.

System Interrupt Controller (SIC)
The system interrupt controller provides the mapping and routing of events from the many peripheral interrupt sources to the
prioritized general-purpose interrupt inputs of the CEC.
Although the processor provides a default mapping, the user
can alter the mappings and priorities of interrupt events by writing the appropriate values into the interrupt assignment
registers (IAR). Table 3 describes the inputs into the SIC and the
default mappings into the CEC.

• SIC interrupt wakeup enable register (SIC_IWR) – By
enabling the corresponding bit in this register, a peripheral
can be configured to wake up the processor, should the
core be idled when the event is generated. (For more information, see Dynamic Power Management on Page 13.)
Because multiple interrupt sources can map to a single generalpurpose interrupt, multiple pulse assertions can occur simultaneously, before or during interrupt processing for an interrupt
event already detected on this interrupt input. The IPEND register contents are monitored by the SIC as the interrupt
acknowledgement.
Event Control
The Blackfin processor provides a very flexible mechanism to
control the processing of events. In the CEC, three registers are
used to coordinate and control events. Each register is
16 bits wide:
• CEC interrupt latch register (ILAT) – Indicates when
events have been latched. The appropriate bit is set when
the processor has latched the event and cleared when the
event has been accepted into the system. This register is
updated automatically by the controller, but it may be written only when its corresponding IMASK bit is cleared.
• CEC interrupt mask register (IMASK) – Controls the
masking and unmasking of individual events. When a bit is
set in the IMASK register, that event is unmasked and is
processed by the CEC when asserted. A cleared bit in the
IMASK register masks the event, preventing the processor
from servicing the event even though the event may be
latched in the ILAT register. This register may be read or
written while in supervisor mode. (Note that general-purpose interrupts can be globally enabled and disabled with
the STI and CLI instructions, respectively.)
• CEC interrupt pending register (IPEND) – The IPEND
register keeps track of all nested events. A set bit in the
IPEND register indicates the event is currently active or
nested at some level. This register is updated automatically
by the controller but may be read while in supervisor mode.
The SIC allows further control of event processing by providing
three 32-bit interrupt control and status registers. Each register
contains a bit corresponding to each of the peripheral interrupt
events shown in Table 3 on Page 7.
• SIC interrupt mask register (SIC_IMASK) – Controls the
masking and unmasking of each peripheral interrupt event.
When a bit is set in the register, that peripheral event is
unmasked and is processed by the system when asserted. A
cleared bit in the register masks the peripheral event, preventing the processor from servicing the event.
• SIC interrupt status register (SIC_ISR) – As multiple
peripherals can be mapped to a single event, this register
allows the software to determine which peripheral event
source triggered the interrupt. A set bit indicates the
peripheral is asserting the interrupt, and a cleared bit indicates the peripheral is not asserting the event.
Rev. B
The appropriate ILAT register bit is set when an interrupt rising
edge is detected (detection requires two core clock cycles). The
bit is cleared when the respective IPEND register bit is set. The
IPEND bit indicates that the event has entered into the processor pipeline. At this point the CEC recognizes and queues the
next rising edge event on the corresponding event input. The
minimum latency from the rising edge transition of the generalpurpose interrupt to the IPEND output asserted is three core
clock cycles; however, the latency can be much higher, depending on the activity within and the state of the processor.
DMA CONTROLLERS
The Blackfin processors have multiple, independent DMA controllers that support automated data transfers with minimal
overhead for the processor core. DMA transfers can occur
between the processor’s internal memories and any of its DMAcapable peripherals. Additionally, DMA transfers can be accomplished between any of the DMA-capable peripherals and
external devices connected to the external memory interfaces,
including the SDRAM controller and the asynchronous memory controller. DMA-capable peripherals include the Ethernet
MAC (ADSP-BF536 and ADSP-BF537 only), SPORTs, SPI port,
UARTs, and PPI. Each individual DMA-capable peripheral has
at least one dedicated DMA channel.
The DMA controller supports both one-dimensional (1-D) and
two-dimensional (2-D) DMA transfers. DMA transfer initialization can be implemented from registers or from sets of
parameters called descriptor blocks.
The 2-D DMA capability supports arbitrary row and column
sizes up to 64K elements by 64K elements, and arbitrary row
and column step sizes up to ±32K elements. Furthermore, the
column step size can be less than the row step size, allowing
implementation of interleaved data streams. This feature is
especially useful in video applications where data can be deinterleaved on the fly.
Examples of DMA types supported by the DMA controller
include:
• A single, linear buffer that stops upon completion
• A circular, auto-refreshing buffer that interrupts on each
full or fractionally full buffer
• 1-D or 2-D DMA using a linked list of descriptors
• 2-D DMA using an array of descriptors, specifying only the
base DMA address within a common page.
| Page 8 of 68 | July 2006
ADSP-BF534/ADSP-BF536/ADSP-BF537
In addition to the dedicated peripheral DMA channels, there are
two memory DMA channels provided for transfers between the
various memories of the processor system. This enables transfers of blocks of data between any of the memories—including
external SDRAM, ROM, SRAM, and flash memory—with minimal processor intervention. Memory DMA transfers can be
controlled by a very flexible descriptor-based methodology or
by a standard register-based autobuffer mechanism.
The ADSP-BF534/ADSP-BF536/ADSP-BF537 processors also
have an external DMA controller capability via dual external
DMA request pins when used in conjunction with the external
bus interface unit (EBIU). This functionality can be used when a
high speed interface is required for external FIFOs and high
bandwidth communications peripherals such as USB 2.0. It
allows control of the number of data transfers for memDMA.
The number of transfers per edge is programmable. This feature
can be programmed to allow memDMA to have an increased
priority on the external bus relative to the core.
REAL-TIME CLOCK
The real-time clock (RTC) provides a robust set of digital watch
features, including current time, stopwatch, and alarm. The
RTC is clocked by a 32.768 kHz crystal external to the
processor. The RTC peripheral has dedicated power supply pins
so that it can remain powered up and clocked even when the
rest of the processor is in a low-power state. The RTC provides
several programmable interrupt options, including interrupt
per second, minute, hour, or day clock ticks, interrupt on programmable stopwatch countdown, or interrupt at a
programmed alarm time.
The 32.768 kHz input clock frequency is divided down to a 1 Hz
signal by a prescaler. The counter function of the timer consists
of four counters: a 60-second counter, a 60-minute counter, a
24-hour counter, and an 32,768-day counter.
When enabled, the alarm function generates an interrupt when
the output of the timer matches the programmed value in the
alarm control register. There are two alarms: The first alarm is
for a time of day, while the second alarm is for a day and time of
that day.
The stopwatch function counts down from a programmed
value, with one-second resolution. When the stopwatch is
enabled and the counter underflows, an interrupt is generated.
Like the other peripherals, the RTC can wake up the processor
from sleep mode upon generation of any RTC wakeup event.
Additionally, an RTC wakeup event can wake up the processor
from deep sleep mode, and wake up the on-chip internal voltage
regulator from the hibernate operating mode.
Connect RTC pins RTXI and RTXO with external components
as shown in Figure 4.
WATCHDOG TIMER
The ADSP-BF534/ADSP-BF536/ADSP-BF537 processors
include a 32-bit timer that can be used to implement a software
watchdog function. A software watchdog can improve system
availability by forcing the processor to a known state through
generation of a hardware reset, nonmaskable interrupt (NMI),

or general-purpose interrupt, if the timer expires before being
reset by software. The programmer initializes the count value of
the timer, enables the appropriate interrupt, then enables the
timer. Thereafter, the software must reload the counter before it
counts to zero from the programmed value. This protects the
system from remaining in an unknown state where software,
which would normally reset the timer, has stopped running due
to an external noise condition or software error.
If configured to generate a hardware reset, the watchdog timer
resets both the core and the processor peripherals. After a reset,
software can determine if the watchdog was the source of the
hardware reset by interrogating a status bit in the watchdog
timer control register.
The timer is clocked by the system clock (SCLK), at a maximum
frequency of fSCLK.
TIMERS
There are nine general-purpose programmable timer units in
the processor. Eight timers have an external pin that can be configured either as a pulse width modulator (PWM) or timer
output, as an input to clock the timer, or as a mechanism for
measuring pulse widths and periods of external events. These
timers can be synchronized to an external clock input to the several other associated PF pins, to an external clock input to the
PPI_CLK input pin, or to the internal SCLK.
The timer units can be used in conjunction with the two UARTs
and the CAN controller to measure the width of the pulses in
the data stream to provide a software auto-baud detect function
for the respective serial channels.
The timers can generate interrupts to the processor core providing periodic events for synchronization, either to the system
clock or to a count of external signals.
In addition to the eight general-purpose programmable timers,
a ninth timer is also provided. This extra timer is clocked by the
internal processor clock and is typically used as a system tick
clock for generating periodic interrupts in an operating system.

ADSP-BF534/ADSP-BF536/ADSP-BF537
SERIAL PORTS (SPORTs)
The ADSP-BF534/ADSP-BF536/ADSP-BF537 processors
incorporate two dual-channel synchronous serial ports
(SPORT0 and SPORT1) for serial and multiprocessor communications. The SPORTs support the following features:
• I2S capable operation.
• Bidirectional operation – Each SPORT has two sets of independent transmit and receive pins, enabling eight channels
of I2S stereo audio.
• Buffered (8-deep) transmit and receive ports – Each port
has a data register for transferring data words to and from
other processor components and shift registers for shifting
data in and out of the data registers.
• Clocking – Each transmit and receive port can either use an
external serial clock or generate its own, in frequencies
ranging from (fSCLK/131,070) Hz to (fSCLK/2) Hz.
• Word length – Each SPORT supports serial data words
from 3 to 32 bits in length, transferred most significant bit
first or least significant bit first.
• Framing – Each transmit and receive port can run with or
without frame sync signals for each data word. Frame sync
signals can be generated internally or externally, active high
or low, and with either of two pulse widths and early or late
frame sync.
• Companding in hardware – Each SPORT can perform
A-law or μ-law companding according to ITU recommendation G.711. Companding can be selected on the transmit
and/or receive channel of the SPORT without
additional latencies.
• DMA operations with single-cycle overhead – Each SPORT
can automatically receive and transmit multiple buffers of
memory data. The processor can link or chain sequences of
DMA transfers between a SPORT and memory.
• Interrupts – Each transmit and receive port generates an
interrupt upon completing the transfer of a data word or
after transferring an entire data buffer, or buffers,
through DMA.
• Multichannel capability – Each SPORT supports 128 channels out of a 1024-channel window and is compatible with
the H.100, H.110, MVIP-90, and HMVIP standards.
SERIAL PERIPHERAL INTERFACE (SPI) PORT
The ADSP-BF534/ADSP-BF536/ADSP-BF537 processors have
an SPI-compatible port that enables the processor to communicate with multiple SPI-compatible devices.
The SPI interface uses three pins for transferring data: two data
pins (Master Output-Slave Input, MOSI, and Master InputSlave Output, MISO) and a clock pin (serial clock, SCK). An SPI
chip select input pin (SPISS) lets other SPI devices select the
processor, and seven SPI chip select output pins (SPISEL7–1) let
the processor select other SPI devices. The SPI select pins are
reconfigured programmable flag pins. Using these pins, the SPI
Rev. B
port provides a full-duplex, synchronous serial interface, which
supports both master/slave modes and multimaster
environments.
The SPI port’s baud rate and clock phase/polarities are programmable, and it has an integrated DMA controller,
configurable to support transmit or receive data streams. The
SPI’s DMA controller can only service unidirectional accesses at
any given time.
The SPI port’s clock rate is calculated as:
f SCLK
SPI Clock Rate = -------------------------------2 × SPI_Baud
Where the 16-bit SPI_Baud register contains a value of 2
to 65,535.
During transfers, the SPI port simultaneously transmits and
receives by serially shifting data in and out on its two serial data
lines. The serial clock line synchronizes the shifting and sampling of data on the two serial data lines.
UART PORTS
The ADSP-BF534/ADSP-BF536/ADSP-BF537 processors provide two full-duplex universal asynchronous receiver and
transmitter (UART) ports, which are fully compatible with PCstandard UARTs. Each UART port provides a simplified UART
interface to other peripherals or hosts, supporting full-duplex,
DMA-supported, asynchronous transfers of serial data. A
UART port includes support for five to eight data bits, one or
two stop bits, and none, even, or odd parity. Each UART port
supports two modes of operation:
• PIO (programmed I/O) – The processor sends or receives
data by writing or reading I/O mapped UART registers.
The data is double-buffered on both transmit and receive.
• DMA (direct memory access) – The DMA controller transfers both transmit and receive data. This reduces the
number and frequency of interrupts required to transfer
data to and from memory. The UART has two dedicated
DMA channels, one for transmit and one for receive. These
DMA channels have lower default priority than most DMA
channels because of their relatively low service rates.
Each UART port’s baud rate, serial data format, error code generation and status, and interrupts are programmable:
• Supporting bit rates ranging from (fSCLK/1,048,576) to
(fSCLK/16) bits per second.
• Supporting data formats from 7 to 12 bits per frame.
• Both transmit and receive operations can be configured to
generate maskable interrupts to the processor.
The UART port’s clock rate is calculated as:
f SCLK
UART Clock Rate = ----------------------------------------------16 × UART_Divisor
Where the 16-bit UARTx_Divisor comes from the DLH register
(most significant 8 bits) and UARTx_DLL register (least significant 8 bits).
| Page 10 of 68 | July 2006
ADSP-BF534/ADSP-BF536/ADSP-BF537
In conjunction with the general-purpose timer functions, autobaud detection is supported.
The capabilities of the UARTs are further extended with support for the infrared data association (IrDA) serial infrared
physical layer link specification (SIR) protocol.
CONTROLLER AREA NETWORK (CAN)
The ADSP-BF534/ADSP-BF536/ADSP-BF537 processors offer
a CAN controller that is a communication controller implementing the CAN 2.0B (active) protocol. This protocol is an
asynchronous communications protocol used in both industrial
and automotive control systems. The CAN protocol is wellsuited for control applications due to its capability to communicate reliably over a network, since the protocol incorporates
CRC checking message error tracking, and fault node
confinement.
The CAN controller offers the following features:
• 32 mailboxes (eight receive only, eight transmit only, 16
configurable for receive or transmit).
• Dedicated acceptance masks for each mailbox.
• Additional data filtering on first two bytes.
10/100 ETHERNET MAC
The ADSP-BF536 and ADSP-BF537 processors offer the capability to directly connect to a network by way of an embedded
Fast Ethernet Media Access Controller (MAC) that supports
both 10-BaseT (10M bits/sec) and 100-BaseT (100M bits/sec)
operation. The 10/100 Ethernet MAC peripheral is fully compliant to the IEEE 802.3-2002 standard, and it provides
programmable features designed to minimize supervision, bus
use, or message processing by the rest of the processor system.
Some standard features are:
• Support of MII and RMII protocols for external PHYs.
• Full duplex and half duplex modes.
• Data framing and encapsulation: generation and detection
of preamble, length padding, and FCS.
• Media access management (in half-duplex operation): collision and contention handling, including control of
retransmission of collision frames and of back-off timing.
• Flow control (in full-duplex operation): generation and
detection of PAUSE frames.
• Station management: generation of MDC/MDIO frames
for read-write access to PHY registers.
• Support for both the standard (11-bit) and extended
(29-bit) identifier (ID) message formats.
• Support for remote frames.
• SCLK operating range down to 25 MHz (active and sleep
operating modes).
• Active or passive network support.
• Internal loopback from Tx to Rx.
• CAN wakeup from hibernation mode (lowest static power
consumption mode).
• Interrupts, including: Tx complete, Rx complete, error,
global.
The electrical characteristics of each network connection are
very demanding so the CAN interface is typically divided into
two parts: a controller and a transceiver. This allows a single
controller to support different drivers and CAN networks. The
CAN module represents only the controller part of the interface.
The controller interface supports connection to 3.3 V highspeed, fault-tolerant, single-wire transceivers.
TWI CONTROLLER INTERFACE
The ADSP-BF534/ADSP-BF536/ADSP-BF537 processors
include a 2-wire interface (TWI) module for providing a simple
exchange method of control data between multiple devices. The
TWI is compatible with the widely used I2C® bus standard. The
TWI module offers the capabilities of simultaneous master and
slave operation, support for both 7-bit addressing and multimedia data arbitration. The TWI interface utilizes two pins for
transferring clock (SCL) and data (SDA) and supports the
protocol at speeds up to 400k bits/sec. The TWI interface pins
are compatible with 5 V logic levels.
Additionally, the processor’s TWI module is fully compatible
with serial camera control bus (SCCB) functionality for easier
control of various CMOS camera sensor devices.
Some advanced features are:
• Buffered crystal output to external PHY for support of a
single crystal system.
• Automatic checksum computation of IP header and IP
payload fields of Rx frames.
• Independent 32-bit descriptor-driven Rx and Tx DMA
channels.
• Frame status delivery to memory via DMA, including
frame completion semaphores, for efficient buffer queue
management in software.
• Tx DMA support for separate descriptors for MAC header
and payload to eliminate buffer copy operations.
• Convenient frame alignment modes support even 32-bit
alignment of encapsulated Rx or Tx IP packet data in memory after the 14-byte MAC header.
• Programmable Ethernet event interrupt supports any combination of:
• Any selected Rx or Tx frame status conditions.
• PHY interrupt condition.
• Wakeup frame detected.
• Any selected MAC management counter(s) at
half-full.
• DMA descriptor error.
• 47 MAC management statistics counters with selectable
clear-on-read behavior and programmable interrupts on
half maximum value.
Rev. B
| Page 11 of 68 | July 2006
ADSP-BF534/ADSP-BF536/ADSP-BF537
• Programmable Rx address filters, including a 64-bit
address hash table for multicast and/or unicast frames, and
programmable filter modes for broadcast, multicast, unicast, control, and damaged frames.
• Advanced power management supporting unattended
transfer of Rx and Tx frames and status to/from external
memory via DMA during low-power sleep mode.
• System wakeup from sleep operating mode upon magic
packet or any of four user-definable wakeup frame filters.
• Support for 802.3Q tagged VLAN frames.
• Programmable MDC clock rate and preamble suppression.
• In RMII operation, 7 unused pins may be configured as
GPIO pins for other purposes.
PORTS
The ADSP-BF534/ADSP-BF536/ADSP-BF537 processors
group the many peripheral signals to four ports—Port F, Port G,
Port H, and Port J. Most of the associated pins are shared by
multiple signals. The ports function as multiplexer controls.
Eight of the pins (Port F7–0) offer high source/high sink current
capabilities.
GPIO pins defined as inputs can be configured to generate
hardware interrupts, while output pins can be triggered by
software interrupts.
• GPIO interrupt sensitivity registers – The two GPIO interrupt sensitivity registers specify whether individual pins are
level- or edge-sensitive and specify—if edge-sensitive—
whether just the rising edge or both the rising and falling
edges of the signal are significant. One register selects the
type of sensitivity, and one register selects which edges are
significant for edge-sensitivity.
PARALLEL PERIPHERAL INTERFACE (PPI)
The ADSP-BF534/ADSP-BF536/ADSP-BF537 processors provide a parallel peripheral interface (PPI) that can connect
directly to parallel A/D and D/A converters, ITU-R-601/656
video encoders and decoders, and other general-purpose
peripherals. The PPI consists of a dedicated input clock pin, up
to 3 frame synchronization pins, and up to 16 data pins.
In ITU-R-656 modes, the PPI receives and parses a data stream
of 8-bit or 10-bit data elements. On-chip decode of embedded
preamble control and synchronization information
is supported.
Three distinct ITU-R-656 modes are supported:
General-Purpose I/O (GPIO)
The processors have 48 bidirectional, general-purpose I/O
(GPIO) pins allocated across three separate GPIO modules—
PORTFIO, PORTGIO, and PORTHIO, associated with Port F,
Port G, and Port H, respectively. Port J does not provide GPIO
functionality. Each GPIO-capable pin shares functionality with
other processor peripherals via a multiplexing scheme; however,
the GPIO functionality is the default state of the device upon
power-up. Neither GPIO output or input drivers are active by
default. Each general-purpose port pin can be individually controlled by manipulation of the port control, status, and interrupt
registers:
• GPIO direction control register – Specifies the direction of
each individual GPIO pin as input or output.
• GPIO control and status registers – The processors employ
a “write one to modify” mechanism that allows any combination of individual GPIO pins to be modified in a single
instruction, without affecting the level of any other GPIO
pins. Four control registers are provided. One register is
written in order to set pin values, one register is written in
order to clear pin values, one register is written in order to
toggle pin values, and one register is written in order to
specify a pin value. Reading the GPIO status register allows
software to interrogate the sense of the pins.
• GPIO interrupt mask registers – The two GPIO interrupt
mask registers allow each individual GPIO pin to function
as an interrupt to the processor. Similar to the two GPIO
control registers that are used to set and clear individual
pin values, one GPIO interrupt mask register sets bits to
enable interrupt function, and the other GPIO interrupt
mask register clears bits to disable interrupt function.
• Active video only mode – The PPI does not read in any
data between the End of Active Video (EAV) and Start of
Active Video (SAV) preamble symbols, or any data present
during the vertical blanking intervals. In this mode, the
control byte sequences are not stored to memory; they are
filtered by the PPI.
• Vertical blanking only mode – The PPI only transfers vertical blanking interval (VBI) data, as well as horizontal
blanking information and control byte sequences on
VBI lines.
• Entire field mode – The entire incoming bitstream is read
in through the PPI. This includes active video, control preamble sequences, and ancillary data that may be embedded
in horizontal and vertical blanking intervals.
Though not explicitly supported, ITU-R-656 output functionality can be achieved by setting up the entire frame structure
(including active video, blanking, and control information) in
memory and streaming the data out the PPI in a frame sync-less
mode. The processor’s 2-D DMA features facilitate this transfer
by allowing the static frame buffer (blanking and control codes)
to be placed in memory once, and simply updating the active
video information on a per-frame basis.
The general-purpose modes of the PPI are intended to suit a
wide variety of data capture and transmission applications. The
modes are divided into four main categories, each allowing up
to 16 bits of data transfer per PPI_CLK cycle:
• Data receive with internally generated frame syncs
• Data receive with externally generated frame syncs
• Data transmit with internally generated frame syncs
• Data transmit with externally generated frame syncs
Rev. B
| Page 12 of 68 | July 2006
ADSP-BF534/ADSP-BF536/ADSP-BF537
These modes support ADC/DAC connections, as well as video
communication with hardware signalling. Many of the modes
support more than one level of frame synchronization. If
desired, a programmable delay can be inserted between assertion of a frame sync and reception/transmission of data.
DYNAMIC POWER MANAGEMENT
The ADSP-BF534/ADSP-BF536/ADSP-BF537 processors provide five operating modes, each with a different performance
and power profile. In addition, dynamic power management
provides the control functions to dynamically alter the processor core supply voltage, further reducing power dissipation.
Control of clocking to each of the peripherals also reduces
power consumption. See Table 4 for a summary of the power
settings for each mode.
Full-On Operating Mode—Maximum Performance
In the full-on mode, the PLL is enabled and is not bypassed,
providing capability for maximum operational frequency. This
is the power-up default execution state in which maximum performance can be achieved. The processor core and all enabled
peripherals run at full speed.
Active Operating Mode—Moderate Power Savings
In the active mode, the PLL is enabled but bypassed. Because the
PLL is bypassed, the processor’s core clock (CCLK) and system
clock (SCLK) run at the input clock (CLKIN) frequency. In this
mode, the CLKIN to CCLK multiplier ratio can be changed,
although the changes are not realized until the full-on mode is
entered. DMA access is available to appropriately configured
L1 memories.
In the active mode, it is possible to disable the PLL through the
PLL control register (PLL_CTL). If disabled, the PLL must be
re-enabled before transitioning to the full-on or sleep modes.

Sleep Operating Mode—High Dynamic Power Savings
The sleep mode reduces dynamic power dissipation by disabling
the clock to the processor core (CCLK). The PLL and system
clock (SCLK), however, continue to operate in this mode. Typically an external event or RTC activity wakes up the processor.
When in the sleep mode, asserting wakeup causes the processor
to sense the value of the BYPASS bit in the PLL control register
(PLL_CTL). If BYPASS is disabled, the processor transitions to
the full on mode. If BYPASS is enabled, the processor transitions to the active mode.
Rev. B
System DMA access to L1 memory is not supported in
sleep mode.
Deep Sleep Operating Mode—Maximum Dynamic Power
Savings
The deep sleep mode maximizes dynamic power savings by disabling the clocks to the processor core (CCLK) and to all
synchronous peripherals (SCLK). Asynchronous peripherals,
such as the RTC, may still be running but cannot access internal
resources or external memory. This powered-down mode can
only be exited by assertion of the reset interrupt (RESET) or by
an asynchronous interrupt generated by the RTC. When in deep
sleep mode, an RTC asynchronous interrupt causes the processor to transition to the active mode. Assertion of RESET while
in deep sleep mode causes the processor to transition to the fullon mode.
Hibernate Operating Mode—Maximum Static Power
Savings
The hibernate mode maximizes static power savings by disabling the voltage and clocks to the processor core (CCLK) and
to all of the synchronous peripherals (SCLK). The internal voltage regulator for the processor can be shut off by writing b#00 to
the FREQ bits of the VR_CTL register. This disables both CCLK
and SCLK. Furthermore, it sets the internal power supply voltage (VDDINT) to 0 V to provide the greatest power savings. To
preserve the processor state, prior to removing power, any critical information stored internally (memory contents, register
contents, etc.) must be written to a non volatile storage device.
Since VDDEXT is still supplied in this mode, all of the external pins
three-state, unless otherwise specified. This allows other devices
that are connected to the processor to still have power applied
without drawing unwanted current.
The Ethernet or CAN modules can wake up the internal supply
regulator. The regulator can also be woken up by a real-time
clock wakeup event or by asserting the RESET pin, both of
which initiate the hardware reset sequence.
With the exception of the VR_CTL and the RTC registers, all
internal registers and memories lose their content in the hibernate state. State variables may be held in external SRAM or
SDRAM. The CKELOW bit in the VR_CTL register controls
whether SDRAM operates in self-refresh mode which allows it
to retain its content while the processor is in reset.
Power Savings
As shown in Table 5, the processors support three different
power domains which maximizes flexibility, while maintaining
compliance with industry standards and conventions. By isolating the internal logic of the processor into its own power
domain, separate from the RTC and other I/O, the processor
can take advantage of dynamic power management, without
affecting the RTC or other I/O devices. There are no sequencing
requirements for the various power domains.

The dynamic power management feature allows both the processor’s input voltage (VDDINT) and clock frequency (fCCLK) to be
dynamically controlled.
The power dissipated by a processor is largely a function of its
clock frequency and the square of the operating voltage. For
example, reducing the clock frequency by 25% results in a 25%
reduction in power dissipation, while reducing the voltage by
25% reduces power dissipation by more than 40%. Further,
these power savings are additive, in that if the clock frequency
and supply voltage are both reduced, the power savings can be
dramatic, as shown in the following equations.
The power savings factor is calculated as:

CLOCK SIGNALS
The ADSP-BF534/ADSP-BF536/ADSP-BF537 processor can be
clocked by an external crystal, a sine wave input, or a buffered,
shaped clock derived from an external clock oscillator.
f CCLKRED ⎛ V DDINTRED ⎞ 2 ⎛ T RED ⎞
- × -------------------------- × ------------= -------------------f CCLKNOM ⎝ V DDINTNOM⎠ ⎝ T NOM ⎠
If an external clock is used, it should be a TTL compatible signal
and must not be halted, changed, or operated below the specified frequency during normal operation. This signal is
connected to the processor’s CLKIN pin. When an external
clock is used, the XTAL pin must be left unconnected.
where the variables in the equations are:
fCCLKNOM is the nominal core clock frequency
fCCLKRED is the reduced core clock frequency
Alternatively, because the processors include an on-chip oscillator circuit, an external crystal may be used. For fundamental
frequency operation, use the circuit shown in Figure 6. A
parallel-resonant, fundamental frequency, microprocessorgrade crystal is connected across the CLKIN and XTAL pins.
The on-chip resistance between CLKIN and the XTAL pin is in
the 500 kΩ range. Further parallel resistors are typically not recommended. The two capacitors and the series resistor shown in
Figure 6 fine-tune phase and amplitude of the sine frequency.
VDDINTNOM is the nominal internal supply voltage
VDDINTRED is the reduced internal supply voltage
TNOM is the duration running at fCCLKNOM
TRED is the duration running at fCCLKRED
The percent power savings is calculated as:
% power savings = ( 1 – power savings factor ) × 100%
VOLTAGE REGULATION
The ADSP-BF534/ADSP-BF536/ADSP-BF537 processor provides an on-chip voltage regulator that can generate processor
core voltage levels (0.85 V to 1.2 V guaranteed from –5% to
+10%) from an external 2.25 V to 3.6 V supply. Figure 5 shows
the typical external components required to complete the power
management system. The regulator controls the internal logic
voltage levels and is programmable with the voltage regulator
control register (VR_CTL) in increments of 50 mV. To reduce
standby power consumption, the internal voltage regulator can
be programmed to remove power to the processor core while
keeping I/O power supplied. While in hibernate mode, VDDEXT
can still be applied, eliminating the need for external buffers.
The voltage regulator can be activated from this power-down
state by asserting the RESET pin, which then initiates a boot
sequence. The regulator can also be disabled and bypassed at the
user’s discretion.
Rev. B
The capacitor and resistor values shown in Figure 6 are typical
values only. The capacitor values are dependent upon the crystal
manufacturers’ load capacitance recommendations and the PCB
physical layout. The resistor value depends on the drive level
specified by the crystal manufacturer. The user should verify the
customized values based on careful investigations of multiple
devices over temperature range.
A third-overtone crystal can be used for frequencies above
25 MHz. The circuit is then modified to ensure crystal operation
only at the third overtone, by adding a tuned inductor circuit as
shown in Figure 6. A design procedure for third-overtone operation is discussed in detail in application note EE-168.
The CLKBUF pin is an output pin, and is a buffer version of the
input clock. This pin is particularly useful in Ethernet applications to limit the number of required clock sources in the
system. In this type of application, a single 25 MHz or 50 MHz
crystal may be applied directly to the processors. The 25 MHz or
50 MHz output of CLKBUF can then be connected to an external Ethernet MII or RMII PHY device.

Figure 6. External Crystal Connections
Because of the default 10x PLL multiplier, providing a 50 MHz
CLKIN exceeds the recommended operating conditions of the
lower speed grades. Because of this restriction, a 50 MHz RMII
PHY cannot be clocked directly from the CLKBUF pin. Either
provide a separate 50 MHz clock source, or use an RMII PHY
with 25 MHz clock input options. The CLKBUF output is active
by default and can be disabled using the VR_CTL register for
power savings.
The Blackfin core runs at a different clock rate than the on-chip
peripherals. As shown in Figure 7, the core clock (CCLK) and
system peripheral clock (SCLK) are derived from the input
clock (CLKIN) signal. An on-chip PLL is capable of multiplying
the CLKIN signal by a programmable 0.5× to 64× multiplication
factor (bounded by specified minimum and maximum VCO
frequencies). The default multiplier is 10×, but it can be modified by a software instruction sequence in the PLL_CTL register.
On-the-fly CCLK and SCLK frequency changes can be effected
by simply writing to the PLL_DIV register. Whereas the maximum allowed CCLK and SCLK rates depend on the applied
voltages VDDINT and VDDEXT, the VCO is always permitted to run
up to the frequency specified by the part’s speed grade. The
CLKOUT pin reflects the SCLK frequency to the off-chip world.
It belongs to the SDRAM interface, but it functions as reference
signal in other timing specifications as well. While active by
default, it can be disabled using the EBIU_SDGCTL and
EBIU_AMGCTL registers.
All on-chip peripherals are clocked by the system clock (SCLK).
The system clock frequency is programmable by means of the
SSEL3–0 bits of the PLL_DIV register. The values programmed
into the SSEL fields define a divide ratio between the PLL output
(VCO) and the system clock. SCLK divider values are 1 through
15. Table 6 illustrates typical system clock ratios.

Table 7. This programmable core clock capability is useful for
fast core frequency modifications.

The maximum CCLK frequency not only depends on the part’s
speed grade (see Ordering Guide on Page 66), it also depends on
the applied VDDINT voltage. See Table 12 and Table 13 for details.
The maximal system clock rate (SCLK) depends on the chip
package and the applied VDDEXT voltage (see Table 16).

BOOTING MODES
The ADSP-BF534/ADSP-BF536/ADSP-BF537 processor has six
mechanisms (listed in Table 8) for automatically loading internal and external memory after a reset. A seventh mode is
provided to execute from external memory, bypassing the boot
sequence.

Description

Boot from 8-bit or 16-bit memory
(EPROM/flash)
Reserved
Boot from serial SPI memory (EEPROM/flash)
Boot from SPI host (slave mode)
Boot from serial TWI memory (EEPROM/flash)
Boot from TWI host (slave mode)
Boot from UART host (slave mode)
The BMODE pins of the reset configuration register, sampled
during power-on resets and software-initiated resets, implement the following modes:
• Execute from 16-bit external memory – Execution starts
from address 0x2000 0000 with 16-bit packing. The boot
ROM is bypassed in this mode. All configuration settings
are set for the slowest device possible (3-cycle hold time;
15-cycle R/W access times; 4-cycle setup).
• Boot from 8-bit and 16-bit external flash memory – The
8-bit or 16-bit flash boot routine located in Boot ROM
memory space is set up using asynchronous memory bank
0. All configuration settings are set for the slowest device
possible (3-cycle hold time; 15-cycle R/W access times;
4-cycle setup). The Boot ROM evaluates the first byte of the
boot stream at address 0x2000 0000. If it is 0x40, 8-bit boot
is performed. A 0x60 byte assumes a 16-bit memory device
and performs 8-bit DMA. A 0x20 byte also assumes 16-bit
memory but performs 16-bit DMA.
• Boot from serial SPI memory (EEPROM or flash) – 8-, 16-,
or 24-bit addressable devices are supported as well as
AT45DB041, AT45DB081, AT45DB161, AT45DB321,
AT45DB642, and AT45DB1282 DataFlash® devices from
Atmel. The SPI uses the PF10/SPI SSEL1 output pin to
select a single SPI EEPROM/flash device, submits a read
command and successive address bytes (0x00) until a valid
8-, 16-, or 24-bit, or Atmel addressable device is detected,
and begins clocking data into the processor.
• Boot from SPI host device – The Blackfin processor operates in SPI slave mode and is configured to receive the bytes
of the .LDR file from an SPI host (master) agent. To hold
off the host device from transmitting while the boot ROM
is busy, the Blackfin processor asserts a GPIO pin, called
host wait (HWAIT), to signal the host device not to send
Rev. B
any more bytes until the flag is deasserted. The flag is chosen by the user and this information is transferred to the
Blackfin processor via bits 10:5 of the FLAG header.
• Boot from UART – Using an autobaud handshake
sequence, a boot-stream-formatted program is downloaded
by the host. The host agent selects a baud rate within the
UART’s clocking capabilities. When performing the autobaud, the UART expects an [email protected] (boot stream) character
(8 bits data, 1 start bit, 1 stop bit, no parity bit) on the RXD
pin to determine the bit rate. It then replies with an
acknowledgement that is composed of 4 bytes: 0xBF, the
value of UART_DLL, the value of UART_DLH, and 0x00.
The host can then download the boot stream. When the
processor needs to hold off the host, it deasserts CTS.
Therefore, the host must monitor this signal.
• Boot from serial TWI memory (EEPROM/flash) – The
Blackfin processor operates in master mode and selects the
TWI slave with the unique ID 0xA0. It submits successive
read commands to the memory device starting at two byte
internal address 0x0000 and begins clocking data into the
processor. The TWI memory device should comply with
Philips I2C Bus Specification version 2.1 and have the capability to auto-increment its internal address counter such
that the contents of the memory device can be read
sequentially.
• Boot from TWI host – The TWI host agent selects the slave
with the unique ID 0x5F. The processor replies with an
acknowledgement and the host can then download the
boot stream. The TWI host agent should comply with
Philips I2C Bus Specification version 2.1. An I2C multiplexer can be used to select one processor at a time when
booting multiple processors from a single TWI.
For each of the boot modes, a 10-byte header is first brought in
from an external device. The header specifies the number of
bytes to be transferred and the memory destination address.
Multiple memory blocks may be loaded by any boot sequence.
Once all blocks are loaded, program execution commences from
the start of L1 instruction SRAM.
In addition, Bit 4 of the reset configuration register can be set by
application code to bypass the normal boot sequence during a
software reset. For this case, the processor jumps directly to the
beginning of L1 instruction memory.
To augment the boot modes, a secondary software loader can be
added to provide additional booting mechanisms. This secondary loader could provide the capability to boot from flash,
variable baud rate, and other sources. In all boot modes except
bypass, program execution starts from on-chip L1 memory
address 0xFFA0 0000.
INSTRUCTION SET DESCRIPTION
The Blackfin processor family assembly language instruction set
employs an algebraic syntax designed for ease of coding and
readability. The instructions have been specifically tuned to provide a flexible, densely encoded instruction set that compiles to
a very small final memory size. The instruction set also provides
fully featured multifunction instructions that allow the
| Page 16 of 68 | July 2006
ADSP-BF534/ADSP-BF536/ADSP-BF537
programmer to use many of the processor core resources in a
single instruction. Coupled with many features more often seen
on microcontrollers, this instruction set is very efficient when
compiling C and C++ source code. In addition, the architecture
supports both user (algorithm/application code) and supervisor
(O/S kernel, device drivers, debuggers, ISRs) modes of operation, allowing multiple levels of access to core processor
resources.
The assembly language, which takes advantage of the processor’s unique architecture, offers the following advantages:
• Seamlessly integrated DSP/MCU features are optimized for
both 8-bit and 16-bit operations.
• View mixed C/C++ and assembly code (interleaved source
and object information).
• All registers, I/O, and memory are mapped into a unified
4G byte memory space, providing a simplified programming model.
• Set conditional breakpoints on registers, memory, and
stacks.
• Microcontroller features, such as arbitrary bit and bit-field
manipulation, insertion, and extraction; integer operations
on 8-, 16-, and 32-bit data-types; and separate user and
supervisor stack pointers.
• Perform linear or statistical profiling of program execution.
• Code density enhancements, which include intermixing of
16-bit and 32-bit instructions (no mode switching, no code
segregation). Frequently used instructions are encoded
in 16 bits.
• Create custom debugger windows.
The Blackfin is supported with a complete set of
CROSSCORE®† software and hardware development tools,
including Analog Devices emulators and the VisualDSP++®‡
development environment. The same emulator hardware that
supports other Analog Devices processors also fully emulates
the Blackfin.
The VisualDSP++ project management environment lets programmers develop and debug an application. This environment
includes an easy to use assembler that is based on an algebraic
syntax, an archiver (librarian/library builder), a linker, a loader,
a cycle-accurate instruction-level simulator, a C/C++ compiler,
and a C/C++ runtime library that includes DSP and mathematical functions. A key point for these tools is C/C++ code
efficiency. The compiler has been developed for efficient
translation of C/C++ code to Blackfin assembly. The Blackfin
processor has architectural features that improve the efficiency
of compiled C/C++ code.
The VisualDSP++ debugger has a number of important features. Data visualization is enhanced by a plotting package that
offers a significant level of flexibility. This graphical representation of user data enables the programmer to quickly determine
the performance of an algorithm. As algorithms grow in complexity, this capability can have increasing significance on the

designer’s development schedule, increasing productivity. Statistical profiling enables the programmer to nonintrusively poll
the processor as it is running the program. This feature, unique
to VisualDSP++, enables the software developer to passively
gather important code execution metrics without interrupting
the real-time characteristics of the program. Essentially, the
developer can identify bottlenecks in software quickly and efficiently. By using the profiler, the programmer can focus on
those areas in the program that impact performance and take
corrective action.
• Insert breakpoints.
• Trace instruction execution.
• Fill, dump, and graphically plot the contents of memory.
• Perform source level debugging.
The VisualDSP++ IDE lets programmers define and manage
software development. Its dialog boxes and property pages let
programmers configure and manage all development tools,
including color syntax highlighting in the VisualDSP++ editor.
These capabilities permit programmers to:
• Control how the development tools process inputs and
generate outputs.
• Maintain a one-to-one correspondence with the tool’s
command line switches.
The VisualDSP++ Kernel (VDK) incorporates scheduling and
resource management tailored specifically to address the memory and timing constraints of embedded, real-time
programming. These capabilities enable engineers to develop
code more effectively, eliminating the need to start from the
very beginning when developing new application code. The
VDK features include threads, critical and unscheduled regions,
semaphores, events, and device flags. The VDK also supports
priority-based, pre-emptive, cooperative, and time-sliced scheduling approaches. In addition, the VDK was designed to be
scalable. If the application does not use a specific feature, the
support code for that feature is excluded from the target system.
Because the VDK is a library, a developer can decide whether to
use it or not. The VDK is integrated into the VisualDSP++
development environment, but can also be used with standard
command line tools. When the VDK is used, the development
environment assists the developer with many error prone tasks
and assists in managing system resources, automating the generation of various VDK-based objects, and visualizing the
system state when debugging an application that uses the VDK.

Analog Devices emulators use the IEEE 1149.1 JTAG test access
port of the Blackfin to monitor and control the target board
processor during emulation. The emulator provides full-speed
emulation, allowing inspection and modification of memory,
registers, and processor stacks. Nonintrusive in-circuit emulation is assured by the use of the processor’s JTAG interface—the
emulator does not affect target system loading or timing.
In addition to the software and hardware development tools
available from Analog Devices, third parties provide a wide
range of tools supporting the Blackfin processor family. Third

DESIGNING AN EMULATOR-COMPATIBLE
PROCESSOR BOARD
The Analog Devices family of emulators are tools that every system developer needs in order to test and debug hardware and
software systems. Analog Devices has supplied an IEEE 1149.1
JTAG Test Access Port (TAP) on each JTAG processor. The
emulator uses the TAP to access the internal features of the processor, allowing the developer to load code, set breakpoints,
observe variables, observe memory, and examine registers. The
processor must be halted to send data and commands, but once
an operation has been completed by the emulator, the processor
system is set running at full speed with no impact on
system timing.
To use these emulators, the target board must include a header
that connects the processor’s JTAG port to the emulator.

layout, single processor connections, multiprocessor scan
chains, signal buffering, signal termination, and emulator pod

PIN DESCRIPTIONS
ADSP-BF534/ADSP-BF536/ADSP-BF537 processor’s pin definitions are listed in Table 9. In order to maintain maximum
function and reduce package size and pin count, some pins have
dual, multiplexed functions. In cases where pin function is
reconfigurable, the default state is shown in plain text, while the
alternate function is shown in italics. Pins shown with an asterisk after their name (*) offer high source/high sink current
capabilities.
All pins are three-stated during and immediately after reset,
with the exception of the external memory interface and the
buffered XTAL output pin (CLKBUF). On the external memory
interface, the control and address lines are driven high during
reset unless the BR pin is asserted.
All I/O pins have their input buffers disabled with the exception
of the pins noted in the data sheet that need pull-ups or pulldowns if unused.
The SDA (serial data) and SCL (serial clock) pins are open drain
and therefore require a pull-up resistor. Consult version 2.1 of
the I2C specification for the proper resistor value.

Only one of the listed options can apply to a particular design.
ESD SENSITIVITY
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the Blackfin processor features proprietary ESD protection circuitry, permanent damage may occur
on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.

Universal Asynchronous Receiver-Transmitter
(UART) Ports—Receive and Transmit Timing
Figure 24 describes the UART ports receive and transmit operations. The maximum baud rate is SCLK/16. As shown in
Figure 24 there is some latency between the generation of
internal UART interrupts and the external data operations.
These latencies are negligible at the data transmission rates for
the UART.

The minimum pulse widths apply for TMRx signals in width capture and external clock modes. They also apply to the PF15 or PPI_CLK signals in PWM output mode.
Either a valid setup and hold time or a valid pulse width is sufficient. There is no need to resynchronize programmable flag inputs.

POWER DISSIPATION
Total power dissipation has two components: one due to internal circuitry (PINT) and one due to the switching of external
output drivers (PEXT). Table 40 shows the power dissipation for
internal circuitry (VDDINT).
Many operating conditions can affect power dissipation. System
designers should refer to EE-297: Estimating Power for the
ADSP-BF534/BF536/BF537 Blackfin Processors.” This document
will provide detailed information for optimizing your design for
lowest power.

The external component of total power dissipation is caused by
the switching of output pins. Its magnitude depends on:
• The output capacitance (C0) individual pins have to load.
The frequency f includes driving the load high and then back
low. For example: DATA15–0 pins can drive high and low at a
maximum rate of 1÷(2ⴛtSCLK) while in SDRAM burst mode.
• The maximum frequency (f0) at which individual pins
switch.
A typical power consumption can now be calculated for these
conditions by adding a typical internal power dissipation:
• The output voltage swing (VDDEXT).
Furthermore, because I/O activity is usually not constant over
time, the external component of power dissipation is not a constant value. Its peak value is best estimated by identifying
representative phases with the highest I/O activity and analyzing output switching pin by pin. The following formula
calculates the average power for an analyzed period by accumulating the power of all output pins.
P TOTAL = P EXT + ( I DD × V DDINT )
Note that the conditions causing a worst-case PEXT differ from
those causing a worst-case PINT . Maximum PINT cannot occur
while 100% of the output pins are switching from all ones (1s) to
all zeros (0s). Note, as well, that it is uncommon for an application to have 100% or even 50% of the outputs switching
simultaneously.
P EXT = V DDEXT × ∑ C 0 ⋅ f 0

TEST CONDITIONS
All timing parameters appearing in this data sheet were
measured under the conditions described in this section.
REFERENCE
SIGNAL
Output Enable Time
tDIS_MEASURED
Output pins are considered to be enabled when they have made
a transition from a high impedance state to the point when they
start driving. The output enable time tENA is the interval from
the point when a reference signal reaches a high or low voltage
level to the point when the output starts driving as shown in the
Output Enable/Disable diagram (Figure 47). The time
tENA_MEASURED is the interval from when the reference signal
switches to when the output voltage reaches 2.0 V (output high)
or 1.0 V (output low). Time tTRIP is the interval from when the
output starts driving to when the output reaches the 1.0 V or
2.0 V trip voltage. Time tENA is calculated as shown in
the equation:

Figure 47. Output Enable/Disable
Example System Hold Time Calculation
t ENA = t ENA_MEASURED – t TRIP
If multiple pins (such as the data bus) are enabled, the measurement value is that of the first pin to start driving.
Output Disable Time
Output pins are considered to be disabled when they stop driving, go into a high impedance state, and start to decay from their
output high or low voltage. The time for the voltage on the bus
to decay by ΔV is dependent on the capacitive load, CL and the
load current, IL. This decay time can be approximated by
the equation:
To determine the data output hold time in a particular system,
first calculate tDECAY using the equation given above. Choose ΔV
to be the difference between the processor’s output voltage and
the input threshold for the device requiring the hold time. A
typical ΔV is 0.4 V. CL is the total bus capacitance (per data line),
and IL is the total leakage or three-state current (per data line).
The hold time is tDECAY plus the minimum disable time (for
example, tDSDAT for an SDRAM write cycle).

The output disable time tDIS is the difference between
tDIS_MEASURED and tDECAY as shown in Figure 47. The time
tDIS_MEASURED is the interval from when the reference signal
switches to when the output voltage decays ΔV from the measured output-high or output-low voltage. The time tDECAY is
calculated with test loads CL and IL, and with ΔV equal to 0.5 V.
