GENERAL DESCRIPTION
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors are
members of the Blackfin family of products, incorporating the
Analog Devices/Intel Micro Signal Architecture (MSA). Blackfin processors combine a dual-MAC state-of-the-art signal
processing engine, the advantages of a clean, orthogonal RISClike microprocessor instruction set, and single instruction, mul­
tiple data (SIMD) multimedia capabilities into a single
instruction set architecture.
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors are
completely code and pin-compatible, differing only with respect
to their performance and on-chip memory. Specific perfor­
mance and memory configurations are shown in Table 1.

SYSTEM INTEGRATION
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors are
highly integrated system-on-a-chip solutions for the next gener­
ation of digital communication and consumer multimedia
applications. By combining industry-standard interfaces with a
high performance signal processing core, users can develop
cost-effective solutions quickly without the need for costly
external components. The system peripherals include a UART
port, an SPI port, two serial ports (SPORTs), four general-pur­
pose timers (three with PWM capability), a real-time clock, a
watchdog timer, and a parallel peripheral interface.

By integrating a rich set of industry-leading system peripherals
and memory, Blackfin processors are the platform of choice for
next generation applications that require RISC-like program­
mability, multimedia support, and leading-edge signal
processing in one integrated package.
PORTABLE LOW POWER ARCHITECTURE
Blackfin processors provide world-class power management
and performance. Blackfin processors are designed in a low
power and low voltage design methodology and feature
dynamic power management—the ability to vary both the volt­
age and frequency of operation to significantly lower overall
Rev. E |
power consumption. Varying the voltage and frequency can
result in a substantial reduction in power consumption, com­
pared with just varying the frequency of operation. This
translates into longer battery life for portable appliances.
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors con­
tain a rich set of peripherals connected to the core via several
high bandwidth buses, providing flexibility in system configura­
tion as well as excellent overall system performance (see the
functional block diagram in Figure 1 on Page 1). The generalpurpose peripherals include functions such as UART, timers
with PWM (pulse-width modulation) and pulse measurement
capability, general-purpose I/O pins, a real-time clock, and a
watchdog timer. This set of functions satisfies a wide variety of
typical system support needs and is augmented by the system
expansion capabilities of the part. In addition to these generalpurpose peripherals, the ADSP-BF531/ADSP-BF532/
ADSP-BF533 processors contain high speed serial and parallel
ports for interfacing to a variety of audio, video, and modem
codec functions; an interrupt controller for flexible manage­
ment 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 sys­
tem to many application scenarios.
All of the peripherals, except for general-purpose I/O, real-time
clock, and timers, are supported by a flexible DMA structure.
There is also a separate memory DMA channel dedicated to
data transfers between the processor’s various memory spaces,
including external SDRAM and asynchronous memory. Multi­
ple on-chip buses running at up to 133 MHz provide enough
bandwidth to keep the processor core running along with activ­
ity on all of the on-chip and external peripherals.
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors
include an on-chip voltage regulator in support of the proces­
sor’s dynamic power management capability. The voltage
regulator provides a range of core voltage levels from a single
2.25 V to 3.6 V input. The voltage regulator can be bypassed at
the user’s discretion.

BLACKFIN PROCESSOR CORE
As shown in Figure 2 on Page 5, 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 compu­
tation units process 8-bit, 16-bit, or 32-bit data from the
register file.
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.
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 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, satu­
ration and rounding, and sign/exponent detection. The set of
video instructions includes byte alignment and packing opera­
tions, 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.
For certain instructions, two 16-bit ALU operations can be per­
formed simultaneously on register pairs (a 16-bit high half and
16-bit low half of a compute register). Quad 16-bit operations
are possible using the second ALU.
The 40-bit shifter can perform shifts and rotates and is used to
support normalization, field extract, and field deposit
instructions.
The program sequencer controls the flow of instruction execu­
tion, 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-over­
head looping. The architecture is fully interlocked, meaning that
the programmer need not manage the pipeline when executing
instructions with data dependencies.
The address arithmetic unit provides two addresses for simulta­
neous 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).
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.
Rev. E |
In addition, multiple L1 memory blocks are provided, offering a
configurable mix of SRAM and cache. The memory manage­
ment unit (MMU) provides memory protection for individual
tasks that may be operating on the core and can protect system
registers from unintended access.
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 instruc­
tions, 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 instruc­
tion 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 syn­
tax 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-BF531/ADSP-BF532/ADSP-BF533 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 4 on Page 6,
Figure 5 on Page 6, and Figure 3 on Page 6.
The L1 memory system is the primary highest performance
memory available to the Blackfin processor. The off-chip mem­
ory system, accessed through the external bus interface unit
(EBIU), provides expansion with SDRAM, flash memory, and
SRAM, optionally accessing up to 132M bytes of
physical memory.
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
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processor has
three blocks of on-chip memory providing high bandwidth
access to the core.
The first is the L1 instruction memory, consisting of up to
80K bytes SRAM, of which 16K bytes can be configured as a
four way set-associative cache. This memory is accessed at full
processor speed.

Figure 2. Blackfin Processor Core
The second on-chip memory block is the L1 data memory, con­
sisting of one or two banks of up to 32K bytes. The memory
banks are configurable, offering both cache and SRAM func­
tionality. This memory block 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 external bus interface unit
(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 128M bytes of SDRAM. The SDRAM con­
troller allows one row to be open for each internal SDRAM
bank, for up to four internal SDRAM banks, improving overall
system 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
Rev. E |
1M byte segment regardless of the size of the devices used, so
that these banks will only be contiguous if each is fully popu­
lated with 1M byte of memory.
I/O Memory Space
Blackfin 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 containing the control MMRs for all core functions,
and the other containing the registers needed for setup and con­
trol of the on-chip peripherals outside of the core. The MMRs
are accessible only in supervisor mode and appear as reserved
space to on-chip peripherals.
Booting
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processor con­
tains a small boot kernel, which configures the appropriate
peripheral for booting. If the ADSP-BF531/ADSP-BF532/
ADSP-BF533 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 14.

DATA BANK B SRAM/CACHE (16K BYTE)
The event controller on the ADSP-BF531/ADSP-BF532/
ADSP-BF533 processor handles all asynchronous and synchro­
nous events to the processor. The ADSP-BF531/ADSP-BF532/
ADSP-BF533 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 prece­
dence 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.
0xFF90 4000
RESERVED
• Reset – This event resets the processor.
0xFF80 8000
DATA BANK A SRAM/CACHE (16K BYTE)
• 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 shut­
down of the system.

• Exceptions – Events that occur synchronously to program
flow (i.e., the exception will be 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.

ADSP-BF531/ADSP-BF532/ADSP-BF533
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 ADSP-BF531/ADSP-BF532/ADSP-BF533 processor event
controller consists of two stages, the core event controller (CEC)
and the system interrupt controller (SIC). The core event con­
troller works with the system interrupt controller to prioritize
and control all system events. 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 inter­
rupts (IVG15–14) are recommended to be reserved for software
interrupt handlers, leaving seven prioritized interrupt inputs to
support the peripherals of the processor. Table 2 describes the
inputs to the CEC, identifies their names in the event vector
table (EVT), and lists their priorities.

Event Control
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processor pro­
vides the user with 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 32 bits wide:
• CEC interrupt latch register (ILAT) – The ILAT register
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 also be written to clear (cancel) latched events. This
register may be read while in supervisor mode and may
only be written while in supervisor mode when the corre­
sponding IMASK bit is cleared.
System Interrupt Controller (SIC)
The system interrupt controller provides the mapping and rout­
ing of events from the many peripheral interrupt sources to the
prioritized general-purpose interrupt inputs of the CEC.
Although the ADSP-BF531/ADSP-BF532/ADSP-BF533 proces­
sor provides a default mapping, the user can alter the mappings
and priorities of interrupt events by writing the appropriate val­
ues into the interrupt assignment registers (SIC_IARx). Table 3
describes the inputs into the SIC and the default mappings into
the CEC.
Rev. E |

• CEC interrupt mask register (IMASK) – The IMASK regis­
ter controls the masking and unmasking of individual
events. When a bit is set in the IMASK register, that event is
unmasked and will be 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.
July 2007
ADSP-BF531/ADSP-BF532/ADSP-BF533
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.
• SIC interrupt mask register (SIC_IMASK) – This register
controls the masking and unmasking of each peripheral
interrupt event. When a bit is set in this register, that
peripheral event is unmasked and will be processed by the
system when asserted. A cleared bit in this register masks
the peripheral event, preventing the processor from servic­
ing the event.
and the asynchronous memory controller. DMA-capable
peripherals include the SPORTs, SPI port, UART, and PPI. Each
individual DMA-capable peripheral has at least one dedicated
DMA channel.
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processor DMA
controller supports both 1-dimensional (1-D) and 2-dimen­
sional (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
de-interleaved on the fly.
Examples of DMA types supported by the ADSP-BF531/
ADSP-BF532/ADSP-BF533 processor DMA controller include:
• A single, linear buffer that stops upon completion
• 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 indi­
cates the peripheral is not asserting the event.
• A circular, autorefreshing buffer that interrupts on each
full or fractionally full buffer
• 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. See Dynamic
Power Management on Page 11.
In addition to the dedicated peripheral DMA channels, there are
two pairs of memory DMA channels provided for transfers
between the various memories of the ADSP-BF531/
ADSP-BF532/ADSP-BF533 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 methodol­
ogy or by a standard register-based autobuffer mechanism.
Because multiple interrupt sources can map to a single generalpurpose interrupt, multiple pulse assertions can occur simulta­
neously, before or during interrupt processing for an interrupt
event already detected on this interrupt input. The IPEND reg­
ister contents are monitored by the SIC as the interrupt
acknowledgement.
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 proces­
sor pipeline. At this point the CEC will recognize and queue 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, depend­
ing on the activity within and the state of the processor.
DMA CONTROLLERS
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processor has
multiple, independent DMA channels 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 DMA-capable peripherals. Addition­
ally, 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

REAL-TIME CLOCK
The processor 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 ADSP-BF531/ADSP-BF532/ADSP-BF533 processor. The
RTC peripheral has dedicated power supply pins so that it can
remain powered up and clocked even when the rest of the pro­
cessor is in a low power state. The RTC provides several
programmable interrupt options, including interrupt per sec­
ond, minute, hour, or day clock ticks, interrupt on
programmable stopwatch countdown, or interrupt at a pro­
grammed 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 a 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. The second alarm is for a day and time of
that day.
Page 8 of 60 |

ADSP-BF531/ADSP-BF532/ADSP-BF533
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 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 a powered-down state.
Connect RTC pins RTXI and RTXO with external components
as shown in Figure 6.

The timer units can be used in conjunction with the UART to
measure the width of the pulses in the data stream to provide an
autobaud detect function for a serial channel.
The timers can generate interrupts to the processor core provid­
ing periodic events for synchronization, either to the system
clock or to a count of external signals.
In addition to the three general-purpose programmable timers,
a fourth timer is also provided. This extra timer is clocked by the
internal processor clock and is typically used as a system tick
clock for generation of operating system periodic interrupts.

internal SCLK.

The ADSP-BF531/ADSP-BF532/ADSP-BF533 processor incor­
porates two dual-channel synchronous serial ports (SPORT0
and SPORT1) for serial and multiprocessor communications.

• I2S capable operation.
• Bidirectional operation – Each SPORT has two sets of inde­
pendent 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.

WATCHDOG TIMER
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processor
includes 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
• 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 bits to 32 bits in length, transferred most-signifi­
cant-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 recommen­
dation 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.
There are four general-purpose programmable timer units in
the ADSP-BF531/ADSP-BF532/ADSP-BF533 processor. Three
timers have an external pin that can be configured either as a
pulse-width modulator (PWM) or timer output, as an input to

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.
• 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 chan­
nels out of a 1,024-channel window and is compatible with
the H.100, H.110, MVIP-90, and HMVIP standards.
The baud rate, serial data format, error code generation and sta­
tus, and interrupts for the UART port are programmable.
The UART programmable features include:
An additional 250 mV of SPORT input hysteresis can be
enabled by setting Bit 15 of the PLL_CTL register. When this bit
is set, all SPORT input pins have the increased hysteresis.
• Supporting bit rates ranging from (fSCLK/1,048,576) bits per
second to (fSCLK/16) bits per second.
• Supporting data formats from seven bits to 12 bits per
frame.
SERIAL PERIPHERAL INTERFACE (SPI) PORT
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processor has 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 input-slave
output, MISO) and a clock pin (serial clock, SCK). An SPI chip
select input pin (SPISS) lets other SPI devices select the proces­
sor, and seven SPI chip select output pins (SPISEL7–1) let the
processor select other SPI devices. The SPI select pins are reconfigured general-purpose I/O pins. Using these pins, the SPI port
provides a full-duplex, synchronous serial interface which sup­
ports both master/slave modes and multimaster environments.
The baud rate and clock phase/polarities for the SPI port are
programmable, and it has an integrated DMA controller, con­
figurable to support transmit or receive data streams. The SPI
DMA controller can only service unidirectional accesses at any
given time.
The SPI port 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.
• 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 UART_Divisor comes from the UART_DLH
register (most significant 8 bits) and UART_DLL register (least
significant 8 bits).
In conjunction with the general-purpose timer functions,
autobaud detection is supported.
The capabilities of the UART are further extended with support
for the Infrared Data Association (IrDA) serial infrared physical
layer link specification (SIR) protocol.
GENERAL-PURPOSE I/O PORT F
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processor has 16
bidirectional, general-purpose I/O pins on Port F (PF15–0).
Each general-purpose I/O pin can be individually controlled by
manipulation of the GPIO control, status and interrupt
registers:
• GPIO direction control register – Specifies the direction of
each individual PFx pin as input or output.
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 sam­
pling of data on the two serial data lines.
UART PORT
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processor pro­
vides a full-duplex universal asynchronous receiver/transmitter
(UART) port, which is fully compatible with PC-standard
UARTs. The UART port provides a simplified UART interface
to other peripherals or hosts, supporting full-duplex, DMA-sup­
ported, asynchronous transfers of serial data. The UART port
includes support for 5 data bits to 8 data bits, 1 stop bit or 2 stop
bits, and none, even, or odd parity. The 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 trans­
fers both transmit and receive data. This reduces the
number and frequency of interrupts required to transfer
Rev. E |

• GPIO control and status registers – The ADSP-BF531/
ADSP-BF532/ADSP-BF533 processor employs 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 GPIO pin values, one register is written in
order to clear GPIO pin values, one register is written in
order to toggle GPIO pin values, and one register is written
in order to specify GPIO pin values. Reading the GPIO sta­
tus register allows software to interrogate the sense of the
GPIO pin.
• GPIO interrupt mask registers – The two GPIO interrupt
mask registers allow each individual PFx pin to function as
an interrupt to the processor. Similar to the two GPIO con­
trol registers that are used to set and clear individual GPIO
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. PFx

ADSP-BF531/ADSP-BF532/ADSP-BF533
pins defined as inputs can be configured to generate hard­
ware interrupts, while output PFx pins can be triggered by
software interrupts.
• GPIO interrupt sensitivity registers – The two GPIO inter­
rupt sensitivity registers specify whether individual PFx
pins are level- or edge-sensitive and specify—if edge-sensi­
tive—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
The processor provides a parallel peripheral interface (PPI) that
can connect directly to parallel A/D and D/A converters, video
encoders and decoders, and other general-purpose peripherals.
The PPI consists of a dedicated input clock pin, up to three
frame synchronization pins, and up to 16 data pins. The input
clock supports parallel data rates up to half the system clock rate
and the synchronization signals can be configured as either
inputs or outputs.
The PPI supports a variety of general-purpose and ITU-R 656
modes of operation. In general-purpose mode, the PPI provides
half-duplex, bi-directional data transfer with up to 16 bits of
data. Up to three frame synchronization signals are also pro­
vided. In ITU-R 656 mode, the PPI provides half-duplex bi­
directional transfer of 8- or 10-bit video data. Additionally, onchip decode of embedded start-of-line (SOL) and start-of-field
(SOF) preamble packets is supported.
General-Purpose Mode Descriptions
The general-purpose modes of the PPI are intended to suit a
wide variety of data capture and transmission applications.
Three distinct submodes are supported:
• Input mode – Frame syncs and data are inputs into the PPI.
• Frame capture mode – Frame syncs are outputs from the
PPI, but data are inputs.
• Output mode – Frame syncs and data are outputs from the
PPI.
Input Mode
Input mode is intended for ADC applications, as well as video
communication with hardware signaling. In its simplest form,
PPI_FS1 is an external frame sync input that controls when to
read data. The PPI_DELAY MMR allows for a delay (in
PPI_CLK cycles) between reception of this frame sync and the
initiation of data reads. The number of input data samples is
user programmable and defined by the contents of the
PPI_COUNT register. The PPI supports 8-bit and 10-bit
through 16-bit data, programmable in the PPI_CONTROL
register.
Rev. E |
Frame Capture Mode
Frame capture mode allows the video source(s) to act as a slave
(e.g., for frame capture). The ADSP-BF531/ADSP-BF532/
ADSP-BF533 processors control when to read from the video
source(s). PPI_FS1 is an HSYNC output and PPI_FS2 is a
VSYNC output.
Output Mode
Output mode is used for transmitting video or other data with
up to three output frame syncs. Typically, a single frame sync is
appropriate for data converter applications, whereas two or
three frame syncs could be used for sending video with hard­
ware signaling.
ITU-R 656 Mode Descriptions
The ITU-R 656 modes of the PPI are intended to suit a wide
variety of video capture, processing, and transmission applica­
tions. Three distinct submodes are supported:
• Active video only mode
• Vertical blanking only mode
• Entire field mode
Active Video Only Mode
Active video only mode is used when only the active video por­
tion of a field is of interest and not any of the blanking intervals.
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. After synchronizing to the start of
Field 1, the PPI ignores incoming samples until it sees an SAV
code. The user specifies the number of active video lines per
frame (in PPI_COUNT register).
Vertical Blanking Interval Mode
In this mode, the PPI only transfers vertical blanking interval
(VBI) data.
Entire Field Mode
In this mode, the entire incoming bit stream is read in through
the PPI. This includes active video, control preamble sequences,
and ancillary data that may be embedded in horizontal and ver­
tical blanking intervals. Data transfer starts immediately after
synchronization to Field 1. Data is transferred to or from the
synchronous channels through eight DMA engines that work
autonomously from the processor core.
DYNAMIC POWER MANAGEMENT
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processor pro­
vides four operating modes, each with a different performance/
power profile. In addition, dynamic power management pro­
vides the control functions to dynamically alter the processor
core supply voltage, further reducing power dissipation. Control
of clocking to each of the processor peripherals also reduces
power consumption. See Table 4 for a summary of the power
settings for each mode.
Page 11 of 60 |
July 2007
ADSP-BF531/ADSP-BF532/ADSP-BF533
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 per­
formance 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
Hibernate State—Maximum Static Power Savings
The hibernate state maximizes static power savings by disabling
the voltage and clocks to the processor core (CCLK) and to all
the synchronous peripherals (SCLK). The internal voltage regu­
lator for the processor can be shut off by writing b#00 to
the FREQ bits of the VR_CTL register. In addition to disabling
the clocks, this sets the internal power supply voltage (VDDINT) to
0 V to provide the lowest static power dissipation. Any critical
information stored internally (memory contents, register con­
tents, etc.) must be written to a nonvolatile storage device prior
to removing power if the processor state is to be preserved.
Since VDDEXT is still supplied in this mode, all of the external pins
three-state, unless otherwise specified. This allows other devices
that may be connected to the processor to still have power
applied without drawing unwanted current. The internal supply
regulator can be woken up either by a real-time clock wakeup or
by asserting the RESET pin.
Power Savings
As shown in Table 5, the ADSP-BF531/ADSP-BF532/
ADSP-BF533 processor supports three different power
domains. The use of multiple power domains maximizes flexi­
bility, 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 man­
agement without affecting the RTC or other I/O devices. There
are no sequencing requirements for the various power domains.
Table 5. Power Domains
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. Typi­
cally an external event or RTC activity will wake up the
processor. When in the sleep mode, assertion of wakeup will
cause the processor to sense the value of the BYPASS bit in the
PLL control register (PLL_CTL). If BYPASS is disabled, the pro­
cessor will transition to the full-on mode. If BYPASS is enabled,
the processor will transition to the active mode.
When in the sleep mode, system DMA access to L1 memory is
not supported.
Deep Sleep Operating Mode—Maximum Dynamic Power
Savings
The deep sleep mode maximizes dynamic power savings by dis­
abling the clocks to the processor core (CCLK) and to all
synchronous peripherals (SCLK). Asynchronous peripherals,
such as the RTC, may still be running but will not be able to
access internal resources or external memory. This powereddown 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 proces­
sor to transition to the full-on mode.

The power dissipated by a processor is largely a function of the
clock frequency of the processor and the square of the operating
voltage. For example, reducing the clock frequency by 25%
results in a 25% reduction in dynamic power dissipation, while
reducing the voltage by 25% reduces dynamic 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.
The dynamic power management feature of the ADSP-BF531/
ADSP-BF532/ADSP-BF533 processor allows both the proces­
sor’s input voltage (VDDINT) and clock frequency (fCCLK) to be
dynamically controlled.
The savings in power dissipation can be modeled using the
power savings factor and % power savings calculations.

ered as noise sources when doing board layout and should not
be routed or placed near sensitive circuits or components on the
board. All internal and I/O power supplies should be well
bypassed with bypass capacitors placed as close to the
ADSP-BF531/ADSP-BF532/ADSP-BF533 processors as
possible.

CLOCK SIGNALS
VOLTAGE REGULATION
The Blackfin processor provides an on-chip voltage regulator
that can generate appropriate VDDINT voltage levels from the
VDDEXT supply. See Operating Conditions on Page 21 for regula­
tor tolerances and acceptable VDDEXT ranges for specific models.
Figure 7 shows the typical external components required to
complete the power management system. The regulator con­
trols 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 (VDDEXT) supplied. While
in the hibernate state, I/O power is still being applied, eliminat­
ing the need for external buffers. The voltage regulator can be
activated from this power-down state either through an RTC
wakeup or by asserting RESET, both of which will then initiate a
boot sequence. The regulator can also be disabled and bypassed
at the user’s discretion.
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processor can be
clocked by an external crystal, a sine wave input, or a buffered,
shaped clock derived from an external clock oscillator.
If an external clock is used, it should be a TTL compatible signal
and must not be halted, changed, or operated below the speci­
fied 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.
Alternatively, because the ADSP-BF531/ADSP-BF532/
ADSP-BF533 processor includes an on-chip oscillator circuit,
an external crystal may be used. For fundamental frequency
operation, use the circuit shown in Figure 8.

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 rec­
ommended. The two capacitors and the series resistor shown in
Figure 8 fine tune the phase and amplitude of the sine

frequency. The capacitor and resistor values shown in Figure 8
are typical values only. The capacitor values are dependent upon
the crystal manufacturer's load capacitance recommendations
and the physical PCB layout. The resistor value depends on the
drive level specified by the crystal manufacturer. System designs
should verify the customized values based on careful investiga­
tion on multiple devices over the allowed temperature range.
A third-overtone crystal can be used at 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 8.
As shown in Figure 9, 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 user programmable 0.5× to 64× multiplica­
tion factor (bounded by specified minimum and maximum
VCO frequencies). The default multiplier is 10×, but it can be
modified by a software instruction sequence. On-the-fly
frequency changes can be effected by simply writing to the
PLL_DIV register.

The core clock (CCLK) frequency can also be dynamically
changed by means of the CSEL1–0 bits of the PLL_DIV register.
Supported CCLK divider ratios are 1, 2, 4, and 8, as shown in
Table 7. This programmable core clock capability is useful for
fast core frequency modifications.

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.
• 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 or 16-bit external flash memory – The flash
boot routine located in boot ROM memory space is set up
using asynchronous Memory Bank 0. All configuration set­
tings are set for the slowest device possible (3-cycle hold
time; 15-cycle R/W access times; 4-cycle setup).
The maximum frequency of the system clock is fSCLK. The divisor
ratio must be chosen to limit the system clock frequency to its
maximum of fSCLK. The SSEL value can be changed dynamically
without any PLL lock latencies by writing the appropriate values

• Boot from SPI serial EEPROM/flash (8-, 16-, or 24-bit
addressable, or Atmel AT45DB041, AT45DB081, or
AT45DB161) – The SPI uses the PF2 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
July 2007
ADSP-BF531/ADSP-BF532/ADSP-BF533
24-bit addressable EEPROM/flash device is detected, and
begins clocking data into the processor at the beginning of
L1 instruction memory.
• Boot from SPI serial master – The Blackfin processor oper­
ates 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 any
more bytes until the flag is deasserted. The GPIO pin is
chosen by the user and this information is transferred to
the Blackfin processor via bits[10:5] of the FLAG header in
the LDR image.
For each of the boot modes, a 10-byte header is first read from
an external memory 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.
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 pro­
vide 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 pro­
grammer 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 com­
piling 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 opera­
tion, allowing multiple levels of access to core processor
resources.
The assembly language, which takes advantage of the proces­
sor’s unique architecture, offers the following advantages:
• Seamlessly integrated DSP/CPU features are optimized for
both 8-bit and 16-bit operations.
• A multi-issue load/store modified Harvard architecture,
which supports two 16-bit MAC or four 8-bit ALU + two
load/store + two pointer updates per cycle.
• 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.
• 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.
DEVELOPMENT TOOLS
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processor is sup­
ported by a complete set of CROSSCORE®† software and
hardware development tools, including Analog Devices emula­
tors and VisualDSP++®‡ development environment. The same
emulator hardware that supports other Blackfin processors also
fully emulates the ADSP-BF531/ADSP-BF532/ADSP-BF533
processor.
The VisualDSP++ project management environment lets pro­
grammers develop and debug an application. This environment
includes an easy to use assembler (which is based on an alge­
braic 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 processor assembly. The processor
has architectural features that improve the efficiency of com­
piled C/C++ code.
The VisualDSP++ debugger has a number of important fea­
tures. Data visualization is enhanced by a plotting package that
offers a significant level of flexibility. This graphical representa­
tion of user data enables the programmer to quickly determine
the performance of an algorithm. As algorithms grow in com­
plexity, 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 pas­
sively gather important code execution metrics without
interrupting the real-time characteristics of the program. Essen­
tially, 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.
Debugging both C/C++ and assembly programs with the
VisualDSP++ debugger, programmers can:
• 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 program­
ming model.
• Insert breakpoints.
• Set conditional breakpoints on registers, memory,
and stacks.

• Perform linear or statistical profiling of program execution.
• Fill, dump, and graphically plot the contents of memory.

Third party software tools include DSP libraries, real-time oper­
ating systems, and block diagram design tools.

• Perform source level debugging.
• Create custom debugger windows.
The VisualDSP++ IDDE lets programmers define and manage
software development. Its dialog boxes and property pages let
programmers configure and manage all of the Blackfin develop­
ment tools, including the color syntax highlighting in the
VisualDSP++ editor. This capability permits 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 mem­
ory and timing constraints of DSP 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 via 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 gen­
eration of various VDK-based objects, and visualizing the
system state, when debugging an application that uses the VDK.
Use the expert linker to visually manipulate the placement of
code and data on the embedded system. View memory utiliza­
tion in a color coded graphical form, easily move code and data
to different areas of the processor or external memory with the
drag of the mouse, and examine runtime stack and heap usage.
The expert linker is fully compatible with existing linker defini­
tion file (LDF), allowing the developer to move between the
graphical and textual environments.
Analog Devices emulators use the IEEE 1149.1 JTAG test access
port of the ADSP-BF531/ADSP-BF532/ADSP-BF533 processor
to monitor and control the target board processor during emu­
lation. The emulator provides full speed emulation, allowing
inspection and modification of memory, registers, and proces­
sor 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.
Analog Devices offers a range of EZ-KIT Lite® evaluation plat­
forms to use as a cost effective method to learn more about
developing or prototyping applications with Analog Devices
processors, platforms, and software tools. Each EZ-KIT Lite
includes an evaluation board along with an evaluation suite of
the VisualDSP++ development and debugging environment
with the C/C++ compiler, assembler, and linker. Also included
are sample application programs, power supply, and a USB
cable. All evaluation versions of the software tools are limited
for use only with the EZ-KIT Lite product.
The USB controller on the EZ-KIT Lite board connects the
board to the USB port of the user’s PC, enabling the Visu­
alDSP++ evaluation suite to emulate the on-board processor incircuit. This permits the customer to download, execute, and
debug programs for the EZ-KIT Lite system. It also allows incircuit programming of the on-board flash device to store userspecific boot code, enabling the board to run as a standalone
unit without being connected to the PC.
With a full version of VisualDSP++ installed (sold separately),
engineers can develop software for the EZ-KIT Lite or any cus­
tom defined system. Connecting one of Analog Devices JTAG
emulators to the EZ-KIT Lite board enables high speed, nonintrusive emulation.
For evaluation of ADSP-BF531/ADSP-BF532/ADSP-BF533
processors, use the EZ-KIT Lite board available from Analog
Devices. Order part number ADDS-BF533-EZLITE. The board
comes with on-chip emulation capabilities and is equipped to
enable software development. Multiple daughter cards are
available.
DESIGNING AN EMULATOR-COMPATIBLE
PROCESSOR BOARD
The Analog Devices family of emulators are tools that every sys­
tem developer needs 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, allow­
ing the developer to load code, set breakpoints, observe
variables, observe memory, and examine registers. The proces­
sor 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.
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.

PIN DESCRIPTIONS
ADSP-BF531/ADSP-BF532/ADSP-BF533 processor pin defini­
tions are listed in Table 9.
All pins are three-stated during and immediately after reset,
except the memory interface, asynchronous memory control,
and synchronous memory control pins, which are driven high.
If BR is active, then the memory pins are also three-stated. All
unused I/O pins have their input buffers disabled with the
exception of the pins that need pull-ups or pull-downs as noted
in the table footnotes.
In order to maintain maximum functionality and reduce pack­
age size and pin count, some pins have dual, multiplexed
functionality. In cases where pin functionality is reconfigurable,
the default state is shown in plain text, while alternate function­
ality is shown in italics.

The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors are 3.3 V tolerant (always accepts up to 3.6 V maximum VIH), but voltage compliance (on outputs, VOH) depends on
the input VDDEXT, because VOH (maximum) approximately equals VDDEXT (maximum). This 3.3 V tolerance applies to bidirectional pins (DATA15–0, TMR2–0, PF15–0, PPI3–0,
RSCLK1–0, TSCLK1–0, RFS1–0, TFS1–0, MOSI, MISO, SCK) and input only pins (BR, ARDY, PPI_CLK, DR0PRI, DR0SEC, DR1PRI, DR1SEC, RX, RTXI, TCK, TDI, TMS,
TRST, CLKIN, RESET, NMI, and BMODE1–0).

Table 12 through Table 15 describe the timing requirements for
the ADSP-BF531/ADSP-BF532/ADSP-BF533 processor clocks.
Take care in selecting MSEL, SSEL, and CSEL ratios so as not to
exceed the maximum core clock and system clock as described
in Absolute Maximum Ratings on Page 23, and the voltage con­
trolled oscillator (VCO) operating frequencies described in
Table 14. Table 14 describes phase-locked loop operating
conditions.

Clock and Reset Timing
Table 16 and Figure 11 describe clock and reset operations. Per
Absolute Maximum Ratings on Page 23, combinations of
CLKIN and clock multipliers/divisors must not result in core/
system clocks exceeding the maximum limits allowed for the
processor, including system clock restrictions related to supply
voltage.

Applies to PLL bypass mode and PLL nonbypass mode.
CLKIN frequency must not change on the fly.
3
Combinations of the CLKIN frequency and the PLL clock multiplier must not exceed the allowed fVCO, fCCLK, and fSCLK settings discussed in Table 12 on Page 24 through
Table 15 on Page 24. Since the default behavior of the PLL is to multiply the CLKIN frequency by 10, the 400 MHz speed grade parts cannot use the full CLKIN period range.
4
If the DF bit in the PLL_CTL register is set, then the maximum tCKIN period is 50 ns.
5
Applies after power-up sequence is complete. At power-up, the processor’s internal phase-locked loop requires no more than 2,000 CLKIN cycles, while RESET is asserted,
assuming stable power supplies and CLKIN (not including start-up time of external clock oscillator).

Universal Asynchronous Receiver-Transmitter
(UART) Port—Receive and Transmit Timing
Figure 26 describes UART port receive and transmit operations.
The maximum baud rate is SCLK/16. As shown in Figure 26
there is some latency between the generation internal UART
interrupts and the external data operations. These latencies are
negligible at the data transmission rates for the UART.

POWER DISSIPATION
Output pins are considered to be disabled when they stop driv­
ing, go into a high impedance state, and start to decay from their
output high or low voltage. The output disable time tDIS is the
difference between tDIS_MEASURED and tDECAY as shown on the left
side of Figure 42.
t DIS = t DIS_MEASURED – t DECAY
The time for the voltage on the bus to decay by ΔV is dependent
on the capacitive load CL and the load current II. This decay time
can be approximated by the equation:
Many operating conditions can affect power dissipation. System
designers should refer to Estimating Power for ADSP-BF531/
BF532/BF533 Blackfin Processors (EE-229) on the Analog
Devices website (www.analog.com)—use site search on
“EE-229.” This document provides detailed information for
optimizing your design for lowest power.
The time tDECAY is calculated with test loads CL and IL, and with
ΔV equal to 0.1 V for VDDEXT (nominal) = 1.8 V or 0.5 V for
VDDEXT (nominal) = 2.5 V/3.3 V.
See the ADSP-BF533 Blackfin Processor Hardware Reference
Manual for definitions of the various operating modes and for
instructions on how to minimize system power.
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.
t DECAY = (C L ΔV) ⁄ I L
TEST CONDITIONS
All timing parameters appearing in this data sheet were mea­
sured under the conditions described in this section. Figure 42
shows the measurement point for ac measurements (except out­
put enable/disable). The measurement point VMEAS is 0.95 V for
VDDEXT (nominal) = 1.8 V or 1.5 V for VDDEXT (nominal) = 2.5 V/
3.3 V.

Figure 43. Output Enable/Disable
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 on the right side of
Figure 43.
The time tENA_MEASURED is the interval, from when the reference signal switches, to when the output voltage reaches VTRIP(high) or
VTRIP (low). For VDDEXT (nominal) = 1.8 V—VTRIP (high) is 1.3 V
and VTRIP (low) is 0.7 V. For VDDEXT (nominal) = 2.5 V/3.3 V—

Example System Hold Time Calculation
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 ADSP-BF531/ADSP-BF532/
ADSP-BF533 processor’s output voltage and the input threshold for the device requiring the hold time. CLis the total bus
capacitance (per data line), and IL is the total leakage or
three-state current (per data line). The hold time will be tDECAY

Capacitive Loading
Output delays and holds are based on standard capacitive loads:
30 pF on all pins (see Figure 44). VLOAD is 0.95 V for VDDEXT
(nominal) = 1.8 V or 1.5 V for VDDEXT (nominal) =
2.5 V/3.3 V. Figure 45 through Figure 56 on Page 48 show how
output rise time varies with capacitance. The delay and hold
specifications given should be derated by a factor derived from
these figures. The graphs in these figures may not be linear out­
side the ranges shown.
