GENERAL DESCRIPTION
The ADSP-2136x SHARC® processor is a member of the SIMD
SHARC family of DSPs that feature Analog Devices, Inc., Super
Harvard Architecture. The processor is source code-compatible
with the ADSP-2126x and ADSP-2116x DSPs, as well as with
first generation ADSP-2106x SHARC processors in SISD
(single-instruction, single-data) mode. The ADSP-2136x are
32-/40-bit floating-point processors optimized for high
performance automotive audio applications. They contain a
large on-chip SRAM and ROM, multiple internal buses to eliminate I/O bottlenecks, and an innovative digital audio interface
(DAI).

SHARC FAMILY CORE ARCHITECTURE
Entering SIMD mode also has an effect on the way data is transferred between memory and the processing elements. When in
SIMD mode, twice the data bandwidth is required to sustain
computational operation in the processing elements. Because of
this requirement, entering SIMD mode also doubles the
bandwidth between memory and the processing elements.
When using the DAGs to transfer data in SIMD mode, two data
values are transferred with each access of memory or
the register file.
The ADSP-2136x is code-compatible at the assembly level with
the ADSP-2126x, ADSP-21160, and ADSP-21161, and with the
first generation ADSP-2106x SHARC processors. The
ADSP-2136x shares architectural features with the ADSP-2126x
and ADSP-2116x SIMD SHARC processors, as shown in
Figure 2 and detailed in the following sections.
SIMD Computational Engine
The processor contains two computational processing elements
that operate as a single-instruction, multiple-data (SIMD)
engine. The processing elements are referred to as PEX and PEY
and each contains an ALU, multiplier, shifter, and register file.
PEX is always active, and PEY can be enabled by setting the
PEYEN mode bit in the MODE1 register. When this mode is
enabled, the same instruction is executed in both processing elements, but each processing element operates on different data.
This architecture is efficient at executing math intensive signal
processing algorithms.
S
FLAG
JTAG
Independent, Parallel Computation Units
Within each processing element is a set of computational units.
The computational units consist of an arithmetic/logic unit
(ALU), multiplier, and shifter. These units perform all operations in a single cycle. The three units within each processing
element are arranged in parallel, maximizing computational
throughput. Single multifunction instructions execute parallel
ALU and multiplier operations. In SIMD mode, the parallel
ALU and multiplier operations occur in both processing
elements. These computation units support IEEE 32-bit,
single-precision floating-point, 40-bit extended-precision
floating-point, and 32-bit fixed-point data formats.

Data Register File
Each processing element contains a general-purpose data register file. The register files transfer data between the computation
units and the data buses, and store intermediate results. These
10-port, 32-register (16 primary, 16 secondary) files, combined
with the ADSP-2136x enhanced Harvard architecture, allow
unconstrained data flow between computation units and internal memory. The registers in PEX are referred to as R0–R15 and
in PEY as S0–S15.
Context switch
Many of the processor’s registers have secondary registers that
can be activated during interrupt servicing for a fast context
switch. The data registers in the register file, the DAG registers,
and the multiplier result register all have secondary registers.
The primary registers are active at reset, while the secondary
registers are activated by control bits in a mode control register.
Universal Registers
The universal registers are general purpose registers. The
USTAT (4) registers allow easy bit manipulations (Set, Clear,
Toggle, Test, XOR) for all system registers (control/status) of
the core.
The data bus exchange register (PX) permits data to be passed
between the 64-bit PM data bus and the 64-bit DM data bus, or
between the 40-bit register file and the PM/DM data bus. These
registers contain hardware to handle the data width difference.
Timer
A core timer that can generate periodic software interrupts. The
core timer can be configured to use FLAG3 as a timer expired
signal.
Single-Cycle Fetch of Instruction and Four Operands
The processor features an enhanced Harvard architecture in
which the data memory (DM) bus transfers data and the program memory (PM) bus transfers both instructions and data
(see Figure 2). With the its separate program and data memory
buses and on-chip instruction cache, the processor can simultaneously fetch four operands (two over each data bus) and one
instruction (from the cache), all in a single cycle.
Instruction Cache
The processor includes an on-chip instruction cache that
enables three-bus operation for fetching an instruction and four
data values. The cache is selective—only the instructions whose
fetches conflict with PM bus data accesses are cached. This
cache allows full-speed execution of core looped operations
such as digital filter multiply-accumulates, and FFT butterfly
processing.
Data Address Generators with Zero-Overhead Hardware
Circular Buffer Support
The processor’s two data address generators (DAGs) are used
for indirect addressing and implementing circular data buffers
in hardware. Circular buffers allow efficient programming of
delay lines and other data structures required in digital signal

processing, and are commonly used in digital filters and Fourier
transforms. The two DAGs contain sufficient registers to allow
the creation of up to 32 circular buffers (16 primary register sets,
16 secondary). The DAGs automatically handle address pointer
wraparound, reduce overhead, increase performance, and simplify implementation. Circular buffers can start and end at any
memory location.
Flexible Instruction Set
The 48-bit instruction word accommodates a variety of parallel
operations for concise programming. For example, the
processor can conditionally execute a multiply, an add, and a
subtract in both processing elements while branching and fetching up to four 32-bit values from memory—all in a single
instruction.
On-Chip Memory
The processor contains 3M bits of internal SRAM and 4M bits
of internal ROM. Each block can be configured for different
combinations of code and data storage (see Table 3). Each
memory block supports single-cycle, independent accesses by
the core processor and I/O processor. The processor’s memory
architecture, in combination with its separate on-chip buses,
allows two data transfers from the core and one from the I/O
processor, in a single cycle.
The SRAM can be configured as a maximum of 96K words of
32-bit data, 192K words of 16-bit data, 64K words of 48-bit
instructions (or 40-bit data), or combinations of different word
sizes up to 3M bits. All of the memory can be accessed as 16-bit,
32-bit, 48-bit, or 64-bit words. A 16-bit floating-point storage
format is supported that effectively doubles the amount of data
that can be stored on-chip. Conversion between the 32-bit
floating-point and 16-bit floating-point formats is performed in
a single instruction. While each memory block can store combinations of code and data, accesses are most efficient when one
block stores data using the DM bus for transfers, and the other
block stores instructions and data using the PM bus for
transfers.
Using the DM bus and PM buses, with one bus dedicated to
each memory block, assures single-cycle execution with two
data transfers. In this case, the instruction must be available in
the cache.
On-Chip Memory Bandwidth
The internal memory architecture allows three accesses at the
same time to any of the four blocks, assuming no block conflicts. The total bandwidth is gained with DMD and PMD buses
(2 × 64-bits, core CLK) and the IOD bus (32-bit, PCLK).
ROM-Based Security
The processor has a ROM security feature that provides hardware support for securing user software code by preventing
unauthorized reading from the internal code. When using this
feature, the processor does not boot-load any external code, executing exclusively from internal ROM. Additionally, the
processor is not freely accessible via the JTAG port. Instead, a
unique 64-bit key, which must be scanned in through the JTAG

FAMILY PERIPHERAL ARCHITECTURE
The ADSP-2136x family contains a rich set of peripherals that
support a wide variety of applications, including high quality
audio, medical imaging, communications, military, test equipment, 3D graphics, speech recognition, monitor control,
imaging, and other applications.
Parallel Port
The parallel port provides interfaces to SRAM and peripheral
devices. The multiplexed address and data pins (AD15–0) can
access 8-bit devices with up to 24 bits of address, or 16-bit
devices with up to 16 bits of address. In either mode, 8-bit or
16-bit, the maximum data transfer rate is 55 Mbps.
DMA transfers are used to move data to and from internal
memory. Access to the core is also facilitated through the parallel port register read/write functions. The RD, WR, and ALE
(address latch enable) pins are the control pins for the
parallel port.
Rev. G
|
Serial Peripheral (Compatible) Interface
The processors contain two serial peripheral interface ports
(SPIs). The SPI is an industry-standard synchronous serial link,
enabling the processor’s SPI-compatible port to communicate
with other SPI-compatible devices. The SPI consists of two data
pins, one device select pin, and one clock pin. It is a full-duplex
synchronous serial interface, supporting both master and slave
modes and can operate at a maximum baud rate of fPCLK/4.
The SPI port can operate in a multimaster environment by
interfacing with up to four other SPI-compatible devices, either
acting as a master or slave device. The ADSP-2136x SPIcompatible peripheral implementation also features programmable baud rate, clock phase, and polarities. The SPIcompatible port uses open drain drivers to support a multimaster configuration and to avoid data contention.
Pulse-Width Modulation
The entire PWM module has four groups of four PWM outputs
each. Therefore, this module generates 16 PWM outputs in
total. Each PWM group produces two pairs of PWM signals on
the four PWM outputs.
The PWM module is a flexible, programmable, PWM waveform
generator that can be programmed to generate the required
switching patterns for various applications related to motor and
engine control or audio power control. The PWM generator can
Page 6 of 56 | March 2011
ADSP-21362/ADSP-21363/ADSP-21364/ADSP-21365/ADSP-21366
Serial ports operate in four modes:
generate either center-aligned or edge-aligned PWM waveforms. In addition, it can generate complementary signals on
two outputs in paired mode or independent signals in nonpaired mode (applicable to a single group of four PWM
waveforms).
• Standard DSP serial mode
• Multichannel (TDM) mode
• I2S mode
The PWM generator is capable of operating in two distinct
modes while generating center-aligned PWM waveforms: single
update mode or double update mode. In single update mode,
the duty cycle values are programmable only once per PWM
period. This results in PWM patterns that are symmetrical
about the midpoint of the PWM period. In double update
mode, a second updating of the PWM registers is implemented
at the midpoint of the PWM period. In this mode, it is possible
to produce asymmetrical PWM patterns that produce lower
harmonic distortion in 3-phase PWM inverters.
Digital Audio Interface (DAI)
The digital audio interface (DAI) provides the ability to connect
various peripherals to any of the DSP’s DAI pins (DAI_P20–1).
Programs make these connections using the signal routing unit
(SRU, shown in Figure 1).
The SRU is a matrix routing unit (or group of multiplexers) that
enables the peripherals provided by the DAI to be interconnected under software control. This allows easy use of the
DAI-associated peripherals for a wider variety of applications by
using a larger set of algorithms than is possible with nonconfigurable signal paths.
The DAI includes six serial ports, an S/PDIF receiver/transmitter, a DTCP cipher, a precision clock generator (PCG), eight
channels of asynchronous sample rate converters, an input data
port (IDP), an SPI port, six flag outputs and six flag inputs, and
three timers. The IDP provides an additional input path to the
ADSP-2136x core, configurable as either eight channels of I2S
serial data or as seven channels plus a single 20-bit wide synchronous parallel data acquisition port. Each data channel has
its own DMA channel that is independent from the processor’s
serial ports.
Serial Ports
The processor features six synchronous serial ports that provide
an inexpensive interface to a wide variety of digital and mixedsignal peripheral devices such as Analog Devices’ AD183x family of audio codecs, ADCs, and DACs. The serial ports are made
up of two data lines, a clock, and a frame sync. The data lines
can be programmed to either transmit or receive and each data
line has a dedicated DMA channel.
Serial ports are enabled via 12 programmable and simultaneous
receive or transmit pins that support up to 24 transmit or 24
receive channels of audio data when all six SPORTs are enabled,
or six full duplex TDM streams of 128 channels per frame.
Serial port data can be automatically transferred to and from
on-chip memory via dedicated DMA channels. Each of the
serial ports can work in conjunction with another serial port to
provide TDM support. One SPORT provides two transmit signals while the other SPORT provides the two receive signals.
The frame sync and clock are shared.

• Left-justified sample pair mode
S/PDIF-Compatible Digital Audio Receiver/Transmitter
The S/PDIF transmitter has no separate DMA channels. It
receives audio data in serial format and converts it into a
biphase encoded signal. The serial data input to the transmitter
can be formatted as left-justified, I2S, or right-justified with
word widths of 16, 18, 20, or 24 bits.
The serial data, clock, and frame sync inputs to the S/PDIF
transmitter are routed through the signal routing unit (SRU).
They can come from a variety of sources such as the SPORTs,
external pins, the precision clock generators (PCGs), or the
sample rate converters (SRC) and are controlled by the SRU
control registers.
Digital Transmission Content Protection (DTCP)
The DTCP specification defines a cryptographic protocol for
protecting audio entertainment content from illegal copying,
intercepting, and tampering as it traverses high performance
digital buses, such as the IEEE 1394 standard. Only legitimate
entertainment content delivered to a source device via another
approved copy protection system (such as the DVD content
scrambling system) is protected by this copy protection system.
This feature is available on the ADSP-21362 and
ADSP-21365 processors only. Licensing through DTLA is
required for these products. Visit www.dtcp.com for more
information.
Memory-to-Memory (MTM)
If the DTCP module is not used, the memory-to-memory DMA
module allows internal memory copies for a standard DMA.
Synchronous/Asynchronous Sample Rate Converter (SRC)
The sample rate converter (SRC) contains four SRC blocks and
is the same core as that used in the AD1896 192 kHz stereo
asynchronous sample rate converter and provides up to 140 dB
SNR. The SRC block is used to perform synchronous or
asynchronous sample rate conversion across independent stereo
channels, without using internal processor resources. The four
SRC blocks can also be configured to operate together to convert multichannel audio data without phase mismatches.
Finally, the SRC is used to clean up audio data from jittery clock
sources such as the S/PDIF receiver.
The S/PDIF and SRC are not available on the ADSP-21363
models.
Input Data Port (IDP)
The IDP provides up to eight serial input channels—each with
its own clock, frame sync, and data inputs. The eight channels
are automatically multiplexed into a single 32-bit by eight-deep
FIFO. Data is always formatted as a 64-bit frame and divided
into two 32-bit words. The serial protocol is designed to receive

audio channels in I2S, left-justified sample pair, or right-justified mode. One frame sync cycle indicates one 64-bit left/right
pair, but data is sent to the FIFO as 32-bit words (that is, onehalf of a frame at a time). The processor supports 24- and 32-bit
I2S, 24- and 32-bit left-justified, and 24-, 20-, 18- and 16-bit
right-justified formats.
Precision Clock Generator (PCG)
The precision clock generators (PCG) consist of two units, each
of which generates a pair of signals (clock and frame sync)
derived from a clock input signal. The units, A and B, are identical in functionality and operate independently of each other.
The two signals generated by each unit are normally used as a
serial bit clock/frame sync pair.
Peripheral Timers
The following three general-purpose timers can generate periodic interrupts and be independently set to operate in one of
three modes:
• Pulse waveform generation mode
SYSTEM DESIGN
The following sections provide an introduction to system design
options and power supply issues.
Program Booting
The internal memory of the processor boots at system power-up
from an 8-bit EPROM via the parallel port, an SPI master, an
SPI slave, or an internal boot. Booting is determined by the boot
configuration (BOOT_CFG1–0) pins in Table 5. Selection of the
boot source is controlled via the SPI as either a master or slave
device, or it can immediately begin executing from ROM.
Table 5. Boot Mode Selection

• Pulse width count/capture mode
• External event watchdog mode
Phase-Locked Loop
Each general-purpose timer has one bidirectional pin and four
registers that implement its mode of operation: a 6-bit configuration register, a 32-bit count register, a 32-bit period register,
and a 32-bit pulse width register. A single control and status
register enables or disables all three general-purpose timers
independently.
I/O PROCESSOR FEATURES
The processor’s I/O provides many channels of DMA and controls the extensive set of peripherals described in the previous
sections.
DMA Controller
The processor’s on-chip DMA controllers allow data transfers
without processor intervention. The DMA controller operates
independently and invisibly to the processor core, allowing
DMA operations to occur while the core is simultaneously executing its program instructions. DMA transfers can occur
between the processor’s internal memory and its serial ports, the
SPI-compatible (serial peripheral interface) ports, the IDP
(input data port), the parallel data acquisition port (PDAP), or
the parallel port (PP). See Table 4.

The processors use an on-chip phase-locked loop (PLL) to generate the internal clock for the core. On power-up, the
CLK_CFG1–0 pins are used to select ratios of 32:1, 16:1, and
6:1. After booting, numerous other ratios can be selected via
software control.
The ratios are made up of software configurable numerator values from 1 to 64 and software configurable divisor values of 1, 2,
4, and 8.
Power Supplies
The processor has a separate power supply connection for the
internal (VDDINT), external (VDDEXT), and analog (AVDD/AVSS)
power supplies. The internal and analog supplies must meet the
1.2 V requirement for K, B, and Y grade models, and the 1.0 V
requirement for Y models. (For information on the temperature
ranges offered for this product, see Operating Conditions on
Page 14, Package Information on Page 15, and Ordering Guide
on Page 54.) The external supply must meet the 3.3 V requirement. All external supply pins must be connected to the same
power supply.
Note that the analog supply pin (AVDD) powers the processor’s
internal clock generator PLL. To produce a stable clock, it is recommended that PCB designs use an external filter circuit for the
AVDD pin. Place the filter components as close as possible to the
AVDD/AVSS pins. For an example circuit, see Figure 3. (A
recommended ferrite chip is the muRata BLM18AG102SN1D.)
To reduce noise coupling, the PCB should use a parallel pair of
power and ground planes for VDDINT and GND. Use wide traces
to connect the bypass capacitors to the analog power (AVDD)
and ground (AVSS) pins. Note that the AVDD and AVSS pins
specified in Figure 3 are inputs to the processor and not the analog ground plane on the board—the AVSS pin should connect
directly to digital ground (GND) at the chip.

Target Board JTAG Emulator Connector
Analog Devices’ DSP Tools product line of JTAG emulators
uses the IEEE 1149.1 JTAG test access port of the processor to
monitor and control the target board processor during emulation. Analog Devices’ DSP Tools product line of JTAG
emulators provides emulation at full processor speed, allowing
inspection and modification of memory, registers, and processor stacks. The processor’s JTAG interface ensures that the
emulator does not affect target system loading or timing.
For complete information on Analog Devices’ SHARC DSP
Tools product line of JTAG emulator operation, refer to the
appropriate emulator user’s guide.
DEVELOPMENT TOOLS
The processor is supported with a complete set of
CROSSCORE®† software and hardware development tools,
including Analog Devices emulators and VisualDSP++®‡ development environment. The same emulator hardware that
supports other SHARC processors also fully emulates the
ADSP-2136x processors.
The VisualDSP++ project management environment lets programmers develop and debug an application. This environment
includes an easy-to-use assembler (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 DSP assembly. The SHARC 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
†
‡
• 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
• Perform source level debugging
• Create custom debugger windows
The VisualDSP++ integrated development and debugging environment (IDDE) lets programmers define and manage DSP
software development. Its dialog boxes and property pages let
programmers configure and manage all of the SHARC development 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 memory 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, preemptive, cooperative, and time-sliced scheduling approaches. In
addition, the VDK is 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 generation 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 utilization in a color-coded graphical form, easily move code and data
to different areas of the processor or external memory with a
drag of the mouse and examine runtime stack and heap usage.

The expert linker is fully compatible with the existing linker definition file (LDF), allowing the developer to move between the
graphical and textual environments.
In addition to the software and hardware development tools
available from Analog Devices, third parties provide a wide
range of tools supporting the SHARC processor family. Hardware tools include SHARC processor PC plug-in cards. Third
party software tools include DSP libraries, real-time operating
systems, and block diagram design tools.
Designing an Emulator-Compatible DSP Board (Target)
The Analog Devices family of emulators are tools that every
DSP 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. Nonintrusive incircuit emulation is assured by the use of the processor’s JTAG
interface. (The emulator does not affect target system loading or
timing.) 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 DSP 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 DSP’s JTAG port to the emulator.
For details on target board design issues including mechanical
layout, single processor connections, multiprocessor scan
chains, signal buffering, signal termination, and emulator pod
logic, refer to the Analog Devices JTAG Emulation Technical
Reference (EE-68) on the Analog Devices website, www.analog.com. (Perform a site search on “EE-68.”) This document is
updated regularly to keep pace with improvements to emulator
support.
With a full version of VisualDSP++ installed (sold separately),
engineers can develop software for the EZ-KIT Lite or any custom defined system. Connecting one of Analog Devices’ JTAG
emulators to the EZ-KIT Lite board enables high speed, nonintrusive emulation.

RELATED SIGNAL CHAINS
A signal chain is a series of signal-conditioning electronic components that receive input (data acquired from sampling either
real-time phenomena or from stored data) in tandem, with the
output of one portion of the chain supplying input to the next.
Signal chains are often used in signal processing applications to
gather and process data or to apply system controls based on
analysis of real-time phenomena. For more information about
this term and related topics, see the “signal chain” entry in the
Glossary of EE Terms on the Analog Devices website.
Analog Devices eases signal processing system development by
providing signal processing components that are designed to
work together well. A tool for viewing relationships between
specific applications and related components is available on the
www.analog.com website.

Evaluation Kit
Analog Devices offers a range of EZ-KIT Lite®† evaluation platforms 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
platform 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, a power supply, and
a USB cable. All evaluation versions of the software tools are
limited for use only with the EZ-KIT Lite product.
• Graphical circuit block diagram presentation of signal
chains for a variety of circuit types and applications
• Drill down links for components in each chain to selection
guides and application information
• Reference designs applying best practice design techniques
The USB controller on the EZ-KIT Lite board connects the
board to the USB port of the user’s PC, enabling the
VisualDSP++ evaluation suite to emulate the on-board processor in-circuit. This permits the customer to download, execute,
and debug programs for the EZ-KIT Lite system. It also allows
in-circuit programming of the on-board flash device to store
user-specific boot code, enabling the board to run as a standalone unit without being connected to the PC.

Function
Parallel Port Address/Data. The ADSP-2136x parallel port and its corresponding DMA
unit output addresses and data for peripherals on these multiplexed pins. The multiplex
state is determined by the ALE pin. The parallel port can operate in either 8-bit or 16-bit
mode. Each AD pin has a 22.5 kΩ internal pull-up resistor. For details about the AD pin
operation, refer to the ADSP-2136x SHARC Processor Hardware Reference .
For 8-bit mode: ALE is automatically asserted whenever a change occurs in the upper 16
external address bits, ADDR23–8; ALE is used in conjunction with an external latch to
retain the values of the ADDR23–8.
For detailed information on I/O operations and pin multiplexing, refer to the ADSP-2136x
SHARC Processor Hardware Reference.
Parallel Port Read Enable. RD is asserted low whenever the processor reads 8-bit or 16bit data from an external memory device. When AD15–0 are flags, this pin remains
deasserted. RD has a 22.5 kΩ internal pull-up resistor.
Parallel Port Write Enable. WR is asserted low whenever the processor writes 8-bit or
16-bit data to an external memory device. When AD15–0 are flags, this pin remains
deasserted. WR has a 22.5 kΩ internal pull-up resistor.
Parallel Port Address Latch Enable. ALE is asserted whenever the processor drives a
new address on the parallel port address pins. On reset, ALE is active high. However, it
can be reconfigured using software to be active low. When AD15–0 are flags, this pin
remains deasserted. ALE has a 20 kΩ internal pull-down resistor.

Digital Audio Interface Pins. These pins provide the physical interface to the SRU. The
SRU configuration registers define the combination of on-chip peripheral inputs or
outputs connected to the pin and to the pin’s output enable. The configuration registers
of these peripherals then determine the exact behavior of the pin. Any input or output
signal present in the SRU can be routed to any of these pins. The SRU provides the
connection from the serial ports, input data port, precision clock generators and timers,
sample rate converters and SPI to the DAI_P20–1 pins. These pins have internal 22.5 kΩ
pull-up resistors that are enabled on reset. These pull-ups can be disabled using the
DAI_PIN_PULLUP register.

Three-state with

driven high in SPImaster boot mode
Function
Serial Peripheral Interface Clock Signal. Driven by the master, this signal controls the
rate at which data is transferred. The master can transmit data at a variety of baud rates.
SPICLK cycles once for each bit transmitted. SPICLK is a gated clock active during data
transfers, only for the length of the transferred word. Slave devices ignore the serial clock
if the slave select input is driven inactive (high). SPICLK is used to shift out and shift in
the data driven on the MISO and MOSI lines. The data is always shifted out on one clock
edge and sampled on the opposite edge of the clock. Clock polarity and clock phase
relative to data are programmable into the SPICTL control register and define the transfer
format. SPICLK has a 22.5 kΩ internal pull-up resistor.
I
Input only
Serial Peripheral Interface Slave Device Select. An active low signal used to select the
SPIDS
processor as an SPI slave device. This input signal behaves like a chip select, and is
provided by the master device for the slave devices. In multimaster mode the processor’s
SPIDS signal can be driven by a slave device to signal to the processor (as SPI master)
that an error has occurred, as some other device is also trying to be the master device. If
asserted low when the device is in master mode, it is considered a multimaster error. For
a single-master, multiple-slave configuration where flag pins are used, this pin must be
tied or pulled high to VDDEXT on the master device. For processor to processor SPI interaction, any of the master processor’s flag pins can be used to drive the SPIDS signal on
the SPI slave device.
MOSI
I/O (O/D)
Three-state with
SPI Master Out Slave In. If the ADSP-2136x is configured as a master, the MOSI pin
(pu)
pull-up enabled,
becomes a data transmit (output) pin, transmitting output data. If the processor is
driven low in SPIconfigured as a slave, the MOSI pin becomes a data receive (input) pin, receiving input
master boot mode data. In an SPI interconnection, the data is shifted out from the MOSI output pin of the
master and shifted into the MOSI input(s) of the slave(s). MOSI has a 22.5 kΩ internal pullup resistor.
MISO
I/O (O/D)
Three-state with
SPI Master In Slave Out. If the ADSP-2136x is configured as a master, the MISO pin
(pu)
pull-up enabled
becomes a data receive (input) pin, receiving input data. If the processor is configured
as a slave, the MISO pin becomes a data transmit (output) pin, transmitting output data.
In an SPI interconnection, the data is shifted out from the MISO output pin of the slave
and shifted into the MISO input pin of the master. MISO has a 22.5 kΩ internal pull-up
resistor. MISO can be configured as O/D by setting the OPD bit in the SPICTL register.
Note: Only one slave is allowed to transmit data at any given time. To enable broadcast
transmission to multiple SPI slaves, the processor’s MISO pin can be disabled by setting
Bit 5 (DMISO) of the SPICTL register equal to 1.
CLKIN
I
Input only
Local Clock In. Used in conjunction with XTAL. CLKIN is the ADSP-2136x clock input. It
configures the ADSP-2136x to use either its internal clock generator or an external clock
source. Connecting the necessary components to CLKIN and XTAL enables the internal
clock generator. Connecting the external clock to CLKIN while leaving XTAL unconnected configures the processors to use the external clock source such as an external
clock oscillator. The core is clocked either by the PLL output or this clock input depending
on the CLK_CFG1–0 pin settings. CLKIN should not be halted, changed, or operated
below the specified frequency.

I

Core to CLKIN Ratio Control. These pins set the start up clock frequency. Note that the
operating frequency can be changed by programming the PLL multiplier and divider in
the PMCTL register at any time after the core comes out of reset. The allowed values are:
00 = 6:1
01 = 32:1
10 = 16:1
11 = reserved.

Switching Characteristics specify how the processor changes its
signals. Circuitry external to the processor must be designed for
compatibility with these signal characteristics. Switching characteristics describe what the processor will do in a given
circumstance. Use switching characteristics to ensure that any
timing requirement of a device connected to the processor (such
as memory) is satisfied.
Timing Requirements apply to signals that are controlled by circuitry external to the processor, such as the data input for a read
operation. Timing requirements guarantee that the processor
operates correctly with other devices.
ESD CAUTION
ESD (electrostatic discharge) sensitive device.
Charged devices and circuit boards can discharge
without detection. Although this product features
patented or proprietary protection circuitry, damage
may occur on devices subjected to high energy ESD.
Therefore, proper ESD precautions should be taken to
avoid performance degradation or loss of functionality.
MAXIMUM POWER DISSIPATION
See Estimating Power for the ADSP-21362 SHARC Processors
(EE-277) for detailed thermal and power information regarding
maximum power dissipation. For information on package thermal specifications, see Thermal Characteristics on Page 45.
Core Clock Requirements
The processor’s internal clock (a multiple of CLKIN) provides
the clock signal for timing internal memory, processor core, and
serial ports. During reset, program the ratio between the processor’s internal clock frequency and external (CLKIN) clock
frequency with the CLK_CFG1–0 pins.
The processor’s internal clock switches at higher frequencies
than the system input clock (CLKIN). To generate the internal
clock, the processor uses an internal phase-locked loop (PLL,
see Figure 5). This PLL-based clocking minimizes the skew
between the system clock (CLKIN) signal and the processor’s
internal clock.
Voltage Controlled Oscillator
ABSOLUTE MAXIMUM RATINGS
Stresses greater than those listed in Table 8 may cause permanent damage to the device. These are stress ratings only;
functional operation of the device at these or any other conditions greater than those indicated in the operational sections of
this specification is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device
reliability.

In application designs, the PLL multiplier value should be
selected in such a way that the VCO frequency never exceeds
fVCO specified in Table 11.

• The product of CLKIN and PLLM must never exceed fVCO
(max) in Table 11 if the input divider is enabled
(INDIV = 1).
Note the definitions of the clock periods that are a function of
CLKIN and the appropriate ratio control shown in Table 9. All
of the timing specifications for the ADSP-2136x peripherals are
defined in relation to tPCLK. Refer to the peripheral specific section for each peripheral’s timing information.
The VCO frequency is calculated as follows:
fVCO = 2 × PLLM × fINPUT
fCCLK = (2 × PLLM × fINPUT) ÷ (2 × PLLN)

During reset, the PLLM value is derived from the ratio selected
using the CLK_CFG pins in hardware.

PMCTL register. During reset this value is 1.

Power-Up Sequencing
three-state leakage current pull-up, pull-down, may be observed
on any pin, even if that is an input only (for example the RESET
pin) until the VDDINT rail has powered up.
The timing requirements for processor startup are given in
Table 10. Note that during power-up, when the VDDINT power
supply comes up after VDDEXT, a leakage current of the order of

Valid VDDINT/VDDEXT assumes that the supplies are fully ramped to their 1.2 V rails and 3.3 V rails. Voltage ramp rates can vary from microseconds to hundreds of milliseconds,
depending on the design of the power supply subsystem.
2
Assumes a stable CLKIN signal, after meeting worst-case start-up timing of crystal oscillators. Refer to your crystal oscillator manufacturer’s data sheet for start-up time.
Assume a 25 ms maximum oscillator start-up time if using the XTAL pin and internal oscillator circuit in conjunction with an external crystal.
3
Applies after the power-up sequence is complete. Subsequent resets require a minimum of 4 CLKIN cycles for RESET to be held low to properly initialize and propagate
default states at all I/O pins.
4
The 4096 cycle count depends on tSRST specification in Table 12. If setup time is not met, 1 additional CLKIN cycle can be added to the core reset time, resulting in 4097 cycles
maximum.

This timing is only valid when the SRU is configured such that
the precision clock generator (PCG) takes its inputs directly
from the DAI pins (via pin buffers) and sends its outputs
directly to the DAI pins. For the other cases, where the PCG’s
inputs and outputs are not directly routed to/from DAI pins (via
pin buffers) there is no timing data available. All timing parameters and switching characteristics apply to external DAI pins

Serial Ports
To determine whether communication is possible between two
devices at clock speed n, the following specifications must be
confirmed: 1) frame sync (FS) delay and frame sync setup and
hold, 2) data delay and data setup and hold, and 3) serial clock
(SCLK) width.
Serial port signals are routed to the DAI_P20–1 pins using the
SRU. Therefore, the timing specifications provided below are
valid at the DAI_P20–1 pins.

S/PDIF Transmitter
Serial data input to the S/PDIF transmitter can be formatted as
left justified, I2S, or right justified with word widths of 16-, 18-,
20-, or 24-bits. The following sections provide timing for the
transmitter.
S/PDIF Transmitter-Serial Input Waveforms
Figure 29 shows the right-justified mode. Frame sync is high for
the left channel and low for the right channel. Data is valid on
the rising edge of serial clock. The MSB is delayed the minimum
in 24-bit output mode or the maximum in 16-bit output mode
from a frame sync transition, so that when there are 64 serial
clock periods per frame sync period, the LSB of the data is rightjustified to the next frame sync transition.

OUTPUT DRIVE CURRENTS
CAPACITIVE LOADING
Figure 37 shows typical I-V characteristics for the output drivers of the processor. The curves represent the current drive
capability of the output drivers as a function of output voltage.
Output delays and holds are based on standard capacitive loads:
30 pF on all pins (see Figure 38). Figure 42 shows graphically
how output delays and holds vary with load capacitance. The
graphs of Figure 40, Figure 41, and Figure 42 may not be linear
outside the ranges shown for Typical Output Delay versus Load
Capacitance and Typical Output Rise Time (20% to 80%,
V = Min) versus Load Capacitance.

The processor is rated for performance over the temperature
range specified in Operating Conditions on Page 14.
Table 42 through Table 44 airflow measurements comply with
JEDEC standards JESD51-2 and JESD51-6 and the junction-toboard measurement complies with JESD51-8. Test board and
thermal via design comply with JEDEC standards JESD51-9
(BGA) and JESD51-5 (LQFP_EP). The junction-to-case measurement complies with MIL-STD-883. All measurements use a
2S2P JEDEC test board.
Industrial applications using the BGA package require thermal
vias, to an embedded ground plane, in the PCB. Refer to JEDEC
standard JESD51-9 for printed circuit board thermal ball land
and thermal via design information.
Industrial applications using the LQFP_EP package require
thermal trace squares and thermal vias, to an embedded ground
plane, in the PCB. Refer to JEDEC standard JESD51-5 for more
information.
To determine the junction temperature of the device while on
the application PCB, use:
