GENERAL DESCRIPTION
The ADSP-21364 SHARC processor is a member of the SIMD
SHARC family of DSPs that feature Analog Devices' Super Harvard Architecture. The ADSP-21364 is source code compatible
with the ADSP-2126x, and ADSP-2116x DSPs as well as with

The block diagram of the ADSP-21364 on Page 6, illustrates the
following architectural features:
As shown in the functional block diagram on Page 1, the
ADSP-21364 uses two computational units to deliver a significant performance increase over previous SHARC processors on
a range of signal processing algorithms. Fabricated in a state-ofthe-art, high speed, CMOS process, the ADSP-21364 processor
achieves an instruction cycle time of 3.0 ns at 333 MHz. With its
SIMD computational hardware, the ADSP-21364 can perform 2
GFLOPS running at 333 MHz.
• Digital Audio Interface that includes two precision clock
generators (PCG), an input data port (IDP), an S/PDIF

Figure 2 on Page 4 shows one sample configuration of a SPORT
using the precision clock generators to interface with an I2S
ADC and an I2S DAC with a much lower jitter clock than the
serial port would generate itself. Many other SRU configurations are possible.
ADSP-21364 FAMILY CORE ARCHITECTURE
The ADSP-21364 is code compatible at the assembly level with
the ADSP-2126x, ADSP-21160 and ADSP-21161, and with the
first generation ADSP-2106x SHARC DSPs. The ADSP-21364
shares architectural features with the ADSP-2126x and
ADSP-2116x SIMD SHARC processors, as detailed in the following sections.
SIMD Computational Engine
The ADSP-21364 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 may 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.
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.
• On-Chip SRAM (3M bit)
• On-Chip mask-programmable ROM (4M bit)

Figure 2. ADSP-21364 System Sample Configuration
Independent, Parallel Computation Units
Single-Cycle Fetch of Instruction and Four Operands
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 singleprecision floating-point, 40-bit extended precision floatingpoint, and 32-bit fixed-point data formats.
The ADSP-21364 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 1 on Page 1). With the ADSP-21364’s 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.
Data Register File
A general-purpose data register file is contained in each
processing element. 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)
register 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.

Instruction Cache
The ADSP-21364 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 ADSP-21364’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
September 2004
Preliminary Technical Data
ADSP-21364
signal processing, and are commonly used in digital filters and
Fourier transforms. The two DAGs of the ADSP-21364 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.
On-Chip Memory
The ADSP-21364 contains three megabits of internal SRAM.
Each block can be configured for different combinations of code
and data storage (see Table 2 on Page 5). Each memory block
supports single-cycle, independent accesses by the core processor and I/O processor. The ADSP-21364 memory architecture,
in combination with its separate on-chip buses, allow two data
transfers from the core and one from the I/O processor, in a single cycle.
Flexible Instruction Set
The 48-bit instruction word accommodates a variety of parallel
operations, for concise programming. For example, the
ADSP-21364 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.
The ADSP-21364’s, 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 three megabits. 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 may 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.

ADSP-21364
Preliminary Technical Data
Using the DM bus and PM buses, with one dedicated to each
memory block assures single-cycle execution with two data
transfers. In this case, the instruction must be available in the
cache.
Digital Audio Interface (DAI)
DMA Controller
Programs make these connections using the Signal Routing
Unit (SRU, shown in Figure 3).
The Digital Audio Interface (DAI) provides the ability to connect various peripherals to any of the SHARCs DAI pins
(DAI_P20–1).
The ADSP-21364’s on-chip DMA controller allows 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 ADSP-21364’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. Twenty-five channels of DMA are
available on the ADSP-21364—two for the SPI interface, two for
memory-to-memory transfers, twelve via the serial ports, eight
via the Input Data Port, and one via the processor’s parallel
port. Programs can be downloaded to the ADSP-21364 using
DMA transfers. Other DMA features include interrupt generation upon completion of DMA transfers, and DMA chaining for
automatic linked DMA transfers.
The DAI also includes six serial ports, two precision clock generators (PCGs), 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-21364 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 ADSP-21364's serial ports.

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 much wider variety of applications
by using a larger set of algorithms than is possible with nonconfigurable signal paths.
GPI O FLAGS/I RQ/TIMEXP
The ADSP-21364 features six synchronous serial ports that provide an inexpensive interface to a wide variety of digital and
mixed-signal 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 frame sync. The
data lines can be programmed to either transmit or receive and
each data line has a dedicated DMA channel.

The serial ports operate at a maximum data rate of 50M bits/s.
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.
Serial ports operate in four modes:
• Standard DSP serial mode
• Multichannel (TDM) mode
SPDIF (RX/ TX )
• I2S mode
SRC (8 CHANNELS)
• Left-justified sample pair mode

Left-justified sample pair mode is a mode where in each frame
sync cycle two samples of data are transmitted/received—one
sample on the high segment of the frame sync, the other on the
low segment of the frame sync. Programs have control over various attributes of this mode.
September 2004
Preliminary Technical Data
ADSP-21364
Each of the serial ports supports the left-justified sample pair
and I2S protocols (I2S is an industry standard interface commonly used by audio codecs, ADCs and DACs such as the
Analog Devices AD183x family), with two data pins, allowing
four left-justified sample pair or I2S channels (using two stereo
devices) per serial port, with a maximum of up to 24 I2S channels. The serial ports permit little-endian or big-endian
transmission formats and word lengths selectable from 3 bits to
32 bits. For the left-justified sample pair and I2S modes, dataword lengths are selectable between 8 bits and 32 bits. Serial
ports offer selectable synchronization and transmit modes as
well as optional µ-law or A-law companding selection on a per
channel basis. Serial port clocks and frame syncs can be internally or externally generated.
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- or 16bit, the maximum data transfer rate is 55M bytes/sec.
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.
Serial Peripheral (Compatible) Interface
The ADSP-21364 SHARC processor contains two Serial Peripheral Interface ports (SPIs). The SPI is an industry standard
synchronous serial link, enabling the ADSP-21364 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. 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-21364 SPI compatible peripheral implementation also features programmable baud rate and clock phase
and polarities. The ADSP-21364 SPI compatible port uses open
drain drivers to support a multimaster configuration and to
avoid data contention.
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 providing up to 140dB
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.

S/PDIF Compatible Digital Audio Receiver/Transmitter
and Synchronous/Asynchronous Sample Rate Converter
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.
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 providing up to 140dB
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.
Pulse Width Modulation
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
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).
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 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
around the mid-point of the PWM period. In double update
mode, a second updating of the PWM registers is implemented
at the mid-point of the PWM period. In this mode, it is possible
to produce asymmetrical PWM patterns that produce lower
harmonic distortion in three-phase PWM inverters.

ADSP-21364
Preliminary Technical Data
Timers
The ADSP-21364 has a total of four timers: a core timer able to
generate periodic software interrupts and three general purpose
timers that can generate periodic interrupts and be independently set to operate in one of three modes:
10⍀
VDDINT
AVDD
0.1␮F
0.01␮F
AVSS
• Pulse Waveform Generation mode
• Pulse Width Count /Capture mode
Figure 4. Analog Power (AVDD) Filter Circuit
• External Event Watchdog mode
The core timer can be configured to use FLAG3 as a Timer
Expired signal, and 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.
Program Booting
The internal memory of the ADSP-21364 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 (BOOTCFG1–0) pins (see Table 6 on
Page 14). Selection of the boot source is controlled via the SPI as
either a master or slave device.
Phase-Locked Loop
The ADSP-21364 uses an on-chip Phase-Locked Loop (PLL) to
generate the internal clock for the core. On power up, the
CLKCFG1–0 pins are used to select ratios of 32:1, 16:1, and 6:1
(see Table 7 on Page 14). After booting, numerous other ratios
can be selected via software control. The ratios are made up of
software configurable numerator values from 1 to 32 and software configurable divisor values of 1, 2, 4, 8, and 16.
Power Supplies
The ADSP-21364 has separate power supply connections for the
internal (VDDINT), external (VDDEXT), and analog (AVDD/AVSS)
power supplies. The internal and analog supplies must meet the
1.2 V requirement. 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 (AVDD) powers the ADSP-21364’s
clock generator PLL. To produce a stable clock, programs
should provide an external circuit to filter the power input to
the AVDD pin. Place the filter as close as possible to the pin. For
an example circuit, see Figure 4. To prevent noise coupling, use
a wide trace for the analog ground (AVSS) signal and install a
decoupling capacitor as close as possible to the pin. Note that
the AVSS and AVDD pins specified in Figure 4 are inputs to the
processor and not the analog ground plane on the board.
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 ADSP-21364 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
Rev. PrB
|
Page 8 of 52 |
inspection and modification of memory, registers, and processor stacks. The processor's JTAG interface ensures that the
emulator will not affect target system loading or timing.
For complete information on Analog Devices’ SHARC DSP
Tools product line of JTAG emulator operation, see the appropriate “Emulator Hardware User's Guide”.
DEVELOPMENT TOOLS
The ADSP-21364 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-21364.
The VisualDSP++ project management environment lets programmers develop and debug an application. This environment
includes an easy to use assembler (which is based on an algebraic syntax), an archiver (librarian/library builder), a linker, a
loader, a cycle-accurate instruction-level simulator, a C/C++
compiler, and a C/C++ runtime library that includes DSP and
mathematical functions. A key point for these tools is C/C++
code efficiency. The compiler has been developed for efficient
translation of C/C++ code to 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 non intrusively poll
the processor as it is running the program. This feature, unique
to VisualDSP++, enables the software developer to passively
gather important code execution metrics without interrupting
the real-time characteristics of the program. Essentially, the
developer can identify bottlenecks in software quickly and efficiently. By using the profiler, the programmer can focus on
those areas in the program that impact performance and take
corrective action.
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)
• Insert breakpoints
September 2004
Preliminary Technical Data
ADSP-21364
• Set conditional breakpoints on registers, memory,
and stacks
• Fill, dump, and graphically plot the contents of memory
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.
• Perform source level debugging
Designing an Emulator-Compatible DSP Board (Target)
• Create custom debugger windows
The Analog Devices family of emulators are tools that every
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 DSP. 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. The emulator uses the TAP to access the internal features of the processor, allowing the developer to load code, set
breakpoints, observe variables, observe memory, and examine
registers. The processor must be halted to send data and commands, but once an operation has been completed by the
emulator, the processor system is set running at full speed with
no impact on system timing.
• Trace instruction execution
• Perform linear or statistical profiling of program execution
The VisualDSP++ 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 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 generation of various VDK based objects, and visualizing the
system state, when debugging an application that uses the VDK.
VisualDSP++ Component Software Engineering (VCSE) is
Analog Devices’ technology for creating, using, and reusing
software components (independent modules of substantial
functionality) to quickly and reliably assemble software applications. Download components from the Web and drop them into
the application. Publish component archives from within VisualDSP++. VCSE supports component implementation in
C/C++ or assembly language.
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 the
drag of the mouse, examine run time 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.

To use these emulators, the target board must include a header
that connects the processor’s JTAG port to the emulator.

layout, single processor connections, multiprocessor scan
chains, signal buffering, signal termination, and emulator pod
logic, see the EE-68: Analog Devices JTAG Emulation Technical
Reference on the Analog Devices website (www.analog.com)—

to keep pace with improvements to emulator support.
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
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 VisualDSP++ 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 custom defined system. Connecting one of Analog Devices JTAG
emulators to the EZ-KIT Lite board enables high-speed, nonintrusive emulation.

PIN FUNCTION DESCRIPTIONS
ADSP-21364 pin definitions are listed below. Inputs identified
as synchronous (S) must meet timing requirements with respect
to CLKIN (or with respect to TCK for TMS and TDI). Inputs
identified as asynchronous (A) can be asserted asynchronously
to CLKIN (or to TCK for TRST). Tie or pull unused inputs to
VDDEXT or GND, except for the following:
• DAI_Px, SPICLK, MISO, MOSI, EMU, TMS, TRST, TDI,
and AD15–0 (NOTE: These pins have pullup resistors.)
The following symbols appear in the Type column of Table 3:
A = Asynchronous, G = Ground, I = Input, O = Output,
P = Power Supply, S = Synchronous, (A/D) = Active Drive,
(O/D) = Open Drain, and T = Three-State, (pd) = pulldown
resistor, (pu) = pullup resistor. .

Function
Parallel Port Address/Data. The ADSP-21364 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 pullup resistor. See Address
Data Modes on Page 14 for details of the AD pin operation.
For 8-bit mode: ALE is automatically asserted whenever a change occurs in the upper
16 external address bits, A23–8; ALE is used in conjunction with an external latch to
retain the values of the A23–8.
For 16-bit mode: ALE is automatically asserted whenever a change occurs in the
address bits, A15–0; ALE is used in conjunction with an external latch to retain the
values of the A15–0. To use these pins as flags (FLAGS15–0) or PWMs (PWM15–0), 1)
set (=1) bit 20 of the SYSCTL register to disable the parallel port, 2) set (=1) bits 22–25
of the SYSCTL register to enable FLAGS in groups of four (bit 22 for FLAGS3–0, bit 23
for FLAGS7–4 etc.) or, set (=1) bits 26–29 of the SYSCTL register to enable PWMs in
groups of four (bit 26 for PWM0–3, bit 27 for PWM4–7, and so on). When used as an
input, the IDP Channel0 can use these pins for parallel input data.
Parallel Port Read Enable. RD is asserted low whenever the processor reads 8-bit or
16-bit data from an external memory device. When AD15–0 are flags, this pin remains
deasserted. RD has a 22.5 kΩ internal pullup 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 pullup 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 pulldown resistor.
Flag Pins. Each flag pin is configured via control bits as either an input or output. As
an input, it can be tested as a condition. As an output, it can be used to signal external
peripherals. These pins can be used as an SPI interface slave select output during SPI
mastering. These pins are also multiplexed with the IRQx and the TIMEXP signals.
In SPI master boot mode, FLAG0 is the slave select pin that must be connected to an
SPI EPROM. FLAG0 is configured as a slave select during SPI master boot. When bit 16
is set (=1) in the SYSCTL register, FLAG0 is configured as IRQ0.
When bit 17 is set (=1) in the SYSCTL register, FLAG1 is configured as IRQ1.
When bit 18 is set (=1) in the SYSCTL register, FLAG2 is configured as IRQ2.
When bit 19 is set (=1) in the SYSCTL register, FLAG3 is configured as TIMEXP which
indicates that the system timer has expired.

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 determines the exact behavior of the pin. Any input
or output signal present in the SRU may 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 pullup resistors which are enabled on reset. These pullups can
be disabled in the DAI_PIN_PULLUP register.
Serial Peripheral Interface Clock Signal. Driven by the master, this signal controls
the rate at which data is transferred. The master may transmit data at a variety of baud
rates. SPICLK cycles once for each bit transmitted. SPICLK is a gated clock that is 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 pullup resistor.
Serial Peripheral Interface Slave Device Select. An active low signal used to select
the 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 DSPs
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 ADSP-21364 to
ADSP-21364 SPI interaction, any of the master ADSP-21364's flag pins can be used to
drive the SPIDS signal on the ADSP-21364 SPI slave device.
SPI Master Out Slave In. If the ADSP-21364 is configured as a master, the MOSI pin
becomes a data transmit (output) pin, transmitting output data. If the ADSP-21364 is
configured as a slave, the MOSI pin becomes a data receive (input) pin, receiving input
data. In an ADSP-21364 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.
SPI Master In Slave Out. If the ADSP-21364 is configured as a master, the MISO pin
becomes a data receive (input) pin, receiving input data. If the ADSP-21364 is
configured as a slave, the MISO pin becomes a data transmit (output) pin, transmitting
output data. In an ADSP-21364 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 pullup 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 may be disabled by
setting (=1) bit 5 (DMISO) of the SPICTL register.
Boot Configuration Select. This pin is used to select the boot mode for the processor.
The BOOTCFG pins must be valid before reset is asserted. See Table 6 for a description
of the boot modes.

Local Clock In. Used in conjunction with XTAL. CLKIN is the ADSP-21364 clock input.
It configures the ADSP-21364 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 ADSP-21364 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 CLKCFG1–0 pin settings. CLKIN may not be halted, changed, or
operated below the specified frequency.
Crystal Oscillator Terminal. Used in conjunction with CLKIN to drive an external
crystal.
Core/CLKIN Ratio Control. These pins set the start up clock frequency. See Table 7
for a description of the clock configuration modes.
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.
Local Clock Out/ Reset Out. Drives out the core reset signal to an external device.
CLKOUT can also be configured as a reset out pin.The functionality can be switched
between the PLL output clock and reset out by setting bit 12 of the PMCTREG register.
The default is reset out.
Processor Reset. Resets the ADSP-21364 to a known state. Upon deassertion, there
is a 4096 CLKIN cycle latency for the PLL to lock. After this time, the core begins
program execution from the hardware reset vector address. The RESET input must be
asserted (low) at power-up.
Test Clock (JTAG). Provides a clock for JTAG boundary scan. TCK must be asserted
(pulsed low) after power-up or held low for proper operation of the ADSP-21364.
Test Mode Select (JTAG). Used to control the test state machine. TMS has a 22.5 kΩ
internal pullup resistor.
Test Data Input (JTAG). Provides serial data for the boundary scan logic. TDI has a
22.5 kΩ internal pullup resistor.
Test Data Output (JTAG). Serial scan output of the boundary scan path.
Test Reset (JTAG). Resets the test state machine. TRST must be asserted (pulsed low)
after power-up or held low for proper operation of the ADSP-21364. TRST has a
22.5 kΩ internal pullup resistor.
Emulation Status. Must be connected to the ADSP-21364 Analog Devices processor
Tools product line of JTAG emulators target board connector only. EMU has a 22.5 kΩ
internal pullup resistor.
Core Power Supply. Nominally +1.2 V dc and supplies the processor’s core processor
(13 pins on the Mini-BGA package, 32 pins on the LQFP package).
I/O Power Supply. Nominally +3.3 V dc. (6 pins on the Mini-BGA package, 10 pins on
the LQFP package).
Analog Power Supply. Nominally +1.2 V dc and supplies the processor’s internal PLL
(clock generator). This pin has the same specifications as VDDINT, except that added
filtering circuitry is required. For more information, see Power Supplies on Page 8.
Analog Power Supply Return.
Power Supply Return. (54 pins on the Mini-BGA package, 39 pins on the LQFP
package).

Stresses greater than those listed above 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.
ESD SENSITIVITY
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the ADSP-21364 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
TIMING SPECIFICATIONS
The ADSP-21364’s internal clock (a multiple of CLKIN) provides the clock signal for timing internal memory, processor
core, serial ports, and parallel port (as required for read/write
strobes in asynchronous access mode). During reset, program
the ratio between the processor’s internal clock frequency and
external (CLKIN) clock frequency with the CLKCFG1–0 pins.
Rev. PrB
|
Page 16 of 52 |
To determine switching frequencies for the serial ports, divide
down the internal clock, using the programmable divider control of each port (DIVx for the serial ports).
The ADSP-21364’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).
This PLL-based clocking minimizes the skew between the system clock (CLKIN) signal and the processor’s internal clock (the
clock source for the parallel port logic and I/O pads).

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.

Use the exact timing information given. Do not attempt to
derive parameters from the addition or subtraction of others.
While addition or subtraction would yield meaningful results
for an individual device, the values given in this data sheet
reflect statistical variations and worst cases. Consequently, it is
not meaningful to add parameters to derive longer times. See
Figure 38 on page 43 under Test Conditions for voltage reference levels.
Description1
CLKIN Clock Period
(Processor) Core Clock Period
(Peripheral) Clock Period = 2 × tCCLK
Serial Port Clock Period = (tPCLK) × SR
SPI Clock Period = (tPCLK) × SPIR
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.
where:
SR = serial port-to-core clock ratio (wide range, determined by
SPORT CLKDIV)
SPIR = SPI-to-Core Clock Ratio (wide range, determined by
SPIBAUD register)

Figure 5 shows Core to CLKIN ratios of 6:1, 16:1 and 32:1 with
external oscillator or crystal. Note that more ratios are possible
and can be set through software using the power management
control register (PMCTL). For more information, see the

The ADSP-21364 can use an external clock or a crystal. See
CLKIN pin description. The programmer can configure the
ADSP-21364 to use its internal clock generator by connecting
the necessary components to CLKIN and XTAL. Figure 8 shows
the component connections used for a crystal operating in fundamental mode. Note that the clock rate is achieved using a
16.67 MHz crystal and a PLL multiplier ratio 16:1
(CCLK:CLKIN achieves a clock speed of 266 MHz). To achieve
the full core clock rate, programs need to configure the multiplier bits in the PMCTL register.

Serial Ports
To determine whether communication is possible between two
devices at clock speed n, the following specifications must be
confirmed: 1) frame sync delay and frame sync setup and hold,
2) data delay and data setup and hold, and 3) SCLK width.
Serial port signals (SCLK, FS, DxA,/DxB) 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.

SPDIF Transmitter
Serial data input to the SPDIF 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.
SPDIF Transmitter—Serial Input Waveforms
Figure 27 shows the right-justified mode. LRCLK is HI for the
left channel and LO for the right channel. Data is valid on the
rising edge of SCLK. The MSB is delayed 12-bit clock periods
(in 20-bit output mode) or 16-bit clock periods (in 16-bit output
LRCLK
mode) from an LRCLK transition, so that when there are 64
SCLK periods per LRCLK period, the LSB of the data will be
right-justified to the next LRCLK transition.

OUTPUT DRIVE CURRENTS
CAPACITIVE LOADING
Figure 36 shows typical I-V characteristics for the output drivers of the ADSP-21364. 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 37). Figure 41 shows graphically
how output delays and holds vary with load capacitance. The
graphs of Figure 39, Figure 40, and Figure 41 may not be linear
outside the ranges shown for Typical Output Delay vs. Load
Capacitance and Typical Output Rise Time (20%-80%, V=Min)
vs. Load Capacitance.

RISE AND FALL TIMES (ns)
Timing is measured on signals when they cross the 1.5 V level as
described in Figure 38 on Page 43. All delays (in nanoseconds)
are measured between the point that the first signal reaches
1.5 V and the point that the second signal reaches 1.5 V.

THERMAL CHARACTERISTICS
The ADSP-21364 processor is rated for performance to a maximum junction temperature of 125°C.
Table 39 airflow measurements comply with JEDEC standards
JESD51-2 and JESD51-6 and the junction-to-board measurement complies with JESD51-8. Test board and thermal via
design comply with JEDEC standards JESD51-9 (Mini-BGA)
and JESD51-5 (Integrated Heatsink LQFP). The junction-tocase measurement complies with MIL- STD-883. All measurements use a 2S2P JEDEC test board.
Industrial applications using the Mini-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 package require thermal trace squares and
thermal vias, to an embedded ground plane, in the PCB. The
bottom side heat slug must be soldered to the thermal trace
squares. Refer to JEDEC Standard JESD51-5 for more
information.
To determine the Junction Temperature of the device while on
the application PCB, use:
T J = T CASE + ( Ψ JT × P D )
where:
TJ = Junction temperature ×C
TCASE = Case temperature (×C) measured at the top center of
the package
ΨJT = Junction-to-Top (of package) characterization parameter
is the Typical value from Table 39 and Table 41.
