Regulatory Compliance
The ADSP-21369 EZ-KIT Lite is designed to be used solely in a labora-
tory environment. The board is not intended for use as a consumer end
product or as a portion of a consumer end product. The board is an open
system design which does not include a shielded enclosure and therefore
may cause interference to other electrical devices in close proximity. This
board should not be used in or near any medical equipment or RF devices.
The ADSP-21369 EZ-KIT Lite has been certified to comply with the
essential requirements of the European EMC directive 2004/108/EC and
therefore carries the “CE” mark.
The ADSP-21369 EZ-KIT Lite has been appended to Analog Devices,
Inc. EMC Technical File (EMC TF) referenced DSPTOOLS1, issue 2
dated June 4, 2008 and was declared CE compliant by an appointed
Notified Body (No.0673) as listed below.
Notified Body Statement of Compliance: Z600ANA1.025
Issued by: Technology International (Europe) Limited

Shrivenham, Swindon, SN6 8TY, UK
The EZ-KIT Lite evaluation system contains ESD (electrostatic discharge)
sensitive devices. Electrostatic charges readily accumulate on the human
body and equipment and can discharge without detection. Permanent
damage may occur on devices subjected to high-energy discharges. Proper
ESD precautions are recommended to avoid performance degradation or
loss of functionality. Store unused EZ-KIT Lite boards in the protective
shipping package.

ADSP-21369 EZ-KIT Lite Evaluation System Manual ix
PREFACE
Thank you for purchasing the ADSP-21369 EZ-KIT Lite®, Analog
Devices, Inc. evaluation system for SHARC®processors.
SHARC processors are based on a 32-bit super Harvard architecture that
includes a unique memory architecture comprised of two large on-chip,
dual-ported SRAM blocks coupled with a sophisticated I/O processor,
which gives a SHARC processor the bandwidth for sustained high-speed
computations. SHARC processors represents today’s de facto standard for
floating-point processing, targeted toward premium audio applications.
The evaluation system is designed to be used in conjunction with the
CrossCore®Embedded Studio (CCES) and VisualDSP++®development
environments to test capabilities of the ADSP-21369 SHARC processors.
The development environment aids advanced application code develop-
ment and debug, such as:
• Create, compile, assemble, and link application programs written
in C++, C, and ADSP-21369 assembly
• Load, run, step, halt, and set breakpoints in application programs
• Read and write data and program memory
• Read and write core and peripheral registers
• Plot memory
Access to the ADSP-21369 processor from a personal computer (PC) is
achieved through a USB port or an external JTAG emulator. The USB
interface provides unrestricted access to the ADSP-21369 processor and

evaluation board peripherals. Analog Devices JTAG emulators offer faster
communication between the host PC and target hardware. Analog Devices
carries a wide range of in-circuit emulation products. To learn more about
Analog Devices emulators and processor development tools, go to
http://www.analog.com/dsp/tools.
The ADSP-21369 EZ-KIT Lite provides example programs to demon-
strate the product capabilities.

Please visit www.analog.com/21369EZkit for additional information,
including CCES support.
The EZ-KIT Lite board has a total of 1 MB of parallel flash memory and
2M bit of SPI flash memory. Flash memories can store user-specific boot
code and allow the board to run as a stand-alone unit. For more informa-
tion, see “External Memory” on page 1-11 and “Boot Mode and Clock
Ratio Select Switch (SW2)” on page 2-10. The board also has 512 KB of
SRAM and 16 MB of SDRAM, which can be used at runtime.
The DAI port of the processor is connected to the AD1835A audio codec,
Sony/Philips Digital Interface (S/PDIF), and an external phase lock loop
(PLL). The DAI interface facilitates development of digital and analog
audio signal-processing applications. See “Analog Audio” on page 1-14
and “S/PDIF Coax Connectors (J7 and J8)” on page 2-24 for more
information.
The DPI port of the processor is connected to the UART and SPI inter-
faces. The UART interface can connect to a standard RS-232 connector,
while the SPI connects to 2M bit of serial flash memory.

Preface
Additionally, the EZ-KIT Lite board provides access to all of the proces-
sor’s peripheral ports. Access is provided in the form of a three-connector
expansion interface. See “Expansion Interface” on page 2-7 for details.
