Regulatory Compliance
The ADSP-21375 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-21375 EZ-KIT Lite has been certified to comply with the
essential requirements of the European EMC directive 89/336/EEC
amended by 93/68/EEC and therefore carries the “CE” mark.
The ADSP-21375 EZ-KIT Lite has been appended to Analog Devices,
Inc. Technical Construction File (TCF) referenced ‘DSPTOOLS1’ dated
December 21, 1997 and was awarded CE Certification by an appointed
European Competent Body as listed below.
Technical Certificate No: Z600ANA1.027
Issued by: Technology International (Europe) Limited
60 Shrivenham Hundred Business Park
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-21375 EZ-KIT Lite Evaluation System Manual ix
PREFACE
Thank you for purchasing the ADSP-21375 EZ-KIT Lite®, Analog
Devices, Inc. evaluation system for ADSP-21375 SHARC®processors.
The 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 IO pro-
cessor, 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
VisualDSP++®development environment to test the capabilities of the
ADSP-21375 SHARC processors. The VisualDSP++ development envi-
ronment gives you the ability to perform advanced application code
development and debug, such as:
• Create, compile, assemble, and link application programs written
in C++, C, and ADSP-21375 assembly
• Load, run, step, halt, and set breakpoints in application program
• Read and write data and program memory
• Read and write core and peripheral registers
• Plot memory

x ADSP-21375 EZ-KIT Lite Evaluation System Manual
Access to the ADSP-21375 processor from a personal computer (PC) is
achieved through a USB port or an optional JTAG emulator. The USB
interface gives unrestricted access to the ADSP-21375 processor and the
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/.
LThe ADSP-21375 EZ-KIT Lite installation is part of the Visu-
alDSP++ installation. The EZ-KIT Lite is a licensed product that
offers an unrestricted evaluation license for the first 90 days. For
details about evaluation license restrictions after the 90 days, refer
to “Evaluation License Restrictions” on page 1-7.
ADSP-21375 EZ-KIT Lite provides example programs to demonstrate the
capabilities of the evaluation board.
The board features:
• Analog Devices ADSP-21375 processor
D208-pin MQFP package
D266 MHz core clock speed
• Synchronous dynamic random access memory (SDRAM)
D2M x 16-bit x 4 banks

The EZ-KIT Lite board has a total of 1 MB of parallel flash memory and
2 Mbit of SPI flash memory. The flash memories can store user-specific
boot code, allowing the board to run as a stand-alone unit. For more
information, see “External Memory” on page 1-7 and “Boot Mode and
Clock Ratio Select Switch (SW2)” on page 2-10. The board has 16 MB of
SDRAM, which can be used at runtime or from which code can be
executed.
The DAI port of the processor connects to the AD1835A audio codec and
an external phase lock loop (PLL). The DAI interface facilitates develop-
ment of digital and analog audio signal-processing applications. See
“Analog Audio” on page 1-10 and for more information.
The DPI port of the processor connects to the UART interface and the
SPI interface. The UART interface can connect to a standard RS-232 con-
nection, while the SPI connects to the 2 Mbit of serial flash memory.
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.

Preface
Purpose of This Manual
The ADSP-21375 EZ-KIT Lite Evaluation System Manual provides
instructions for installing the product hardware (board) and describes the
operation and configuration of the board components. The product soft-
ware component is detailed in the VisualDSP++ Installation Quick
Reference Card. The manual provides guidelines for running your own
code on the ADSP-21375 EZ-KIT Lite. Finally, a schematic and a bill of
materials are provided as a reference for future designs.
Intended Audience
The primary audience for this manual is a programmer who is familiar
with Analog Devices processors. This manual assumes that the audience
has a working knowledge of the appropriate processor architecture and
instruction set. Programmers who are unfamiliar with Analog Devices
processors can use this manual but should supplement it with other texts,
such as the ADSP-2136x SHARC Processor Programming Reference and
ADSP-21368 SHARC Processor Hardware Reference (includes
ADSP-21375) that describe your target architecture.
Programmers who are unfamiliar with VisualDSP++ should refer to the
VisualDSP++ online Help and the VisualDSP++ user’s or getting started
guides. For the locations of these documents, see “Related Documents”.
