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. EMC Technical File (EMC TF) referenced ‘DSPTOOLS1’ dated

December 21, 1997 and was declared CE compliant by an appointed

Notified Body (No.0673) as listed below.

Notified Body Statement of Compliance: Z600ANA1.027

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.

PREFACE

Thank you for purchasing the ADSP-21375 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-21375 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-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

Access to the ADSP-21375 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-21375 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-21375 EZ-KIT Lite provides example programs to demon-

strate the capabilities of the evaluation board.

Product Overview

The board features:

• Analog Devices ADSP-21375 processor

• 208-pin MQFP package

• 266 MHz core clock speed

• Synchronous dynamic random access memory (SDRAM)

• 2M x 16-bit x 4 banks

Product Overview

xii ADSP-21375 EZ-KIT Lite Evaluation System Manual

• Expansion interface (type A)

• Parallel port, FLAG pins, DPI, DAI

• Other features

• JTAG ICE 14-pin header

• Test points for processor current measurement

• DPI header

• DAI header

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 standalone unit. For more informa-

tion, see “External Memory” on page 1-12 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 is connected to the AD1835A audio codec

and an external phase lock loop (PLL). The DAI interface facilitates devel-

opment of digital and analog audio signal-processing applications. See

“Analog Audio” on page 1-14 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, while the

SPI connects to the 2M bit 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.
