Regulatory Compliance
The ADSP-21161N EZ-KIT Lite evaluation system has been certified to
comply with the essential requirements of the European EMC directive
89/336/EEC (inclusive 93/68/EEC) and, therefore, carries the “CE”
mark.
The ADSP-21161N EZ-KIT Lite evaluation system had been appended to
Analog Devices Development Tools Technical Construction File refer-
enced “DSPTOOLS1” dated December 21, 1997 and was awarded CE
Certification by an appointed European Competent Body and is on file.
The EZ-KIT Lite evaluation system contains ESD
(electrostatic discharge) sensitive devices. Electro-
static 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-21161N EZ-KIT Lite®, Analog
Devices, Inc. evaluation system for SHARC®digital signal processors
(DSPs).
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 processor,
which gives a SHARC processor the bandwidth for sustained high-speed
computations. SHARC processors represent today’s de facto standard for
floating-point processor targeted for premium audio applications.
The evaluation system is designed to be used in conjunction with the
VisualDSP++®development environment to test the capabilities of
ADSP-21161N 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-21161N 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

xii ADSP-21161N EZ-KIT Lite Evaluation System Manual
Access to the ADSP-21161N processor from a personal computer (PC) is
achieved through a USB port or an optional JTAG emulator. The USB
interface provides unrestricted access to the ADSP-21161N 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/.
The ADSP-21161N EZ-KIT Lite provides example programs to demon-
strate the capabilities of the evaluation board.
LThe ADSP-21161N 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.

• Analog Devices ADSP-21161N SHARC processor
D100 MHz core clock speed
DConfigurable core clock switch
• Analog Devices AD1836 96 kHz audio codec

The EZ-KIT Lite board has a flash memory device that can be used to
store user-specific boot code. By configuring the switch for EPROM boot,
the board can run as a stand-alone unit. The ADSP-21161N EZ-KIT Lite
package contains a flash programmer utility, which allows you to program
the flash memory. The “Flash Programmer Utility” is described
on page 1-13.

Purpose of This Manual
xiv ADSP-21161N EZ-KIT Lite Evaluation System Manual
SPORT0 and SPORT2 connect to the audio codec, facilitating creation of
audio-signal processing applications. SPORT1 and SPORT3 connect to
off-board connectors of other serial devices.
Additionally, the EZ-KIT Lite board provides un-installed expansion con-
nector footprints to connect to the processor’s external port (EP) and host
processor interface (HPI).
Purpose of This Manual
The ADSP-21161N 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-21161N 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-21161 SHARC Processor Hardware Reference and
ADSP-21160 SHARC Processor Instruction Set Reference) 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” on
page -xviii.
