PREFACE
Thank you for purchasing the ADSP-21161N EZ-KIT Lite®, Analog
Devices (ADI) evaluation system for 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 SHARC the bandwidth for sustained high-speed
computations. SHARC represents today’s de facto standard for float-
ing-point DSP 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 the
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 program
• Read and write data and program memory
• Read and write core and peripheral registers
• Plot memory
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 gives unrestricted access to the ADSP-21161N processor and the

xii ADSP-21161N EZ-KIT Lite Evaluation System Manual
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 DSP development tools, go to
http://www.analog.com/dsp/tools/.
ADSP-21161N EZ-KIT Lite provides example programs to demonstrate
the capabilities of the evaluation board.
LThe VisualDSP++ license provided with this EZ-KIT Lite evalua-
tion system limits the size of a user program to 5K words of
internal memory.
The board features:
• Analog Devices ADSP-21161N processor
D100 MHz Core Clock Speed
DCore Clock Mode Jumper Configurable
• Analog Devices AD1836 96 kHz Audio Codec
DJumper Selectable Line-In or Mic-In 3.5 mm Stereo Jack
DLine-Out 3.5 mm Stereo Jack
D4 RCA Jacks for Audio Input
D8 RCA Jacks for Audio Output
• Analog Devices AD1852 192 kHz Auxiliary DAC
• Crystal Semiconductor CS8414 96 kHz SPDIF Receiver
DOptical and Coaxial Connectors for SPDIF Input
• Flash Memory
D512K x 8-bits

D6 LED Outputs
• Analog Devices ADP3338 and ADP3339 Voltage Regulators
• Breadboard area with typical SMT footprints
The EZ-KIT Lite board has a Flash memory device that can be used to
store user-specific boot code. By configuring the jumpers 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 “Using Flash Programmer Utility”
is described on page 2-8.
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 that allow you to connect to the processor’s External
Port (EP) and Host Processor Interface (HPI).
