PREFACE
Thank you for purchasing the ADSP-21992 EZ-KIT Lite®evaluation sys-
tem. The evaluation board is designed to be used in conjunction with the
VisualDSP++ development environment to test the capabilities of the
ADSP-2199x fixed-point, mixed-signal, digital signal processor (DSP).
The VisualDSP++ development environment gives you the ability to perform
advanced application code development and debug tasks such as:
• Creating, compiling, assembling, and linking application programs
written in C++, C and, ADSP-21992 assembly
• Loading running, stepping, halting, and setting breakpoints in
application programs
• Reading and writing data memory and program memory
• Reading and writing core and peripheral registers
• Plotting memory
Access to the ADSP-21992 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-21992 processor and the
evaluation board peripherals. Analog Devices JTAG emulators provide the
fastest 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/

x ADSP-21992 EZ-KIT Lite Evaluation System Manual
ADSP-21992 EZ-KIT Lite provides example programs to demonstrate the
capabilities of the evaluation board.
!The VisualDSP++ license provided with this EZ-KIT Lite evalua-
tion system limits the size of a user program to 8K words of
internal memory.
The board’s features include:
• Analog Devices ADSP-21992 160 MHz, mixed-signal DSP
• USB debugging interface
• Analog input circuitry
• 8-channel 12-bit DAC (AD5328BRU) on SPI interface
• PWM outputs interface
• External memory interface
• Encoder interface circuitry
• General-purpose I/O interface
• UART interface (RS-232)
• CAN interface circuitry
• Flash memory (512K x 8)
• External SRAM (64K x 16)
• Interface connectors
• 14-pin emulator connector for JTAG interface
• Analog inputs connector
• DAC outputs connector

• Encoder interface connector
• SPORT connector
• RS-232 connector
• External memory interface connector
The EZ-KIT Lite board has a Flash memory device that can be used to
store user-specific boot code. You can configure a jumper (SW1 switch) and
program the Flash memory to run the board as a stand-alone unit. For
information about using the Flash memory, see “Using Flash Programmer
Utility” on page 2-6.
Additionally, the EZ-KIT Lite board provides un-installed expansion con-
nector footprints that allow you to connect to the processor’s External
Memory Interface (EMI).
Purpose of This Manual
The ADSP-21992 EZ-KIT Lite Evaluation System Manual provides
instructions for using the hardware and installing the software on your
PC. This manual provides guidelines for running your own code on the
ADSP-21992 EZ-KIT Lite. The manual also describes the operation and
configuration of the evaluation board’s components. Finally, a schematic
and a bill of materials are provided as a reference for future ADSP-21992
board designs.

Intended Audience
