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

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
