ADSP-2189M EZ-KIT Lite Evaluation System Manual vii
PREFACE
Thank you for purchasing the ADSP-2189M EZ-KIT Lite®, Analog
Devices (ADI) evaluation system for ADSP-2189 DSPs.
The ADSP-2189M DSP is a single-chip microcomputer optimized for
digital signal processing (DSP) and other high-speed numeric processing
applications.
The evaluation board is designed to be used in conjunction with
VisualDSP++™ development environment to test the capabilities of the
ADSP-2189M DSPs. The VisualDSP++ software 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-2189M 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
Using the EZ-KIT Lite with VisualDSP++, you can observe the
ADSP-2189M processor execute programs from on-chip RAM, interact
with on-board devices, and communicate with other peripherals located
on optional add-on modules.

viii ADSP-2189M EZ-KIT Lite Evaluation System Manual
You can access the ADSP-2189M processor from a personal computer
(PC) through a serial port or an optional emulator. The monitor program
gives you complete target debug capability through the serial port. In con-
trast, the emulator allows the PC to perform in-circuit emulation through
the processor’s emulation port.
The boards features:
• Analog Devices ADSP-2189MKST-300 processor
!Operating at an instruction rate of 75 MIPS (37.57 external
clock)
• Analog Audio Interface
!AD73322AR – Analog Devices stereo codec
• Analog Inputs
!One stereo pair of 2V RMS AC coupled line-level inputs
!One stereo pair of 20 mV RMS AC coupled microphone
inputs
• Analog Outputs
!One stereo pair of 1V RMS AC coupled line-level outputs
• Power Source
!7.5V DC (+ or -5%) at 4.0 Amps (maximum)
• Environment
!0 to 70ocentigrade
!10 to 90 percent relative humidity (non condensing)
• RS-232 Interface

Preface
• Flash memory
• User push buttons
• Prototype (expansion) area
• User configurable jumpers
The ADSP-2189M board is equipped with hardware that facilitates inter-
active demonstrations. Push button switches and user programmable
LEDs provide user control and board status checking. Additionally, the
AD73322 SoundPort codec provides access to an audio input (selectable
as line level or microphone) and an audio output (line level). To learn
more about AD73322 codec, see the data sheet at
http://www.analog.com/Uploaded-
Files/Data_Sheets/14950546AD73322_b.pdf.
The ADSP-2189MEZ-KIT Lite includes a monitor program stored in the
original Flash memory. The monitor program lets the board communicate
over the serial port to a PC. This monitor program lets you download,
execute, and debug ADSP-2189M programs.
You can also connect an EZ-ICE (in-circuit emulator) to the EZ-KIT
Lite. Through the EZ-ICE, you can load programs, start and stop pro-
gram execution, observe and alter registers and memory, and perform
other debugging operations. To learn more about Analog Devices emula-
tors and DSP development tools, go to
http://www.analog.com/dsp/tools/.
Additionally, the EZ-KIT Lite provides user installed expansion connec-
tors that let you examine processor signals, as well as provide an interface
for host control.
"The VisualDSP++ licence provided with this EZ-KIT Lite evalua-
tion system limits the size of a user program to 8K bytes of internal
memory.

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.
