Regulatory Compliance
The ADSP-2191 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 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.

ADSP-2191 EZ-KIT Lite Evaluation System Manual ix
PREFACE
Thank you for purchasing the ADSP-2191 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-2191 fixed-point digital signal processor (DSP). The VisualDSP++
development environment gives you the ability to perform advanced applica-
tion code development and debug tasks such as:
• Create, compile, assemble, and link application programs written
in C++, C and ADSP-2191 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-2191 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-2191 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 DSP development tools, go to:
http://www.analog.com/dsp/tools/

x ADSP-2191 EZ-KIT Lite Evaluation System Manual
ADSP-2191 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-2191 processor
"160 MHz Core Clock Speed (default)
"Core Clock Multiplication Factor Selection Switch
• USB Debugging Interface
!This is not the DSP’s USB interface.
• Analog Devices AD1885 48 kHz AC’97 SoundMAX®Codec
"Jumper-Selectable Line-In or Mic-In 3.5 mm Stereo Jack
"Line-Out 3.5 mm Stereo Jack
• Analog Devices AD1803 Low-Power Modem Codec
"RJ-11 Telephone Line Connector
• Rx and Tx LEDs
• Flash Memory
"512K x 8
• Interface Connectors
"14-Pin Emulator Connector for JTAG Interface
"SPORT0 and SPORT1 Connectors
"External Memory Interface Connectors (not populated)
"Host Port Interface Connector (not populated)

Preface
• General-Purpose IO
"2 Push Button Inputs
"4 LEDs 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 (SW1 switch) and
by programming the Flash memory, the board can run as a stand-alone
unit. For information about using the Flash memory, see “Using Flash
Programmer Utility” on page 2-5.
SPORT0 is interfaced with an audio codec, allowing you to create audio sig-
nal processing applications.SPORT1 is connected to a telephony codec
allowing you to interface with a telephone line. Both SPORTs are attached to
off-board connectors to connect to 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
Memory Interface (EMI) and Host Port Interface (HPI).
Purpose of This Manual
The ADSP-2191 EZ-KIT Lite Evaluation System Manual provides instruc-
tions for using the hardware and installing the software on your PC. This
manual provides guidelines for running your own code on the
ADSP-2191 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-2191
board designs.
