Regulatory Compliance
The Blackfin Landscape LCD EZ-Extender is designed to be used solely
in a laboratory environment. The board is not intended for use as a con-
sumer end product or as a portion of a consumer end product. The board
is an open system design which does not include a shielded enclosure and
therefore may cause interference to other electrical devices in close prox-
imity. This board should not be used in or near any medical equipment or
RF devices.
The Blackfin Landscape LCD EZ-Extender is currently being processed
for certification that it complies with the essential requirements of the
European EMC directive 89/336/EEC amended by 93/68/EEC and
therefore carries the “CE” mark.
The Blackfin Landscape LCD EZ-Extender contains ESD (electrostatic dis-
charge) sensitive devices. Electrostatic charges readily accumulate on the
human body and equipment and can discharge without detection. Perma-
nent damage may occur on devices subjected to high-energy discharges.
Proper ESD precautions are recommended to avoid performance degrada-
tion or loss of functionality. Store unused extender boards in the protective
shipping package.

PREFACE
Thank you for purchasing the Blackfin®Landscape LCD EZ-Extender®,
Analog Devices, Inc. extender board to the EZ-KIT Lite®/EZ-Board®
evaluation system for the ADSP-BF526, ADSP-BF537, ADSP-BF538,
and ADSP-BF548 Blackfin processors.
Blackfin processors are embedded processors that support a Media
Instruction Set Computing (MISC) architecture. This architecture is the
natural merging of RISC, media functions, and digital signal processing
characteristics towards delivering signal processing performance in a
microprocessor-like environment.
EZ-KIT Lites and Landscape LCD EZ-Extenders are designed to be used
in conjunction with the CrossCore®Embedded Studio (CCES) and Visu-
alDSP++®software development environments. The development
environment facilitates advanced application code development and
debug, such as:
• Create, compile, assemble, and link application programs written
in C++, C, and Landscape LCD EZ-Extender assembly
• Load, run, step, halt, and set breakpoints in application programs
• Read and write data and program memory
• Read and write core and peripheral registers
• Plot memory

Product Overview
x Blackfin Landscape LCD EZ-Extender Manual
Product Overview
The Blackfin Landscape LCD EZ-Extender is a separately sold daughter
board that plugs onto the expansion interface II of the ADSP-BF526
EZ-Board. The extender also plugs into the parallel peripheral interface
(PPI) connector of the ADSP-BF537, ADSP-BF538, or ADSP-BF548
EZ-KIT Lite evaluation system. The extender board aids the design and
prototyping phases of the ADSP-BF526, ADSP-BF537, ADSP-BF538, or
ADSP-BF548 processor targeted applications.
Please visit www.analog.com/EX2-LLCD for additional information, includ-
ing CCES support.
The board extends the capabilities of the evaluation system by providing a
connection between the PPI of the Blackfin processor and the on-board
3.5 in. LCD display. The serial peripheral interconnect (SPI) port and
TWI interface of the Blackfin processor are used to communicate to the
LCD display, AD7879 touch screen controller, AD7147 capacitive touch
controller, and the 2 KB serial ROM of the extender.
The following is a list of the Blackfin Landscape LCD EZ-Extender
interfaces.
• LCD display with touch capabilities:
• Sharp LQ035Q1DH02 3.5 in. LCD with resistive touch
• 320 (horizontal) x 240 (vertical) landscape
• 1.8V to 3.6V I/O operation
• LCD backlight
• LCD touch controller:
• Analog Devices AD7879 touchscreen controller
• 1.8V to 3.3V I/O operation
