SA9203/5

6/3 X 8 PORT EXPANDER

FEATURES

Six (SA9203) or three (SA9205) 8-Bit

I/O Ports

Readback of all control and port

registers

Interfaces directly with multiplexed

addressanddatabusmicroprocessors/

microcontrollers

Each bit of one port independently

programmable as input or output

Five (SA9203) or two (SA9205)

remaining ports can be individually

configuredasinputoroutput. (Direction

applicable to all 8 pins of each port.)

Internal address latch

Single +5V power supply

Low power CMOS

One 8-Bit port programmable as either

atched or transparent inputs

Completely static operation

TTL-level compatibility

Supports byte-wide and bit-wide I/O

port addressing modes on all ports

DESCRIPTION

The SAMES SA9203/5 Port Expander is a

CMOS device suited to microprocessor

based applications requiring input/output

port expansion. The device interfaces very

simply to any microcontroller/micro-

processor with amultiplexed address/data

bus structure.

The SA9203 includes 8 independently

programmable I/O pins for Port A and Port

BtoF(5ports)independentlyprogrammable

as I/O. It is packaged in a PCB efficient 68

pin PLCC package. The SA9205 includes

8 independently programmable I/O pins for

Port A with Port B and Port C as indepen-

dently programmable I/O, packaged in a

cost effective 44 pin PLCC package.
