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 a multiplexed address/data
bus structure.
The SA9203 includes 8 independently
programmable I/O pins for Port A and Port
B to F (5 ports) independently programmable
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.
