Semiconductor INPUT/OUTPUT PORT EXPANDER
This version: Jan. 1998 MSM82C43 Previous version: Nov. 1996
GENERAL DESCRIPTION
The MSM82C43 is an input/output port expander device based on CMOS technology and designed to operate at low power consumption levels. In systems employing the MSM80C48/49 8-bit single chip microcomputers, 4-bit data can be expanded by dividing between four I/O lines by executing the MOVDA, Pp, A and ORLDPp, A instructions.
FEATURES
* CMOS technology for low power consumption * 2.5 to 6 V single power supply (dependent on MSM80C48/49 operating frequency.) * Fully static operation * Bidirectional I/O ports * TTL coimpatible (ports 4 thru 7) * Functional compatiblity with Intel i8243 * Package options 24 pin Plastic DIP (DIP24-P-600-2.54) : (Product name : MSM82C43RS) 24 pin Plastic SOP (SOP24-P-430-1.27-K) : (Product name : MSM82C43GS-K)

PIN FUNCTIONS
Pin PROG CS P20 - P23 P40 - P43 P50 - P53 P60 - P63 P70 - P73 VCC GND Function Clock input from MSM80C49. When PROG is changed from "H" to "L", MSM82C43 STARTS operating in accordance with an order from MSM80C49. Input for chip select. Outputs and internal status cannot be changed when CS is "H". 4-bit bidirectional I/O ports. When connected to P20 thru P23 of MSM80C49, direct data transfer from port to accumulator and from accumulator to port is possible. 4-bit bidirectional I/O ports. Data is latched statistically when output to ports, but is only valid while PROG is at "L" level when input. +5V power supply GROUND
FUNCTIONS
Power-on reset mode Upon powered on, ports to 7 are 3-stated, and 2 is put into an input mode. Write mode Execution of MOVDPp, A, ORLDPp, A, ANLDPp, and A by MSM80C49 enables direct output of accumulator contents to ports 4 thru 7, and output to the ports after ORing or ANDing with port data. The port data is latched statistically at this time and remains unchanged until execution of the next instruction. Read mode Execution of MOVDA andPp results in data of ports 4 thru 7 being accepted by the accmulator. Note that port data is valid only while PROG is at "L" level. When at "H" level, ports 4 thru 7 are switched to tristate and port 2 is switched to input mode. Address and instruction code

Notes for Mounting the Surface Mount Type Package The SOP, QFP, TSOP, SOJ, QFJ (PLCC), SHP and BGA are surface mount type packages, which are very susceptible to heat in reflow mounting and humidity absorbed in storage. Therefore, before you perform reflow mounting, contact Oki's responsible sales person for the product name, package name, pin number, package code and desired mounting conditions (reflow method, temperature and times).
