Overview
NEe Microcomputers, Inc.
INPUT/OUTPUT EXPANDER FOR fLP 08048/8748/8035 NEe f'PD8243 DEseR IPTION The IlPD8243 input/output expander is directly compatible with the IlPD8048 family of single-chip microcomputers.
Using NMOS technology the IlPD8243 provides high drive capabilities while requiring only a single +5V supply voltage.
The IlPD8243 interfaces to the IlPD8048 family through a 4-bit I/O port and offers four 4-bit bi-directional static I/O ports.
The ease of expansion allows for multiple IlPD8243's to be added using the bus port.
The bi-directional I/O ports of the IlPD8243 act as an extension of the I/O capabilities of the IlPD8048 microcomputer family.
They are accessible with their own ANL, MOV, and OR L instructions.
FEATURES • Four 4-8it I/O Ports • Fu.
lly Compatible with IlPD8048 Microcomputer Family • High Output Drive • NMOS Technology • Single +5V Supply • Direct Extension of Resident IlPD8048 I/O Ports • Logical AND and OR Directly to Ports • Compa...
