W78C438C Overview
8-BIT MICROCONTROLLER The W78C438C is a high-performance single-chip CMOS 8-bit microcontroller that is a derivative of the W78C58 microcontroller family. The W78C438C is functionally patible with the W78C32, except that it provides either a 64 KB program/1 MB data memory address or memory-mapped chip select logic, five general I/O ports, and four external interrupts. In the W78C32, two I/O ports, Port 1 and Port 3,...
