www.DataSheet4U.com Preliminary W78IE52 8-BIT MICROCONTROLLER 1. GENERAL DESCRIPTION The W78IE52 is an 8-bit microcontroller which can accommodate a wider frequency range with low power consumption. The instruction set for the W78IE52 is fully compatible with the standard 8051. The W78IE52 contains an 8K bytes Flash EPROM; a 256 bytes RAM; four 8-bit bi-directional and bitaddressable I/O ports; an additional 4-bit I/O port P4; three 16-bit timer/counters; a hardware watchdog timer and a serial port. These peripherals are supported by eight sources two-level interrupt capability. To facilitate programming and verification, the Flash EPROM inside the W78IE52 allows the program memory to be programmed and read electronically.
