GENERAL DESCRIPTION

EM73C63 is an advanced single chip CMOS 4-bit micro-controller. It contains 32K-byte ROM, 500-nibble RAM, 4-bit ALU, 13-level subroutine nesting, 22-stage time base, two 12-bit timer/counters for the kernel function. EM73C63 is also equipped with 5 interrupt sources, 3 I/O ports (including 1 input port and 2 bidirection ports), LCD display (40x16), built-in sound generator.

Its low power consumption and high speed feature are further strengten with DUAL, SLOW, IDLE and STOP operation mode for optimized power saving.

FEATURES
