GENERAL DESCRIPTION
EM73A83 is an advanced single chip CMOS 4-bit micro-controller. It contains
16K-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. EM73A83 also
equipped with 6 interrupt sources, 3 I/O ports (including 1 input port and 2
bidirection ports), LCD display (40x16), built-in sound generator and speech
synthesizer.
Its low power consumption and high speed feature are further strengten with
DUAL, SLOW, IDLE and STOP operation mode for optimized power saving.
FEATURES
• Operation voltage : 2.2V to 4.8V.
