GENERAL DESCRIPTION

EM73P982 is an advanced single chip CMOS 4-bit one-time programming (OTP) micro-controller. It contains

16K-byte ROM, 372-nibble RAM, 4-bit ALU, 13-level subroutine nesting, 22-stage time base, two 12-bit timer/

counters for the kernal function. EM73P982 also contains 5 interrupt sources, 3 I/O ports (including 1 input port

and 2 bidirection ports), LCD display (40x8), built-in sound generator and speech synthesizer.

Except low-power consumption and high speed, EM73P982 also have a sleep mode for power saving function.

EM73P982 is suitable for appliaction in many fields, for example : family appliance, consumer products, hand

held games and the toy controller ... etc.
