EM73982
4-BIT MICROCONTROLLER
11.30.2001
GENERAL DESCRIPTION
EM73982 is an advanced single chip CMOS 4-bit 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. EM73982 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, EM73982 also have a sleep mode for power saving function.
EM73982 is suitable for appliaction in many fields, for example : family appliance, consumer products, hand
held games and the toy controller ... etc.
