Description

The EM6620 is an advanced single chip CMOS 4-

bit microcontroller. It contains ROM, RAM, power

on reset, watchdog timer,

oscillation detection

circuit, 10 bit up/down counter, Millisecond counter,

prescaler, voltage level detector (SVLD), compare

input, frequency output, LCD driver and several

clock functions. The low voltage feature and low

power consumption make it the most suitable

controller for battery, stand alone and mobile

equipment. The EM6620 is manufactured using EM

Microeletronic’s

Advanced
