Description
The EM66XX series is an advanced single chip low
cost, mask programmed CMOS 4-bit microcontroller.
It contains ROM, RAM, watchdog timer, oscillation
detection circuit, combined timer / event counter,
prescaler, voltage level detector and a number of
clock functions. Its low voltage and low power
operation make it the most suitable controller for
battery, stand alone and mobile equipment. The
EM66XX series is manufactured using EM’s
Advanced Low Power CMOS Process.
Typical Applications
sensor interfaces
domestic appliances
security systems
automotive controls
TV & audio remote controls
measurement equipment
R/F and IR. control
