The EM6607 is a single chip low power, 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 EM6607 microcontroller is manufactured using EM's Advanced Low Power CMOS Process.
In 24 Pin package it is a direct replacement for EM6603.
