Description
The EM66XX series is an advanced single
chip, mask programmed low-power low-voltage
CMOS 4-bit microcontroller. It contains ROM,
RAM, timer, prescaler, watchdog timer, voltage
level detector and stepper motor driver
capability. 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 (ALP) CMOS
Process.
Typical Applications
• sensor interfaces
• domestic appliances
• security systems
• detectors
• automotive control
• clocks
• measurement equipment
