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
Low
Power
(ALP)
CMOS Process.
Typical Applications
• Timing device
• Medical applications
• Domestic appliance
• Timer / sports timing devices
• Safety and security devices
• Automotive controls with display
• Measurement equipment
• Interactive system with display
• Bicycle computers
