Description
The EM6622 is an advanced single chip low cost
CMOS 4-bit microcontroller. It contains ROM, RAM,
LCD driver, power on reset, watchdog timer,
oscillation detection circuit, 10-bit up/down and
event counter, 1ms BCD counter, prescaler, voltage
level detector (Vld), serial interface 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 EM6622 is manufactured using EM
Microelectronic's advanced low power (ALP) CMOS
process.
Typical
Applications
• Timing device
• Automotive controls with display
• Intelligent display driver
• Measurement equipment
• Domestic appliance
• Interactive system with display
• Timer / sports timing devices
• Bicycle computers
• Safety and security devices
