Description
The EM6522 is an advanced single chip CMOS 4-
bit microcontroller. It contains EEPROM, 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 EM6522 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
