Description

Figure 2. Pin Configuration, TQFP64 10 * 10 * 1 mm

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
