Description

The EM6821 is an advanced single chip low cost

CMOS 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 EM6821 is manufactured

using EM Microelectronic’a advanced low power

(ALP) CMOS process.

Typical

Applications

• Timing device

• Timer / sports timing devices

• Bicycle computers

• Measurement equipment

• Domestic appliance

• Interactive system with display

• Automotive controls with display

• Safety and security devices
