Description

The EM6520 is an advanced single chip CMOS 4-

bit microcontroller. It contains EEPROM, RAM,

power on reset, watchdog timer, oscillation

detection

circuit,

10

bit

up/down

counter,

Millisecond counter, prescaler, voltage level detec-

tor (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 EM6520 is manufactured

using EM Microelectronic’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
