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
