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
