13. Description

The ATAR862-8 is a member of Atmel’s family of 4-bit single-chip microcontrollers. The

ATAR862-8 is suitable for the transmitter side as well as the receiver side. It contains ROM,

RAM, parallel I/O ports, two 8-bit programmable multifunction timer/counters with modulator and

demodulator function, voltage supervisor, interval timer with watchdog function and a sophisti-

cated on-chip clock generation with external clock input, integrated RC-oscillator, 32-kHz and

4-MHz crystal-oscillators. The ATAR862-8 has an EEPROM as a third chip in one package.
