Description

Communication

The ATAR090 and ATAR890 are members of Atmel’s family of 4-bit single-chip micro-

controllers. They offer the highest integration for IR and RF data communication and

remote-control. The ATAR090 and ATAR890 are suitable for the transmitter side. They

contain 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 sophisticated on-chip clock generation with exter-

nal clock input, integrated RC-, 32-kHz crystal- and 4-MHz crystal-oscillators. The

ATAR890 has an additional EEPROM as a second chip in one package.
