Product Summary
The ATAR892W is a 4-bit single-chip micro-controller. The device offers highest integration for IR and RF data communication, remote-control and phase-control applications. The ATAR892W is suitable for the transmitter side as well as the receiver side. The ATAR892W 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 sophisticated on-chip clock generation with external clock input, integrated RC-, 32-kHz crystal- and 4-MHz crystal-oscillators. The ATAR892W has an additional EEPROM as a second chip in one package.
