The ATAR092 and ATAR892 are members of Atmel's family of 4-bit single-chip microcontrollers. They offer highest integration for IR and RF data communication, remotecontrol and phase-control applications. The ATAR092 and ATAR892 are suitable for the transmitter side as well as the receiver 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 external clock input, integrated RC-, 32-kHz crystal- and 4-MHz crystal-oscillators. The ATAR892 has an additional EEPROM as a second chip in one package. |
