Description The ATAR092-C and ATAR892-C are members of Atmel’s family of 4-bit single-chip microcontrollers. They offer the highest integration for IR and RF data communication, remote-control and phase-control applications. The ATAR092-C and ATAR892-C are suitable as transmitters as well as receivers. They contain ROM, RAM, parallel I/O ports, two 8-bit programmable multifunction timer/counters with modulator and www.DataSheet4U.com demodulator function, voltage supervision, 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-C has an additional EEPROM as a second chip in on...
