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  
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 one package.
