Description
The ATAR092-D is a member of Atmel’s family of 4-bit single-chip microcontrollers. It
offers the highest integration for IR and RF data communication, remote-control and
phase-control applications. The ATAR092-D is suitable as a transmitter as well as a
receiver. They contain ROM, RAM, parallel I/O ports, two 8-bit programmable multi-
function timer/counters with modulator and demodulator function, voltage supervisor,
interval timer with watchdog function and a sophisticated on-chip clock generation
