SpecificationsVoltages are given relative to VSS.
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
All inputs and outputs are protected against high electrostatic voltages or electric fields. However, precautions to minimize the build-up of electrostatic charges during handling are recommended. Reliability of operation is enhanced if unused inputs are connected to an appropriate logic voltage level (e.g., VDD).

DescriptionThe 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 multifunction timer/counters with modulator and demodulator function, voltage supervisor, interval timer with watchdog function and a sophisticated on-chip clock generation with exter nal clock input , i ntegrated RC-, 32-kHz crystal - and 4-MHz crystal-oscillators.
