Stresses greater than 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 any condition above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating condition for an extended period 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. V_DD).


Description

The M44C092 and M44C892 are members of TEMIC Semiconductors' family of 4-bit single-chip microcontrollers. They offer highest integration for IR and RF data communication, remote-control and phase-control applications. The M44C092 and M44C892are suitable for the transmitter side as well as the receiver side. It contains 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 M44C892 has an additional EEPROM as a second chip in one package.
