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 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 M44C260 and M48C260 are members of the TEMIC family of 4-bit single chip microcontrollers. The M48C260 is the user programmable version of the M44C260. It contains an EEPROM program memory instead of a ROM. Both microcontroller types contain RAM, EEPROM data memory, parallel I/O ports, one timer with watchdog function, two 8/16-bit multifunction timer/counter and the on-chip clock generation.
