T48C862-R4 [Preliminary]

4551C–4BMCU–01/04

Absolute Maximum Ratings: Microcontroller Block

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., V

DD).
