CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the

device at these or any other conditions above those indicated in the operational sections of this specification is not implied.

NOTE:

1. θJA is measured with the component mounted on an evaluation PC board in free air.

NOTES:

2. No internal current limiting exists on Port Outputs. A resistor must be added externally to limit the current.

3. ICCOP = 1mA/MHz of Peripheral Read/Write cycle time. (Example: 1.0μs I/O Read/Write cycle time = 1mA).

4. Tested as VOH at -2.5mA.
