ABSOLUTE MAXIMUM RATINGS

Stresses greater than those listed under Absolute Maximum

Ratings may cause permanent damage to the device. This

rating is a stress rating only. Functional operation of the de-

vice at any condition above those indicated in the opera-

tional sections of these specifications is not implied. Expo-

sure to absolute maximum rating conditions for an extended

period may affect device reliability.

Total power dissipation should not exceed 1.21 W for the

package. Power dissipation is calculated as follows:

Maximum Allowable Output Current Sourced by Any I/O Pin

Notes:

1. Applies to all pins except XTAL pins and where otherwise noted.

2. There is no input protection diode from pin to VDD and current into pin is limited to ±600 µA.

3. Excludes XTAL pins.

4. Device pin is not at an output Low state.

Total Power Dissipation = VDD x [IDD – (sum of IOH),

+ sum of [(VDD – VOH) x IOH]

+ sum of (VOL x IOL)
