Electrical Characteristics

DC Parameters for

Standard Voltage

TA = -40°C to +85°C; VSS = 0 V; VCC = 3 volts to 5.5 volts; F = 0 to 40 MHz

Notes:

1. Typicals are based on a limited number of samples and are not guaranteed. The values listed are at room temperature.

2. Flash retention is guaranteed with the same formula for VCC min down to 0V.

Absolute Maximum Ratings*

I = industrial ....................................................... -40°C to 85°C

Storage Temperature ................................... -65°C to + 150°C

Voltage on VCC from VSS .....................................-0.5V to + 6V

Voltage on Any Pin from VSS .....................-0.5V to VCC + 0.2V

Power Dissipation ............................................................. 1 W

*NOTICE:

Stresses at or above those listed under “Abso-

lute 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 above those indicated in the

operational sections of this specification is not

implied. Exposure to absolute maximum rating

conditions may affect device reliability.

Power Dissipation value is based on the maxi-

mum allowable die temperature and the thermal

resistance of the package.
