AT/T89C51CC02

4126J–CAN–05/06

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.

3. Under steady state (non-transient) conditions, I

OL must be externally limited as follows:

Maximum I

OL per port pin: 10 mA

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

Note:

Stresses at or above 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 condi-

tions 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 maximum

allowable die temperature and the thermal resistance

of the package.
