2.0 ELECTRICAL CHARACTERISTICS

Absolute Maximum Ratings

(†)

Ambient temperature under bias.............................................................................................................-40°C to +125°C

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

Voltage on V

DD with respect to VSS ......................................................................................................... -0.3V to +7.0V

Voltage on RESET

with respect to VSS ..................................................................................................... -0.3V to +14V

Voltage on all other pins with respect to V

SS (except VDDand GPIOA/B) ...................................... -0.6V to (VDD + 0.6V)

Voltage on GPIO Pins: ................................................................................................................................. -0.6V to 5.5V

Total power dissipation (Note 1)...........................................................................................................................700 mW

Maximum current out of V

SS pin ...........................................................................................................................400 mA

Maximum current into V

DD pin ..............................................................................................................................125 mA

Input clamp current, I

IK (VI < 0 or VI > VDD)...................................................................................................................... ±20 mA

Output clamp current, I

OK (VO < 0 or VO > VDD) .............................................................................................................. ±20 mA

Maximum output current sunk by any Output pin....................................................................................................25 mA

Maximum output current sunk by any Output pin (V

DD = 1.8V)..............................................................................10 mA

Maximum output current sourced by any Output pin ..............................................................................................25 mA

Maximum output current sourced by any Output pin (V

DD = 1.8V).........................................................................10 mA

Note: Power dissipation is calculated as follows:

Pdis = V

DD x {IDD - ∑ IOH} + ∑ {(VDD-VOH) x IOH} + ∑(VOL x IOL)

NOTICE: Stresses 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 those or any other conditions above those

indicated in the operation listings of this specification is not implied. Exposure to maximum rating conditions for

extended periods may affect device reliability.
