Electrical characteristics

20.1

Absolute maximum ratings

Stresses the device above the rating listed in the Table 41: 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 conditions above those indicated in the operational

sections of this specification is not implied. Exposure to absolute maximum rating conditions

for extended periods may affect device reliability. During overload conditions (VIN > VDD or

VIN < VSS) the voltage on pins with respect to ground (VSS) must not exceed the values

defined Table 41.

20.2

Parameter interpretation

The parameters listed in the following tables represent the characteristics of the ST10F280

and its demands on the system. Where the ST10F280 logic provides signals with their

respective timing characteristics, the symbol “CC” for Controller Characteristics, is included

in the “Symbol” column.

Where the external system must provide signals with their respective timing characteristics

to the ST10F280, the symbol “SR” for System Requirement, is included in the “Symbol”

column.
