Parameter interpretation

The parameters listed in the following tables represent the characteristics of the ST10F276

and its demands on the system.

Where the ST10F276 logic provides signals with their respective timing characteristics, the

symbol “CC” (Controller Characteristics) is included in the “Symbol” column. Where the

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

ST10F276, the symbol “SR” (System Requirement) is included in the “Symbol” column.
