ST10F272Z2
25.4
Table 63.
Based on thermal characteristics of the package and with reference to the power
consumption figures provided in next tables and diagrams, the following product
classification can be proposed. Anyhow, the exact power consumption of the device inside
the application must be computed according to different working conditions, thermal profiles,
real thermal resistance of the system (including printed circuit board or other substrata), I/O
activity, and so on.
Table 64.
Parameter interpretation
The parameters listed in the following tables represent the characteristics of the
ST10F272Z2 and its demands on the system.
Where the ST10F272Z2 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
ST10F272Z2, the symbol “SR” for System Requirement, is included in the “Symbol” column.
