113 / 151 page  ST72F324L, ST72324BL 113/151 12.4 SUPPLY CURRENT CHARACTERISTICS The following current consumption specified for the ST7 functional operating modes over temperature range does not take into account the clock source current consumption. To get the total device consump- tion, the two current values must be added (except for HALT mode for which the clock is stopped). 12.4.1 CURRENT CONSUMPTION Notes: 1. Data based on characterization results, tested in production at VDD max. and fCPU max. 2. Measurements are done in the following conditions: - Progam executed from RAM, CPU running with RAM access. The increase in consumption when executing from Flash is 50%. - All I/O pins in input mode with a static value at VDD or VSS (no load) - All peripherals in reset state. - Clock input (OSC1) driven by external square wave. - In SLOW and SLOW WAIT mode, fCPU is based on fOSC divided by 32. To obtain the total current consumption of the device, add the clock source (Section 12.5.3) and the peripheral power consumption (Section 12.4.3). 3. All I/O pins in push-pull 0 mode (when applicable) with a static value at VDD or VSS (no load). Data based on charac- terization results, tested in production at VDD max. and fCPU max. 4. Data based on characterisation results, not tested in production. All I/O pins in push-pull 0 mode (when applicable) with a static value at VDD or VSS (no load); clock input (OSC1) driven by external square wave. To obtain the total current consumption of the device, add the clock source consumption (Section 12.5.3).
