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 consumption, the two current values must be added.

Supply current in RUN mode(1)

1. CPU running with memory access, all I/O pins in input mode with a static value at VDD or VSS (no load),

all peripherals in reset state; clock input (CLKIN) driven by external square wave, LVD disabled.

VDD = 5.5 V, fCPU=8 MHz
