13.4 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).

13.4.1 RUN, SLOW, WAIT and SLOW WAIT Modes

TA = -40 to +85°C unless otherwise specified

Notes:

1. Data based on characterization results, tested in production at VDD max. and fCPU max.

2. Program executed from RAM, 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 (OSC1) driven by external square wave, LVD disabled.

3. 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, LVD disabled.

4. Data based on characterization results, not tested in production.
