13.4 SUPPLY CURRENT CHARACTERISTICS
The following current consumption specified for
the ST7 functional operating modes over tempera-
ture range does not take into account the clock
source current consumption. To get the total de-

Notes:
1. CPU running with memory access, all I/O pins in input mode with a static value at V
in reset state; clock input (CLKIN) driven by external square wave, LVD disabled.
2. All I/O pins in input mode with a static value at V
driven by external square wave, LVD disabled.
3. SLOW mode selected with f
V
4. SLOW-WAIT mode selected with f
V
5. All I/O pins in output mode with a static value at V
tested in production at V
6. All I/O pins in input mode with a static value at V
max.
7. This consumption refers to the Halt period only and not the associated run period which is software dependent.
