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-

vice consumption, the two current values must be

added (except for HALT mode for which the clock

is stopped). Refer to Section 13.4.2 Internal RC

oscillator supply characteristics.

13.4.1 Supply Current

TA = -40 to +125°C unless otherwise specified

Notes:

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.

2. 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.

3. SLOW mode selected with fCPU based on fOSC divided by 32. 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.

4. SLOW-WAIT mode selected with fCPU based on fOSC divided by 32. 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.

5. All I/O pins in input mode with a static value at VDD or VSS (no load). Data tested in production at VDD max. and fCPU

max.

6. This consumption refers to the Halt period only and not the associated run period which is software dependent.

7. All I/O pins in output mode with a static value at VSS (no load), LVD disabled. Data based on characterization results,

tested in production at VDD max and fCPU max.

8. Data based on characterization, not tested in production.
