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 (except for Halt mode

for which the clock is stopped).

Table 93.

IDD

Supply current in Run mode

fCPU = 8 MHz

(2)

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.

8.5

Supply current in Wait mode

fCPU = 8 MHz

(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.

3.7

Supply current in Slow mode

fCPU = 250 kHz

(4)

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 (OSC1) driven by external square wave,

LVD disabled.

4.1

Supply current in Slow-wait

mode

fCPU = 250 kHz

(5)

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 (OSC1) driven by external square

wave, LVD disabled.

2.2

3.5

Supply current in Halt mode (6)

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.

-40°C

Supply current in AWUFH

mode (7)(8)

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.

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

dependent.

TA= +25 °C

Supply current in Active-halt

mode (6)(7)

TA= +25 °C
