ELECTRICAL CHARACTERISTICS (cont’d)

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 obtain the total

device consumption, the two current values must

be added (except for HALT mode for which the

clock is stopped).

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 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.

6. 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.

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