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).

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)
