STANDBY consumption

This table shows modules consumption contributions in STANDBY mode:

So, the STANDBY lowest consumption is 21 µA obtained with following configuration:

–

PD0 conso = 0.2 mA

–

FIRC,SIRC,SRAM-24K off

On the other hand, maximum consumption (FIRC,SIRC,SRAM-24K on) is 314.8 µA.

Peripherals

In order to evaluate peripheral consumption contributions measured on ballast voltage

(IDD_BV), following table can be used that provides for all the main device peripherals,

either dynamic or static consumption.

Consumption of Power Domain 1 that depends on the system clock (divided or not) provided to the

peripherals
