On-chip peripheral current consumption

The current consumption of the on-chip peripherals is given in Table 26. The MCU is placed

under the following conditions:

•

At startup, all I/O pins are configured as analog inputs by firmware.

•

All peripherals are disabled unless otherwise mentioned

•

The given value is calculated by measuring the current consumption

–

with all peripherals clocked off

–

with one peripheral clocked on (with only the clock applied)

•

The code is running from Flash memory and the Flash memory access time is equal to

3 wait states at 120 MHz

•

Prefetch and Cache ON

•

When the peripherals are enabled, HCLK = 120MHz, fPCLK1 = fHCLK/4, and

fPCLK2 =fHCLK/2

•

The typical values are obtained for VDD = 3.3 V and TA= 25 °C, unless otherwise

specified.
