●

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.
