On-chip peripheral current consumption
The current consumption of the on-chip peripherals is given in
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
–
–
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, f

The typical values are obtained for V
specified.
