On-chip peripheral current consumption
The current consumption of the on-chip peripherals is given in Table 19. The MCU is placed
under the following conditions:
all I/O pins are in input mode with a static value at VDD or VSS (no load)
all peripherals are disabled unless otherwise mentioned
the given value is calculated by measuring the current consumption
–
with all peripherals clocked off
–
with only one peripheral clocked on
ambient operating temperature and VDD supply voltage conditions summarized in
Table 6
Table 19. Peripheral current consumption(1)
1. fHCLK = 72 MHz, fAPB1 = fHCLK/2, fAPB2 = fHCLK, default prescaler value for each peripheral.
