Electrical characteristics

Typical current consumption

The MCU is placed under the following conditions:

•

VDD = VDDA = 1.8 V

•

All I/O pins are in analog input configuration

•

The Flash memory access time is adjusted to fHCLK frequency:

–

0 wait state and Prefetch OFF from 0 to 24 MHz

–

1 wait state and Prefetch ON above 24 MHz

•

When the peripherals are enabled, fPCLK = fHCLK

•

PLL is used for frequencies greater than 8 MHz

•

AHB prescaler of 2, 4, 8 and 16 is used for the frequencies 4 MHz, 2 MHz, 1 MHz and

500 kHz respectively
