Electrical characteristics STM32H743xI
110/231 DS12110 Rev 5
The test pin is configured in push-pull output mode and is toggled by software at a fixed
frequency.
On-chip peripheral current consumption
The MCU is placed under the following conditions:
 At st
artup, all I/O pins are in analog input configuration.
 All peripherals are disabled unless otherwise mentioned.
 The I/O compensation cell is enabled.
 f
rcc_c_ck
is the CPU clock. f
PCLK
= f
rcc_c_ck
/4, and f
HCLK
= f
rcc_c_ck
/2.
The given value is calculated by measuring the difference of current consumption
– with all peripherals clocked off
– with only one peripheral clocked on
–f
rcc_c_ck
= 400 MHz (Scale 1), f
rcc_c_ck
= 300 MHz (Scale 2), 
f
rcc_c_ck
= 200 MHz (Scale 3)
 The ambient operating temperature is 25 °C and V
DD
=3.3 V.
