Electrical characteristics STM32H743xI
108/226 DocID030538 Rev 3
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 startu
p, all I/O pins are in analog input configuration.
• All peripherals are disabled unless otherwise mentioned.
• The I/O compensation cell is enabled.
• f
ACLK
is the system clock. f
PCLK
= f
ACLK
/4, and f
HCLK
= f
ACLK
/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
ACLK
= 400 MHz (Scale 1), f
ACLK
= 300 MHz (Scale 2),
f
ACLK
= 200 MHz (Scale 3)
• The ambient operating temperature is 25 °C and V
DD
=3.3 V.
