I have design pcb for Stm32H723VGT6 ( 100 pins TQFP ) my job is read adc 12 bit and transfer over usb to PC . i have set sysclk to 550 MHz and ADC clock to 64 MHz so i got sample rate to 1.3 Msps but mcu are hot. So i have sysclk to 400 and ADC ...
Thank you this topic i have design my board with stm32H723 i need maximum adc speed so set clock to 550 Mhz but the chip is hot . i have down to 400 Mhz founded temperature cool down . but adc sample rate down too. why?
