Hello,

Availability requests should be asked over this link: https://ols.st.com/s/ or to contact your local distributor.

The alternative needs to be inline to what you need as features from that alternative MCU part number. You need to stay on the same family or you need to jump to whatever MCU having common features? 

Thank you.

looks like a STM32G473VETx would do same job as we are not using the high resolution timers at all - this sound correct? 

The application leans heavily on Large amount RAM, the ADC1,2,3,4,5 running at maximum speed with DMA triggered via TIM1 which also sends out an external clock at 2Mhz and clock phasing to trigger all ADC’s in parallel - also SP1 running as max speed for transfer on bus system. Normal USB and UART stuff apart from that.

Both devices share almost the same spec except the availability of HRTIM.

You can refer to the Table 2 “STM32G4xxx features and peripheral counts” in each datasheet and do the comparison:
