STM32F405 vs STM32G4

STLearner · ‎2024-01-02

Hi ST experts,

Does STM32G4 series MCU support Vocoder feature? If yes, do you have any related documents available for reference? Current design is using STM32F405 which can support Vocoder application.

Thanks.

Hello @STLearner

As indicated in the AN4229:

"the vocal codecs (vocoder) available for STM32 32-bit ARM Cortex microcontrollers." That means you can use it with the STM32 MCUs.

For more details as indicated in the Application Note, i suggest you contact your local ST sales representative.

PS: The examples of implementation are developed in such a way that they can be easily ported to any other STM32 microcontroller and board.

Best Regards.

Both the 'F4 and 'G4 are based around the Cortex-M4 processor, and have similar maximum system clock, so it's quite likely that the algorithmic/computational part of the demo will work. What is different are the peripherals.

I would start with a "known good" hardware such as Nucleo or Disco (unfortunately, the newer families' Discos are not that useful as the older were), get the peripherals needed working, and proceed from that.

What's the motivation for using 'G4 instead of 'F4 in your application?
