Nucleo board for STM32F373

[NJasa.1]

Hi,

Is nucleo board available for STM32F373 device? If not then any nucleo board can replace device with STM32F373?

There is no ST Demo board for the F373. I feel the SDADC of the F373 is not usefull, as the ADC gain is very variable. Consider e.g. some L4 with oversampling mode. It is a newer chips with many advantages as the peripherals are newer and more RAM

Thanks Uwe Bonnes,

In my application i have to measure three phase voltage and current measurements and i feel Sigma-Delta will give accurate measurement, that is why i select F373, again i will check L4, meantime can you please tell me that L4 can use for three phase voltage and current measurement?

Some L4 have a Sigma/Delta Interface too, see https://www.st.com/en/microcontrollers-microprocessors/stm32l4-series.html. Before you start with the F373 SDADC, have a look at the Gain error specifcation: -2.4 ..-2.7 ..-3.1%. Without a multiplexer to calibrate the gain you will be far off.

In addition the basic SAR 12-bit ADC on L4 has an up to 256x hardware oversampling with internal 20-bit summing and up to 16-bit data output.

Thanks Uwe Bonnes,

I have go through L4 devices and its seems to be applicable to my application. I will try on that. i am little bit greed, is any L4 device having Ethernet MAC10/100?
