Hi,

    I am newbie to STM32 controllers.I have to select controller as per following spects.

1.Ethernet interface.

2.USB interface 4G module

3.SD card SPI interface.

4.UART interface.

6.i2c interface.

I need to get data from ethernet TCP.and store it on SD card and send it over USB-CDC(having 4 virtual com ports-AT command port and NMEA port are to be used in my application simultaneously).I want overall speed to be 1.5-2 Megabytes per sec(ethernet to USB speed)

Please suggest me any controller.

 I have selected this controller.

STM32F765ZGT6 216 MHZ freq

It will be good to select controller having max operating frequency near to 500MHZ.

Regards,

Akshay.

Hello,

I recommend you to use the 'MCU Finder' tool:

http://www.st.com/en/development-tools/st-mcu-finder.html?sc=stmcufinder

application (mobile version, PC version or the one embedded in STM32CubeMX) it will help you to find the product that will fit your needs.Regards

I can only find MCU from this application but will not get to know what will be approx ethernet and USB speed.

You might want to look into the datasheets of possible devices.

No one else here will take the blame for a wrong decision of yours.

Ask a tutor/colleague about your ideas and choices.

Well, the Cortex M world is not quite there, performance-wise.

Other vendors have higher clocked M7 devices, but are heavily engaged in merger&acquisition battles, with unknown prospective for their MCU portfolio.

Perhaps a Cortex A5 as alternative ?
