Gigabit Ethernet device design and implementation

Hi all,

I would like to design a device with the following features:

  • Dual Gigabit ethernet,
  • Encrypted communication: SNMPv3, HTTPS, SMTPS.

I am looking for a SoC that makes it possible to achieve this functionality. After doing some research, I have found the STM32MP135F which seems to be able to achieve this functionality.

There is a development board of the mentioned SoC, but it has 2 ethernet ports that run only at 100Mb/s. Regarding the STM32MP135F datasheet, it is able to run two gigabit ports by having two RGMII interfaces.

My Concerns are:

1) Is it possible to run gigabit ethernet by using the STM32MP135F SoC?

2) If yes, then I am wondering if there is an easy way to test it?

3) Can I test the GbE link by using the STM32MP135F-DK board?

4) Are there other ICs (that would require less complicated design), that allow to achieve the same functionality?

Any help is apprecciated!

Dear @mmichala,

It's long time from post...

I do similar research for dual ethernet. After playing with STM32MP135F-DK board I summarize:

1) yes you can run 1gbit ethernet on STM32MP135F

2) you can test with NetX Duo API - but for 1Gbit you will need custom HW

3) STM32MP135F-DK board support only 100Mbit

4) I know that from STM is STM32MP13 only MPU which has dual Ethernet capability.

Hi @ravo 

You should build you own board or find a 3rd party STM32MP135F board providing dual gigabit ethernet, (there is no ST development board with dual Gigabit ethernet).


In addition, the brand new STM32MP25 could provide a 2 x Gigabit Ethernet GMAC and includes a internal Gigabit switch to achieve a total of 3 x Gigabit Ethernet ports.

All the ports provides also Time Sensitive Network (TSN) capabilities.

Last but not least, the STM32MP257F-EV1 board is providing all of this natively (prerelease board currently available under request thru https://www.mouser.fr/ProductDetail/STMicroelectronics/STM32MP257F-EV1?qs=ZcfC38r4PosgjLnr0guC7A%3D%3D).
You can see it in action here.
Please have a look to https://www.st.com/en/microcontrollers-microprocessors/stm32mp2-series.html

Full product availability is planned for end of June 2024.

Regards.
