Dear ST-Team,

for our new project we plan to use STM32H743x. We plan to go into HW-Design Q4-2017

and start FW-Design end of 2017. Regarding this i have some questions with the useof the H7-Devices:

1. We want to buy a Nucleo-H743ZI. Which die revision are on these boards? Which limitation

does have the chip respectively which errata sheet revision is true?

2. Beside the core for our app the following peripheral components are importent:

- ETH (RMII)- I2C- RCC- SDMMC (SDIO 4Bits Wide Bus 50MHz)- SPI (Full Duplex Master)- SYS (SWD)- some Timers- USB-OTG-FS- USB-OTG-HS (with ULPI-Phy)Would you say it is uncritical to start HW- and FW-Design because end of 2017 there area H7-derivative on the market available, which fulfils a correct operation with all theseperipherals? And if yes, tell me please the chip part number.

Thanx in advance!!!

Regards

Dear ST-Team,

...

a H7-derivative on the market available, which fulfils a correct operation with all theseperipherals? And if yes, tell me please the chip part number.

There seems to be a small misunderstanding.

This is a public forum, with many volunteers not affiliated with ST (say, customers & users) - and some ST staff.

But I doubt ST will publish future plans here, or talk about silicon issues in depth ...

I suggest to contact a ST FAE, or a local distributor directly.

Hi

torsten.aurich

‌,

On current

, you will find a

rev. Y. So you can fully rely on the errata sheet

http://www.st.com/resource/en/errata_sheet/dm003684pdf

to understand its limitations.In this document, you will also be able to checkstatus of these limitations for next MCU revision.

About exact availability date of theserevisions,

meyer.frank

‌ is right, it is better to contactus through

. Nevertheless, I think that with the peripherals you have listed, you can start working with current revision: and if you want to access to SDMMC, ETH and USB OTG HS, you might as well use a

for development.

Best regards,
