STM32G0x1 USB?

[waclawek.jan]

https://www.st.com/en/microcontrollers/stm32g0-series.html?icmp=tt9016_gl_****_dec2018&querycriteria=productId=SS1960 :

but on https://www.st.com/content/st_com/en/products/microcontrollers/stm32-32-bit-arm-cortex-mcus/stm32-mainstream-mcus/stm32g0-series/stm32g0x1.html?querycriteria=productId=LN2048 there is no mention of USB HOST/DEV, not even in the future products.

Is this some oversight, or are 'G0x3 with USB planned?

PS. Can that picture on website be provided in higher resolution, please?

The G0 series looks like an overhaul of F0. STM32F071 also has no USB, only F072 has. Hopefully a G072 is planned. I Expect the mention of USB on G071 is an error.

Hello,

USB HOST/DEV is not supported yet, but the part number supporting it will arrive rapidly.

Kind Regards,

Thanks, Imen, for the info.

OK. IT's been a year... "Can I has USB?"

Still no G0x3 with any USB?

[Imen.D]

Hi @kyrreaa​ ,

It is in development, target end of next year in mass production.

Best Regards,

So when you said "the part number supporting it will arrive rapidly", you meant 2 years?

​Hi, the USB is planned in the G0 series by Q2 next year. If you need both USB PD and USB data in your design, I suggest you to have a look on the STM32G4x1 value line series that support those functionalities. Best regards.

Thank you

Its strange. For the G071 it doesn't show USB in the data sheet. But the reference manual _still_ has a section for USB even though this MCU does not have this feature.

Hi Jean-Philippe @JDUMA​  ,

Thanks for the info.

The G4x1 have only USB Device. As shown in initial post, the G0 is promised to have HOST/DEV, is that true? If so, will it be again the Synopsys OTG, or something different?

Thanks,

Jan

​Hello

please have a look on the STM32G4 datasheet . It has both USB 2.0 FS data interface and USB PD.

here an extract of the STM32G431x Datasheet. BR, JP​

@JDUMA​ ,

I am not talking about PD, it's completely separate from the USB data transfer.

What I am talking about is the USB "data" module. In G4, it is Device only:

but look at the initial post here, it says DEV/HOST, indicating, that G0 might have a USB module capable of being either USB Device or USB Host.

Is this the case, or is that picture a blunder?

​Yes that's correct (as this is shown in the portfolio overview), new STM32G0Cx are planned by next year with a USB device / host comm interface. Switching from device to host or vice versa will be possible by using "data swap" command encapsulated in the USB PD protocol. BR, JP
