STM32H5E4/E5/F4/F5 with PLAY: boards availability?

waclawek.jan · ‎2026-02-27

A new STM32 sub-family (as part of the 'H5 family) came out. They have everything but the kitchen sink. As far as I can tell, 'H5E4 and 'H5E5 differ only in that the higher one has USB-HS with PHY (the 'H5Fx are crypto-enabled variants, as usually)

What's new is also the PLAY peripheral, which is a small programmable logic element, fully documented and configurable through registers. It's based around 16 simple logic elements (4-input LUT and an optional register), complete with an extensive input multiplexer matrix+filter, interconnected to a variety of peripherals (timers, DMA, ADC...) and also GPIO.

I wonder, if there's a Disco around...

There will be one Discovery board and one NUCLEO board ;).. Stay tuned.

You can use the latest version of CubeMx and use the board selector:

I don't see the PLAY mentioned on the STM32H5E4/5F4 or STM32H5E5/5F5 pages ?

PS:

But I do see it in DS14972 (STM32H5Fxxx) and RM0517 (STM32H5E4/5F4 and STM32H5E5/5F5), both at Rev 1.

Haven't checked any others yet ...

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

Thanks for the info, very interesting.

Just checking the RM.

Could be a few more gates and FFs for me to replace a Spartan 6 ... :D

But going into the right direction for my taste!

And an App Note ... ?

Of course like usual for any new STM32 series.. and a dedicated application note will be also available for PLAY.

Is there a simulator for this? I'd love to play with it without hardware.
I'd love to try to generate custom waveforms, hardware acceleration for certain operators, custom communication peripherals, etc.

Kudo posts if you have the same problem and kudo replies if the solution works.

It seems fairly simple - not sure it would warrant a simulator ... ?

That's not a true FPGA, CPLD or similar device. It's just a lookup table that you could construct some logic block with.
