Hi
When STM32L4 Plus series will be available to buy?
Any datasheets yet?

Hello,
Thanks for your interest on our future STM32 products.
It will be announced and available mid of November.
If you need to know more in between I suggest you to contact your STMicroelectronics contact or distributor.
Regards,

stcube already provides device headers. With a 'diff' you can see the differences...

Found some info about it at the end of this presentation:

Current L4 parts run north of 150 MHz, 120 MHz is hardly a stretch...

Current L4 parts run north of 150 MHz
Which?

On the bench the L476RG topped out at 158 MHz, the L496ZG somewhat below, they both perform solidly at 140 MHz.
Both have 3-bit wait state counter, so primary constraint is ART/prefetch path.
The 120 MHz number is probably with 60 MHz APB

They may be artificially underrated by ST to create room for step-up, or because testing for higher frequencies might be too expensive, or any other reason - but I tend to stick to the DS values for the stuff we sell.

No doubt, this was more of an intellectual exercise to see how much headroom there was in the design. Figuring more advantageous design than the original F2/F4, better process, and peripheral buses now running at 100-108 MHz in some of the designs.
The Cortex-M0(+) parts can also run faster than advertised, but with limited flash wait state options, pll settings, and no cache/prefetch as speed ramps above 28 MHz the speed of the flash becomes dominant.
