STM32WL33 specification

Hi,

I am looking to use the STM32WL33 in a product. 
I am curious as to what the chip is in terms of its silicon. Is the M0+ equivalent to an available MCU?
What is on the radio side? Is this an S2-LP for example?

Thanks

Hello,

regarding Radio IP, this is an evolution of S2-LP radio, but not the same.

let's say better performance/power consumption and new features. and if you are familiar with S2-LP you won't be lost

;)

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 links. The second one was very useful as it links to reference designs, which i was struggling to find.
    However. It doesnt answer my initial question.

    The reason i am asking is that this chip as far as i am aware is brand new. As such there isnt much info on it working besides some examples. 
    If it is based on an already existing radio, i.e the S2-LP then it may be a bit easier to work with.
    Many manufacturers do this. For example Texas Instruments uses the CC1101 Transceiver in most of their sub ghz SOC.

    Not just that, but i like to know what i am working with. If this is brand new silicon. It usually comes with issues.

    Hello @CEagl.1 

    Thank you so much @Andrew Neil for your contribution. to understand more about the STM32WL33 radio part, I suggest you take a look at the chapter 29 of RM0511.If you are looking for more specific details, you need to contact an FAE or one of our Sales & marketing teams. 

    Best Regards.
