STM32WLE4 details incorrect - no LoRa?

On this page: https://www.st.com/en/microcontrollers-microprocessors/stm32wle4c8.html

The device is specified as having LoRa support in the first paragraph of the description but lower down in the "More from the product line" section the WLE4 chips are indicated not to include LoRa. Also the product selector filtering includes WLE4 devices when LoRa is filtered for.

The datasheet says: "The LoRa® modulation is available in STM32WLx5xx only." so I think the web site is incorrect?

Hello @robdobsn and welcome to the ST Community.

For the first paragraph is correct since it took about the STM32WLE5/4xx series and the STM32WLE5 MCUs does include the LoRa support. This is clarified on the next paragraph « The LoRa® modulation is available in STM32WLx5xx only. » 

For the product selector, it seems to be a problem that I've escalated to the concerned team for correction (under internal ticket number 205882).

 

PS: this has been solved on the version 6.15.0 of the STM32CubeMX.

Best Regards.

But the page is titled just STM32WLE4C8 - so why is it mentioning WLE5 at all ?

and elsewhere on the page states LoRa without qualifying it:

It all strikes of sloppy copy-pasting.

I'm sure this has come up before.

 

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.

I will escalate your opinion to the team @Andrew Neil  to request for a potential rectification.
