Does STM32L073RZT6 actually have "128‑bit AES hardware encryption"?

For example, Im looking at the STM32L073RZT6 

This documentation from ST states there is "128‑bit AES hardware encryption".

https://www.st.com/content/ccc/resource/sales_and_marketing/promotional_material/brochure/6c/48/c0/f1/bb/35/4a/b4/brstm32ulp.pdf/files/brstm32ulp.pdf/jcr:content/translations/en.brstm32ulp.pdf

But I can't find any reference on the datasheet

https://www.st.com/en/microcontrollers-microprocessors/stm32l073rz.html#resource

Is the first document to be trusted? whats going on??

Thanks

Any STM32L4 part withuneven decimal (L41, L43, L45, L47 ...) has Crypto disabled.

You want the STM32L083RZ part
