Is there any one who have official documents for STM32L072CBT6 Revision 1 and Revison P released for end-customer use?

[BTyle.1]

We received a batch of MCUs, STM32L072CBT6, LQFP48, on suffix of marking section has marked revision “1�?, marking on MCU are also marked with “1�?.

As per STM Errata sheet, there are different markings such as 1, P, Q, Z.

But I can only find related infos about revision Z in the STM Errata sheet, and cannot find any infos about revision “1�? from STM website.

Is there any one who knows how to find more details about Revision 1? 

Does STM have the official documents for Revision 1 and Revison P released for end-customer use ?

What are the full markings on the chip? Could relate to different masksets at different diffusion lines.​
