SP1ML Microcontroller question

Good evening,

I have a question about the SP1ML module: it integrates Spirit1, baloon, chip antenna and the STM32L151RB microcontroller.

I search info about the STM32L151RB in yur site and I saw there are 2 version:

- STM32L151RB Not recommended for New Design. Product is in volume production only to support customers ongoing production.

- STM32L151RB-A Product is in volume production.

So my question is, what is the microcontroller version present in the module?

There is a longevity program for the module?

Thank you,

Silvio.
