I recently noticed the STM32L family, while I already took a closer look at (and worked with) the STM32F family. At first glance it seemed to me that the STM32L05xxx are pin compatible with the STM32L05xxx. So here are my questions about compatibility:
- Are the STM32Lxxx pin compatible with STM32Fxxx? Also concerning things like 5V-tolerance on the pins, alternate functions?
- Are they software compatible, at least with minor changes (on the C-level not machine code level)?
- Is there a discovery kit for STM32L05xx that is compatible (ie replacable on my prototype base board) with STM32F0 discovery kit ?
- I read about these improvements: Cortex M0+ vs M0, true EEPROM. What others are there?
- Are there restrictions that could make a replacement impossible?
- Is there a paper summarizing all these things?
- Is there or will there be soon a support on CooCox?

Thanks a lot
