3.20

TSC interface

The STM32L0 series embeds enhanced version of touch sensing controller with full

hardware support. Therefore the firmware must be rewritten to support those new

architecture. The pinout compatibility for touch sensing channels was also partially changed

and there is need to change/review the application hardware design.

3.21

AES interface

The AES interface has not been changed in STM32L0 series, consequently it’s fully

compatible with STM32L1 version.
