This errata sheet applies to the revision W of the STMicroelectronics STM32L151xx and STM32L152xx ultralow power products. This family features an ARM 32-bit Cortex®-M3 core, for which an errata notice is also available (see Section1 for details).

A full list of root part numbers is shown in Table1.

The products can be identified (see Table2) by:
