Applicability
This document applies to the part numbers of STM32L15xxE STM32L15xVD-X STM32L162xE STM32L162xVD-X devices and
the device variants as stated in this page.
It gives a summary and a description of the device errata, with respect to the device datasheet and reference manual RM0038.
Deviation of the real device behavior from the intended device behavior is considered to be a device limitation. Deviation of the
description in the reference manual or the datasheet from the intended device behavior is considered to be a documentation
erratum. The term
“errata” applies both to limitations and documentation errata.

1 Summary of device errata
The following table gives a quick reference to the STM32L15xxE STM32L15xVD-X STM32L162xE
STM32L162xVD-X device limitations and their status:
A = limitation present, workaround available
N = limitation present, no workaround available
P = limitation present, partial workaround available
“-” = limitation absent
Applicability of a workaround may depend on specific conditions of target application. Adoption of a workaround
may cause restrictions to target application. Workaround for a limitation is deemed partial if it only reduces the
rate of occurrence and/or consequences of the limitation, or if it is fully effective for only a subset of instances on
the device or in only a subset of operating modes, of the function concerned.
