Applicability
This document applies to the part numbers of STM32G471xx/473xx/474xx/483xx/484xx 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 RM0440.
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.

1Summary of device errata
The following table gives a quick reference to the STM32G471xx/473xx/474xx/483xx/484xx device limitations and
their status:
A = workaround available
N = no workaround available
P = partial workaround available
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.
