STM32F42xx and STM32F43xx
Errata sheet
STM32F427/437 and STM32F429/439 line limitations
Silicon identification
This errata sheet applies to the revision A and Y of STMicroelectronics STM32F427/437
and STM32F429/439 microcontroller lines.
The STM32F42xx and STM32F43xx devices feature an ARM
®
32-bit Cortex™-M4 core with
FPU, for which an errata notice is also available (see Section 1 for details).
The full list of part numbers is shown in Table 2. The products are identifiable as shown in
Table 1:
• by the revision code marked below the order code on the device package
• by the last three digits of the Internal order code printed on the box label
Table 1. Device identification

1. The REV_ID bits in the DBGMCU_IDCODE register show the revision code of the device (see the RM0090
STM32F4xx reference manual for details on how to find the revision code).
