NUCLEO-U575ZI-Q board information
8.1
Product marking
Evaluation tools marked as “ES” or “E” are not yet qualified and therefore not ready to be used as reference
design or in production. Any consequences deriving from such usage will not be at ST charge. In no event, ST will
be liable for any customer usage of these engineering sample tools as reference designs or in production.
“E” or “ES” marking examples of location:
•
On the targeted STM32 that is soldered on the board (For an illustration of STM32 marking, refer to the
STM32 datasheet “Package information” paragraph at the
•
Next to the evaluation tool ordering part number that is stuck or silk-screen printed on the board.
Some boards feature a specific STM32 device version, which allows the operation of any bundled commercial
stack/library available. This STM32 device shows a "U" marking option at the end of the standard part number
and is not available for sales.
In order to use the same commercial stack in his application, a developer may need to purchase a part number
specific to this stack/library. The price of those part numbers includes the stack/library royalties.

NUCLEO-U575ZI-Q product history
There is one generic identification associated with the Nucleo for STM32U5, PCB MB1549:
•
NUU575ZIQ$xxx for products without socket and with MCU soldered
8.2.1
Product identification NUU575ZIQ$AT1
This product identification is based on the NUCLEO-U575ZI-Q revision C02.
It embeds the
module with revision code "X". The limitations of this revision are detailed in the
errata sheet
STM32U575xx and STM32585xx device errata
Product limitation
Bootloader communication interfaces are not available if TZEN=1.
When TrustZone
®
is enabled and boot from system memory is selected (BOOT0 = 1) to use the bootloader,
the ST embedded bootloader is blocked, thus making all the bootloader interfaces no more usable (USB-
DFU, USART, SPI, I2C and FDCAN). As a consequence, the SFI (secure firmware install) using bootloader
communication interfaces does not work, and the option bytes cannot be changed using the bootloader interface.
SFI and option bytes change using JTAG/SWD interface remains functional.
Proposed workaround
None.
This limitation is solved in product identification NUU575ZIQ$AT2
8.2.2
Product identification NUU575ZIQ$AT2
This product identification is based on the NUCLEO-U575ZI-Q revision C02.
It embeds the
module with revision code "X". The limitations of this revision are detailed in the
errata sheet
STM32U575xx and STM32585xx device errata
The bootloader revision embedded on this STM32U575ZIT6Q integrates the correction for the bootloader
communication interfaces when TZEN=1.
Product limitation
No limitation identified for this product identification.
