NUCLEO-U575ZI-Q
NUU575ZIQ$AT1
MCU: STM32U575ZIT6Q silicon
revision "X"
Initial revision for Nucleo-144
embedded STM32U575ZIT6Q MCU
with a USB full-speed interface
Bootloader communication interfaces
are not available if TZEN=1.
When TrustZone
®
is enabled and
boot from system memory is
selected (BOOT0 = 1) to use
the bootloader, the ST embedded
bootloader is blocked, thus making
all the bootloader interfaces no more
usable (USB-DFU, USART, SPI, I
2
C,
and CAN FD). As a consequence,
the SFI (secure firmware install) using
bootloader communication interfaces
does not work, and the option
bytes cannot be changed using the
bootloader interface. SFI and option
bytes change using JTAG/SWD
interface remains functional.
There is no workaround
to this limitation solved in
the NUU575ZIQ$AT2 product
identification.

NUU575ZIQ$AT2
MCU: STM32U575ZIT6Q silicon
revision "X"
The bootloader revision embedded
on this STM32U575ZIT6Q integrates
the correction for the bootloader
communication interfaces when
TZEN=1.

NUCLEO-U5A5ZJ-Q
NUU5A5ZJQ$AT1
MCU: STM32U5A5ZJT6Q
silicon revision "C"
Initial revision for Nucleo‑144 embeds
the STM32U5A5ZJT6Q MCU with
USB high‑speed interface.
The STM32U5A5ZJT6Q silicon
revision “C” embedded on
the NUCLEO-U5A5ZJ-Q with
the NUU5A5ZJQ$AT1 product
identification does not support the
SFI.
This limitation is solved on
the NUU5A5ZJQ$AT2 product
identification.

MCU: STM32U5A5ZJT6Q
silicon revision "X"
The STM32U5A5ZJT6Q silicon
revision “X” embedded on NUCLEO-
U5A5ZJ-Q with the NUU5A5ZJQ$AT2
product identification supports the
SFI.
