The 64-Mbit Q-SPI NOR Flash memory is connected to a Q-SPI interface of the STM32 device and can be used
to store graphic objects. The use of Q-SPI ensures optimum data transfer between the Flash memory and the
LCD display.
5.3.2Operating voltage
The NOR Flash memory is designed to operate only with a 3.3 V Q-SPI interface.
The stickers located on the top or bottom side of the PCB provide product information:
•Product order code and product identification for the first sticker
•Board reference with revision, and serial number for the second sticker
On the first sticker, the first line provides the product order code, and the second line the product identification.
On the second sticker, the first line has the following format: “MBxxxx-Variant-yzz”, where “MBxxxx” is the board
reference, “Variant” (optional) identifies the mounting variant when several exist, "y" is the PCB revision and "zz"
is the assembly revision, for example B01. The second line shows the board serial number used for traceability.
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 location is next to the evaluation tool ordering part number that is stuck or silk-screen printed
on the board.
