Is it possible to run the Matter stack on STM32WB55VGY7TR with an external 1Mbit QSPI flash and no other companion chip?

Hello PG1,

Yes it is possible to use STM32WB55 for Matter Over Thread End Device. In that case external Flash is required for OTA purposes. You can find an example of Matter Over Thread End Device in our wiki site (Go to Matter):

Category:Connectivity - stm32mcu

Also, if you are looking at making a Matter Device then please don't hesitate to contact our technical support team to get detailed information.

BR,

Anibal
