I'm working with this MCU in a project and ran out of flash space. Would like to know if there is a wat to add an external flash to this or if there is bigger flash option.

The STSPIN32F0 is based on the STM32F031C6, with the 32 KB flash already being the largest option. In addition to that it cannot be expanded externally due to the lack of an external bus interface. The STSPIN32F0 does contain an SPI interface, but it is neither suitable nor fast enough for executing code.

Have you already used the compiler option to improve optimization?
