Making 32-bit capabilities accessible to all with the most affordable ST MCUs.

Expanding the STM32C0 portfolio, the newly introduced STM32C05 and STM32C09 product lines offer additional memory density alternatives, with the STM32C092 also featuring FDCAN connectivity. These microcontrollers provide up to 256 Kbytes of flash memory and 36 Kbytes of RAM, available in packages ranging from 20 to 64 pins. 

Additionally, the previously released STM32C071 includes USB connectivity for both host and device modes, eliminating the need for an external crystal.
