What this STM32F302CCT7 brings to the board
It packs 256 KB of Flash and 40K x 8 of SRAM — enough for a moderate firmware stack with OTA staging or data logging buffers. The 48-LQFP package keeps the footprint compact while still offering 37 I/O and a full set of peripherals: CAN, USB, I2C, SPI, UART/USART, LIN, and IrDA.
Lifecycle — still a current production part
The base product number STM32F302 covers a range of Flash and RAM options in the same footprint, making a drop-in density upgrade possible later without a board spin.
