This part is marked EOL hot — end-of-life phase is active. ST has issued or will soon issue a last-time-buy notice.
The MCU includes CANbus, EBI/EMI for external memory or parallel LCD, I²C, SPI, UART/USART, USB OTG, and QSPI — enough to interface with most industrial sensors, displays, and communication modules.
The core runs at 100 MHz, which is the ARM Cortex-M4 clock frequency.
