The STM32F413VHT6 is a 32-bit ARM Cortex-M4 MCU from STMicroelectronics' STM32F4 series, clocked at 100 MHz. That 1.5 MB Flash means you can field-update firmware over CAN or USB OTG and still have room for a fallback bootloader.
Connectivity and I/O — one chip covers the interface bill
81 GPIOs in a 100-LQFP package give you headroom for a parallel LCD, external memory bus (EBI/EMI), and a handful of sensors or actuators. The peripheral set includes CANbus, USB OTG, multiple SPI and I²C, QSPI for fast serial NOR Flash, SAI for digital audio, and SDIO for an SD card slot. That covers most industrial and IoT interface requirements without external bridge chips. Two 12-bit DACs and sixteen 12-bit ADC channels handle analog I/O on the same die — no separate ADC part needed for a typical sensor-input or audio-output design.
