Core parametrics and BOM-fit note
The STM32F412CEU6: On-chip memory is 512 KB flash and 256 KB SRAM, enough to run a real-time OS with a TCP/IP stack and store application code for a field-device gateway without external memory.
Peripheral set and connectivity
36 I/O lines bring out CAN, USB OTG, QSPI, SDIO, and multiple UART/SPI/I²C interfaces — a single MCU can manage a CANopen fieldbus, log data to an SD card, and communicate over USB to a host. Built-in peripherals include a 10-channel 12-bit ADC, DMA controller, PWM timers, and a brown-out detector — no external supervisor IC is needed for basic power-fail handling.
Lifecycle and supply posture
The part is ROHS3 compliant.
