Active production part — what the 100 MHz Cortex-M4 and 512 KB Flash mean for your BOM
The STM32F412ZEJ6 is a current-production 32-bit ARM Cortex-M4 MCU from STMicroelectronics' STM32F4 series, running at 100 MHz with a single-precision FPU.
Peripheral fit — CAN, USB OTG, and serial interfaces
For system architects, the connectivity block includes CANbus (2.0B active), USB OTG (host/device capable), QSPI for high-speed external Flash or RAM expansion, and a full set of legacy serial interfaces (SPI, I²C, UART, IrDA, LIN). The EBI/EMI interface can drive external parallel memories or FPGAs. The 16-channel 12-bit ADC provides analog sensing without an external converter, though the 12-bit resolution is typical for this class — expect around 10.5 ENOB at 1 MSps with proper anti-alias filtering. Brown-out reset and programmable watchdog are included for safety-critical firmware.
The base product number STM32F412 covers a family of density and package variants, but this specific -ZEJ6 suffix (512 KB Flash, 144-UFBGA) is the high-I/O, mid-density option in the series.
