The STM32F407ZET7 is an STM32F4-series 32-bit MCU built around an ARM Cortex-M4 core with FPU, clocked at 168 MHz. It packs 512 KB of Flash and 192 KB of SRAM, plus a full set of peripherals including Ethernet MAC, dual CAN 2.0B interfaces, a DCMI camera interface, and an external memory controller (EBI/EMI). The 144-LQFP package gives access to 114 general-purpose I/O lines.
512 KB Flash at 168 MHz — memory headroom and execution speed
The 192 KB SRAM supports multi-packet buffering and real-time data processing without external memory in many designs. The Cortex-M4 DSP extensions and single-precision FPU offload math-intensive tasks like motor control FOC or audio filtering from the core.
Connectivity suite: Ethernet, CAN, USB OTG, and more
This part includes an Ethernet MAC (MII/RMII), two CAN 2.0B interfaces, USB OTG FS/HS, multiple SPI/I²C/UART ports, and an I²S audio interface. The Ethernet + CAN combo is a strong fit for industrial gateways, PLCs, and building automation controllers that need both fieldbus and IP connectivity. The DCMI interface allows direct connection to camera sensors for vision-based applications.
For dual-sourcing resilience, the STM32F407 family includes multiple density and package variants sharing the same Cortex-M4 core and peripheral set, though no pin-compatible second source from another manufacturer is listed.
