Connectivity includes Ethernet MAC, CAN 2.0B, two USB OTG interfaces (one with HS), six UART/USART, three SPI, three I²C, and an 8-bit camera interface (DCMI). The 114 general-purpose I/O pins provide ample headroom for HMI panels, sensor arrays, and actuator control. ## Package and footprint considerations for the 144-LQFP The part ships in a 144-pin LQFP with a 20×20 mm body and 0.5 mm pitch. This is a hand-solderable QFP for prototyping, but the fine pitch demands a controlled reflow profile and careful inspection. For new designs, there is no near-term LTB risk, and the STM32F4 series has a long roadmap history, making this a safe choice for production programs. ## Second-source and cross-ship alternatives The STM32F407ZET6 is a specific density and package variant within the STM32F405/407/415/417 family. A direct pin-compatible alternative is the STM32F407VGT6, which shares the same 144-LQFP footprint and peripheral set but offers 1 MB Flash and 192 KB SRAM — a drop-in upgrade for firmware that outgrows the 512 KB budget. The STM32F407ZET6 has no official second-source from another manufacturer; dual-sourcing relies on stocking multiple date-code lots from authorized distribution. The STM32L151CBU6A is a different architecture (Cortex-M3, lower power, 32 MHz) and is not a functional replacement.","metaTitle":"STM32F407ZET6 STM32F4 ARM Cortex-M4 MCU, 168MHz, 512KB Flash","metaDescription":"STM32F407ZET6 32-bit ARM Cortex-M4 MCU at 168MHz with 512KB Flash, 192KB SRAM, Ethernet, CAN, USB OTG, 114 I/O.
