The 82 I/O pins and the peripheral set — Ethernet MAC, two CAN 2.0B interfaces, USB OTG HS/FS, twelve 16-bit timers, two 32-bit timers, three 12-bit ADCs (16 channels), and two 12-bit DACs — make it a single-chip gateway for industrial automation, motor drives, and networked embedded systems that need deterministic response and rich connectivity.
1 MB Flash and 192 KB SRAM — sizing the firmware and data buffers
The 1 MB Flash (1M x 8) is organized for firmware that includes a full RTOS, a TCP/IP stack, a file system, and application code without external memory. The 192 KB SRAM (192K x 8) supports multi-packet Ethernet buffers, CAN message queues, and real-time data acquisition. The Flash is rated for 10,000 erase/write cycles typical — adequate for field-update scenarios with wear-leveling in the bootloader.
100-LQFP (14x14 mm) — board-level integration check
Connectivity set — Ethernet, CAN, USB OTG, and serial interfaces
The STM32F407VGT6 integrates an Ethernet MAC (MII/RMII), two CAN 2.0B controllers, a USB OTG HS port (with ULPI for external PHY), a USB OTG FS port, three SPI, three I²C, four USARTs plus two UARTs, an IrDA transceiver, and a DCMI camera interface. This peripheral mix eliminates the need for separate interface ICs in many gateway, HMI, and data-logger designs. The DMA controller (16-stream, 8-channel) offloads peripheral-to-memory transfers without CPU intervention.
