The STM32F407VGT6 is a high-performance 32-bit microcontroller from STMicroelectronics based on the ARM Cortex-M4 core with a Floating Point Unit (FPU). It belongs to the STM32F4 series and is designed for applications requiring digital signal control and high processing power .
The device features a 168 MHz ARM Cortex-M4 CPU with FPU and DSP instructions, delivering up to 210 DMIPS processing power . The ART Accelerator™ enables zero-wait state execution from Flash memory at full 168 MHz frequency .
The LQFP-100 package provides 82 I/O pins, most of which are 5V-tolerant, facilitating direct interfacing with 5V logic systems without external level shifters .
Key built-in features include:
-
Memory: 1 MB Flash with read-while-write support, 192 KB SRAM (including 64 KB Core Coupled Memory for time-critical operations), 4 KB backup SRAM
-
Flexible Memory Controller (FSMC): Supports SRAM, PSRAM, NOR, NAND Flash, and LCD parallel interface (8080/6800 modes)
-
Analog peripherals: Three 12-bit ADCs (up to 2.4 MSPS, 7.2 MSPS in triple interleaved mode) and two 12-bit DACs
-
DMA: 16-stream DMA controller with FIFO support for efficient data transfer
-
Serial Audio Interface (I2S): For high-quality audio applications
-
RTC: Calendar RTC with sub-second accuracy and backup registers
The device supports multiple low-power modes including Sleep, Stop, and Standby, optimizing power consumption for battery-powered applications . Internal RC oscillators (16 MHz with 1% accuracy reduced to 0.25% after factory calibration, and 32 kHz) provide flexible clock options .
The STM32F407VGT6 is fully supported by ST’s ecosystem including STM32CubeMX, STM32CubeIDE, HAL libraries, and major third-party toolchains (Keil MDK, IAR Embedded Workbench) .
