Introduction
Microcontroller boards are used in a variety of applications such as drones, robots, IoT, and more. Among the various microcontroller boards available in the market, the STM32F4 and STM32F7 are two high-performance microcontroller boards. In this post, we will compare the features and specifications of these two microcontroller boards.
STM32F4
STM32F4 is a high-performance microcontroller board that is built around the ARM Cortex-M4 core. The core can operate at a clock speed of up to 180 MHz. The board has 2 MB of flash memory and 512 KB of RAM. It also has a floating-point unit (FPU) that can perform complex arithmetic operations.
One of the key features of the STM32F4 is its DSP capabilities. The board has a dedicated DSP core that can perform fast Fourier transforms (FFT), digital filters, and more. This feature makes the STM32F4 an ideal choice for applications that require real-time signal processing.
The STM32F4 also has a rich set of peripherals such as USB, CAN, I2C, SPI, and Ethernet. These peripherals make it easy to interface with external devices and connect to the internet.
STM32F7
STM32F7 is an advanced microcontroller board that is built around the ARM Cortex-M7 core. The core can operate at a clock speed of up to 216 MHz. The board has 1 MB of flash memory and 320 KB of RAM. It also has a floating-point unit (FPU) that can perform complex arithmetic operations.
One of the key features of the STM32F7 is its high-resolution TFT display controller. The board can display up to 800x600 resolution in 24-bit color depth. This feature makes the STM32F7 an ideal choice for applications that require high-quality displays.
The STM32F7 also has an advanced audio processing unit (APU). The APU can perform audio decoding and encoding in various formats such as MP3, AAC, and more. This feature makes the STM32F7 an ideal choice for applications that require high-quality audio.
Comparison
Here is a comparison of the key features and specifications of the STM32F4 and STM32F7 microcontroller boards.

|---|---|---|
| Clock Speed | Up to 180 MHz | Up to 216 MHz |
| Flash Memory | 2 MB | 1 MB |
| RAM | 512 KB | 320 KB |
| Floating-Point Unit (FPU) | Yes | Yes |
| DSP Core | Yes | No |
| Display Resolution | N/A | Up to 800x600 |
| Audio Processing Unit (APU) | No | Yes |
| USB | Yes | Yes |
| CAN | Yes | Yes |
| I2C | Yes | Yes |
| SPI | Yes | Yes |
| Ethernet | Yes | Yes |
As you can see from the comparison table, the STM32F7 is an advanced version of the STM32F4 with some additional features such as a high-resolution display controller and an audio processing unit. However, the STM32F4 has a DSP core that is not present in the STM32F7.
Conclusion
Both the STM32F4 and STM32F7 are high-performance microcontroller boards with their own set of features and specifications. The choice between these two boards ultimately depends on the specific requirements of your application.
