STM32F1 vs. STM32F4: Which Microcontroller is Best for Data Logging?

When it comes to data logging, choosing the right microcontroller can make all the difference in the world. In this post, we will compare the STM32F1 and STM32F4 microcontrollers to determine which is the best choice for data logging.

Processing Power

The STM32F4 is designed with a higher processing power than the STM32F1. It has a 32-bit CPU that runs at a higher clock speed, which means it can process more data at a faster rate. This can be especially important when logging data from multiple sensors simultaneously.

Power Consumption

Both microcontrollers have low power consumption, making them ideal for battery-powered data logging applications. However, the STM32F1 has a lower power consumption compared to the STM32F4. This makes it a better choice if you need to maximize battery life.

Memory

The STM32F4 has more memory than the STM32F1. It has more Flash memory and a larger RAM size. This allows for a larger number of data points to be stored and processed simultaneously.

Peripherals

Both microcontrollers have a similar set of peripherals, including USB, CAN, and SPI interfaces. However, the STM32F4 has additional peripherals such as a SDIO interface, which allows for SD cards to be used for additional data storage.

Price

The STM32F1 is less expensive than the STM32F4, making it a more economical choice. However, the higher processing power and additional peripherals of the STM32F4 may justify the extra cost.

Conclusion

When it comes to data logging, both the STM32F1 and STM32F4 are excellent choices. The STM32F4 has a higher processing power, more memory, and additional peripherals, while the STM32F1 has lower power consumption and is more cost-effective. Ultimately the best choice will depend on the specific requirements of the project.
