STM32 series main control chip of stm32

At present, STM32 series of STM32 is the main control chip of UAV with high adoption rate in China. In this regard, STM32 is very smart. It has sponsored the National Undergraduate Electronic Design Competition for a long time. The main control chip of UAV project recommended by the competition is STM32. Students are familiar with its main control platform, and they will naturally choose it when they want to do UAV after work.

STM32 series has STM32 F0 / F1 / F2 / F3 / F4 / F7 / l0 / L1 / L4 product series, among which STM32 F4 series is widely used in UAV.

Stm32f4 Series MCU based on arm cortex-m4 adopts NVM process of STM semiconductor and art accelerator, and its processing performance reaches 225 DMIPS / 608 coremark when it is executed by flash memory at the working frequency of 180 MHz, which is the high benchmark test score of all microcontroller products based on Cortex-M core so far.

Due to the dynamic power adjustment function, the current consumption range of flash memory is 89 μ A / MHz of stm32f410 to 260 μ A / MHz of stm32f439.

Stm32f4 series includes eight compatible digital signal controller (DSC) product lines. It is a perfect combination of MCU real-time control function and DSP signal processing function
