Programming STM32 ARM Cortex-M 32-bit Microcontrollers

The STM32 series are some of the most popular microcontrollers used in a wide variety of products. They also have an excellent support base from multiple microcontroller development forums.

This family of microcontrollers from STMicroelectronics is based on the ARM Cortex-M 32-bit processor core. If you are interested in getting the best microcontroller then it would be highly recommended to try microcontrollers from STMicroelectronics distributors via

STM32 microcontrollers offer a large number of serial and parallel communication peripherals which can be interfaced with all kinds of electronic components including sensors, displays, cameras, motors, etc. All STM32 variants come with internal Flash memory and RAM.

The range of performance available with the STM32 is quite expansive. Some of the most basic variants include the STM32F0 and STM32F1 sub-series that start with a clock frequency of only 24 MHz and are available in packages with as few as 16 pins.

At the other performance extreme, the STM32H7 operates at up to 400 MHz and is available in packages with as many as 240 pins.

The more advanced models are available with Floating Point Units (FPU) for applications with serious numerical processing requirements. These more advanced models blur the line between a microcontroller and a microprocessor.

Finally, the STM32L sub-series is designed specifically for low-power portable applications running from a small battery.
