Complete Knowledge about STM Microcontroller and its Importance

STM MCU:A MCU is a small, low cost and self-contained computer on a chip which is used as an embedded system. Several STM MCU may utilize four-bit expressions and work at a clock rate frequencies which including a little measure of RAM, timers and signal generators, parallel and serial I/O, etc.

Applications of STM MCU

It has many applications of electronic equipment such as

  • Mobile phones
  • Automobiles
  • Cameras
  • Washing machines
  • Security Alarms


It is a family of 32-bit microcontroller integrated circuits by STMicroelectronics. STM32 chips are grouped into related series which is based on 32 bit ARM Microcontroller core such as Cortex M7F, Cortex M4F, Cortex M3, and Cortex M0. Each consists of the processor core, RAM, flash memory, debugging interface and several peripherals.

STM MCU and Its Importance

As a matter of fact, STM32 is a family of microcontroller Ics which is based on the 32-bit RISC ARM Cortex M7F, Cortex M4F, Cortex M3, Cortex M0+, and Cortex M0 cores. Since STMicroelectronics licenses the ARM Processor IP from ARM Holdings. ARM core designs have several configurable options, and ST chooses the individual configuration to use for each design. It attaches their peripherals to the core before converting the design into silicon. The following tables summarize the STM Microcontroller families. STM32 Series such as L5, F7, H7, F4, F3, L4, J, etc.

They also have an excellent support base from multiple microcontroller development forums. In fact, STM32 microcontrollers offer a large number of serial and parallel communication peripherals that may interface with all kinds of electronic components such as sensors, displays, cameras, and motors, etc. All STM32 variants which are come with internal flash memory and Random Access Memory.

The range of performance available with the STM is quite expansive. The most common basic variants including the STM32F0 and STM32F1 sub-series which start with a clock frequency of only 24 Mhz and is available in packages with as few as 16 pins.

As a matter of fact, Advanced models are available with Floating Point Units(FPU) for applications with serious numerical processing requirements. Moreover, it is explicitly designed for low power portable applications running from a small battery.

Development Tools

It is required to develop the code, program and finally debug the code. The development tools including such as

  • Compiler
  • Debugger and
  • In-Circuit Serial Programmer

There are several software development tools which are available for code development on STM32. The software tools are available as IDE that combines all of the necessary tools into an integrated environment.
