There are various company which offers the 32-bit microcontrollers.
ST, Texas Instrument, Microchip, NXP and Espressif Systems are just to name a few. These all offer a good balance of cost and performance.
Each company offers its development board which host a basic environment to support the microcontroller. Depending upon one’s need one may choose the board.
The 32-bit offering is very wide and you will find it overwhelming to select the microcontroller at first. It is best to finalize your current needs first and then select the microcontroller. Because it is easy to get confused as there are so many.
There are slight differences between these microcontrollers. If you compare the recent microcontroller, you will find that they all offer almost the same processing core, the difference comes in the included peripherals.
Most companies offer their offering in
– Low Power – These are great if you have a battery-driven embedded system. Some of the microcontrollers also host a clock generation circuitry inside the package. Which reduces the cost of the system.
– General Purpose – These microcontrollers offer a balance between low power operation and performance. If you do not have a battery constraint they are good.
– High Performance – These are great if you have really computation hungry system which does on package processing of data. They also have other peripheral’s which can support visual display such as HDMI and Radio control etc. They are the most expensive. Most in general are not suitable for beginers.
