MCU (microcontroller)-this year's price increase king!

Whether it is a DIY or a professional product, the core of any embedded electronic device is a microcontroller. The microcontroller helps developers to get input from the sensor by running the code/firmware and output to the actuator to control the device.

Although microcontrollers are usually developed as general-purpose components, different microcontrollers have different characteristics and functions, making them suitable for different application scenarios. Therefore, in order to meet the current diversified application requirements, the characteristics and functions of microcontrollers are constantly increasing, but the functions become more powerful, and at the same time it brings selection problems to electronic engineers.

According to the frequency of microcontrollers in product applications and the size of its technical community, electronics-lab has selected the 10 most popular microcontrollers in 2021.

1. STM32F103C8T6

STM32F10C8T6 is a popular model of the STM32F103x medium-density performance line series microcontrollers. It uses a high-performance ARM®Cortex®-M3 32-bit RISC core, operating at 72 MHz, and has a wide range of enhanced I/O and connection to two APB bus peripheral equipment.

2. ATmega328

ATmega328 can be said to be one of the most popular microcontrollers in the world, and it has always been the microcontroller of choice for many designers. Designers hope to avoid the bulky Arduino board while retaining the ease of programming, community support, and other amazing features related to the Arduino development platform.

3. PIC16F877A

PIC16F877A can be said to be the most popular 8-bit microcontroller in the PIC series of MCUs. Although some people think it is obsolete, the PIC16F877A is undoubtedly still one of the most popular microcontrollers in the world. PIC16F877A is considered to be the microcontroller that beginners who use PIC for embedded development will choose in practice, but when they become experts, it is still their preferred microcontroller.

In fact, development boards are one of the reasons why PIC microcontrollers are becoming increasingly unpopular. Although PIC development boards are usually very suitable for beginners because they come with different components that are helpful for learning, for most designers, this is unnecessary and bulky.

4. Attiny85

ATtiny series microcontrollers are popular because of their small form factor and are considered to be the preferred microcontrollers for projects that require a small form factor, and the number of GPIOs is very low. Among all the microcontrollers in this series, ATtiny85 is considered the most popular, probably because it seems to have more I/O pins compared to other products. Although Microchip has announced a series of new ATtiny chips and has carried out significant performance upgrades to them, ATtiny85 is still highly regarded, mainly because most designers have become very familiar with it over time.
The outstanding feature of ATtiny85 is its small size and relatively low power consumption characteristics.
