The price of microcontrollers can vary widely depending on their features, performance, and brand. Generally speaking, the cheapest microcontrollers on the market cost just a few cents per unit, while more advanced microcontrollers with high processing power and advanced features can cost several dollars or more.

For example, some of the cheapest microcontrollers available include the Atmel AVR ATTiny10, which costs around $0.20 per unit, and the Microchip PIC10F200, which costs around $0.25 per unit.

On the other end of the spectrum, some of the most advanced microcontrollers can cost hundreds of dollars or more, depending on their performance and features. These microcontrollers are typically used in high-performance applications such as automotive, aerospace, and multimedia.

However, it’s important to note that the price of a microcontroller is just one factor to consider when choosing a microcontroller for your project. Other factors such as processing power, memory capacity, I/O interfaces, and software development tools should also be taken into account when selecting a microcontroller that best meets your project requirements.

Midle price:

The price range for mid-performance microcontrollers varies depending on the brand and specific model of the microcontroller. Generally, mid-performance microcontrollers have more features and capabilities than the cheapest microcontrollers, but they are also more expensive.

Some mid-performance microcontrollers can cost around $1 to $2 per unit. For example, the Microchip PIC18F45K22 microcontroller costs around $1.50 per unit and has 32 KB of program memory, 2 KB of RAM, and a 12-bit ADC. Similarly, the STMicroelectronics STM32F103C8T6 microcontroller costs around $2 per unit and has 64 KB of program memory, 20 KB of RAM, and multiple communication interfaces such as SPI, I2C, and USART.

However, some mid-performance microcontrollers with more advanced features can cost more, such as the Atmel SAM3X8E ARM Cortex-M3 microcontroller, which costs around $8 per unit and has 512 KB of flash memory, 96 KB of RAM, and multiple communication interfaces.

It’s important to keep in mind that the price of a microcontroller is just one factor to consider when selecting a microcontroller for your project. You should also consider the processing power, memory capacity, I/O interfaces, and software development tools when choosing a microcontroller that best meets your project requirements.

High price:

The price range for high-performance microcontrollers varies widely depending on the brand, specific model, and features of the microcontroller. Generally, high-performance microcontrollers have advanced features, faster processing speeds, and larger memory capacity, which makes them more expensive than mid-performance or low-performance microcontrollers.

Some high-performance microcontrollers can cost around $5 to $10 per unit. For example, the STMicroelectronics STM32H743ZI microcontroller costs around $8 per unit and has 2 MB of flash memory, 1 MB of RAM, and a 480 MHz ARM Cortex-M7 processor. Similarly, the Texas Instruments TMS320F28379D microcontroller costs around $10 per unit and has 1.5 MB of flash memory, 320 KB of RAM, and a 200 MHz C28x CPU.
