Top 8-bit Microcontrollers (MCU) Manufacturers in the World

8-bit microcontrollers have been playing a major role in modernizing electronics since early 80s. It generally refers to the width of the bit. 8-bit microcontrollers have an 8-bit CPU, which means that internal operations are done on 8-bit numbers, stored variables are in 8-bit blocks, and external I/O (inputs/outputs) is accessed via 8-bit busses. The structure of 8-bit microcontrollers is quite simple and easy to understand. Here, we have mentioned the top 8-bit microcontrollers – MCU manufacturers in the world.

Microchip Technology

Microchip MCUAlthough, Microchip Technology has a wide range of products but its 8-bit microcontrollers have made its name in the top 8-bit microcontrollers – MCU manufacturers in the world.

The ATtiny1627 MCU family of AVR microcontrollers (MCUs) are equipped with high-speed integrated analog, hardware-based Core Independent Peripherals (CIPs) and low-power performance for efficient real-time control and sensor node applications.

Silicon Labs

SILICON MCUSilicon Labs rapidly evaluate and prototype a wide variety of industrial and consumer devices using our low-power, fast-speed microcontrollers, development kits, specialized example code (like energy monitoring, USB, LCD, and touch sensors), and advanced debugging capabilities. The company’s 08-bit MCUs enable high-functioning, low-power systems by leveraging an EFM32™ ARM® Cortex®. While its EFM8™ 8051-based MCUs deliver the industry’s fastest speeds and lowest power. The company has earned its name in the top 8-bit microcontrollers – MCU manufacturers in the world.

NXP Semiconductor

NXP MCUNXP Semiconductos’s 8-bit S08 MCU portfolio includes more than 30 product families, providing a wide range of features and price options for product differentiation, to cover all kinds of automotive, industrial and consumer applications.

The company has earned its name among the top 8-bit microcontrollers – MCU manufacturers in the world.

Infineon Technologies

InfineonA microcontroller unit (MCU) contains a CPU, memory, and input/output peripherals on a single integrated circuit (IC) chip and works as a standalone small computer. This allows for a reduction in power consumption, more compact designs, and cost savings. Additionally, microcontrollers can provide functional safety and security for embedded systems. Increasingly, it is becoming critical that microcontrollers are equipped with advanced security features to avoid security compromises and prevent malware attacks. Infineon’s 8-bit MCU has made its name in the top 8-bit microcontrollers – MCU manufacturers in the world.


st mcuSTMicroelectronics’ 8-bit microcontroller platform is implemented around a high-performance 8-bit core and a state-of-the-art set of peripherals.

This platform is manufactured using an ST-proprietary 130 nm embedded non-volatile memory technology. The STM8 allows fast and safe development through enhanced stack pointer operations, advanced addressing modes and new instructions.
