List of common microcontrollers


This is a list of common microcontrollers listed by brand.

Altera

In 2016, Atmel was sold to Microchip Technology.
ELAN Microelectronics Corporation is an IC designer and provider of 8-bit microcontrollers and PC Peripheral ICs. Headquartered in Hsinchu Science Park, the Silicon Valley of Taiwan, ELAN's microcontroller product range includes the following:
These are clones of the 12- and 14-bit Microchip PIC line of processors, but with a 13-bit instruction word.

EPSON Semiconductor

Espressif Systems, a company with headquarters in Shanghai, China made their debut in the microcontroller scene with their range of inexpensive and feature-packed WiFi microcontrollers such as ESP8266.
Until 2004, these µCs were developed and marketed by Motorola, whose semiconductor division was spun off to establish Freescale.

Holtek

Holtek Semiconductor is a major Taiwan-based designer of 32-bit microcontrollers, 8-bit microcontrollers and peripheral products. Microcontroller products are centred around an ARM core in the case of 32-bit products and 8051 based core and Holtek's own core in the case of 8-bit products. Located in the Hsinchu Science Park, the company's product range includes the following microcontroller device series:
offers microcontrollers for the automotive, industrial and multimarket industry. , a component based auto code generation free tool, provides faster development of complex embedded projects.

produces microcontrollers with three very different architectures:
8-bit PICmicro, with a single accumulator :
16-bit microcontrollers, with 16 general-purpose registers
32-bit microcontrollers:

is a joint venture comprising the semiconductor businesses of Hitachi, Mitsubishi Electric and NEC Electronics, creating the largest manufacturer in the world.
semiconductors created a line of 6502 based microcontrollers that were used with their telecom chips. Most of their microcontrollers were packaged in a QIP package.
Manufactures a line of 8-bit 8051-compatible microcontrollers, notable for high speeds and large memories in relatively small package sizes. A free IDE is available that supports the USB-connected ToolStick line of modular prototyping boards. These microcontrollers were originally developed by Cygnal. In 2012, the company introduced ARM-based mixed-signal MCUs with very low power and USB options, supported by free Eclipse-based tools. The company acquired Energy Micro in 2013 and now offers a number of ARM-based 32-bit microcontrollers.
Microcontrollers acquired from Fujitsu:
The , in particular, provide a high level of community-based, open source support through the TI .
