Microcontroller Suppliers' List

This page is now obsolete and will be removed. A new version of this page with microcontroller manufacturers and suppliers is now available on embedeo.org. Please, update your bookmarks.

This page lists the most popular suppliers of embedded microcontrollers in alphabetical order. Microcontrollers with "soft" cores and microprocessors with external program and data memory are not listed here.

The table below lists the most popular vendors (suppliers, manufacturers) of microcontrollers and some specific properties of their related product portfolio. Such properties include: available databus widths, specific connectivity peripherals and partticular operating temperature range. In order to keep the table as compact as possible, there are single letters within the table designating type of the program memory or type of the CPU core (if it is a "standard" one, like 8051 microcontroller, for example) being used by each supplier. The explanation of the letters is provided below the table. Finally, the purpose of this table is to speed up the selection process of microcontrollers for new designs or upgrading existing ones by pointing out the players in a given market niche. There is no warranty that the information below is correct or up to date. If you think the information for your favourite company is missing or incorrect, do not hesitate to contact us, please. Usually, you can find a contact e-mail at the bottom of the page.

Meaning of values and abbreviations within the table.

* - A standalone asterisk in a cell means the corresponding vendor offers at least one microcontroller conforming to the category (column). When the asterisk is used in combination with other letters it means the vendor probably offers microcontrollers not covered by the meaning of particular letters.

5 - There is at least one device compatible to industry standard 8051 microcontroller core in the category marked with this digit.

A - There is at least one microcontroller based on ARM-core (most likely ARM7TDMI) in the category marked with this letter.

M - There is at least one microcontroller with Mask-ROM program memory in the category marked with this letter. So far Mask-ROM alternatives are expected to be cheap for well established designs and large volume mass production. However some manufacturers stake on all-flash concept, focusing their efforts on a reprogrammable technology only with very compettetive prices.

F - There is at least one microcontroller with reprogrammable program memory, Flash or EEPROM, in the category marked with this letter.

Name - Please, note, a shortened name or abbreviation appears in this column. You can find correct or complete name of the company on company's website following the corresponding link.

DSP - Digital Signal Processors are categorized purely by vendor's point of view. Sometimes, this is rather a marketing approach, than real technical characteristic. Some manufacturers produce 16-bit, 40MHz microcontrollers entitled DSP, while other manufacturers entitle their 32-bit, 60MHz chips, simply microcontrollers. It is better to chek out for specific features such as signal processing pipelines or circular buffers in the vendor's documentation.

105 - A letter in this column means the corresponding vendor provides microcontrollers rated for operation within -40... +100 centigrade. Usually, such temperature range is requirement for automotive electronics but it does not automatically mean automotive qualification, like AECQ100 of AEC, for example.

CAN - A letter in this column means the vendor offers microcontrollers with on-chip connectivity for Controller Area Network.

USB - It designates microcontrollers with on-chip Universal Serial Bus connectivity, either function or host type.

Eth. - It designates microcontrollers with on-chip Ethernet connectivity, ragrdless its speed grade.
