About Keil

Keil was founded in 1985 to market add-on products for the development tools provided by many of the silicon vendors. It soon became evident that there was a void in the marketplace that must be filled by quality software development tools. It was then that Keil implemented the first C compiler designed from the ground-up specifically for the 8051 microcontroller.

In October 2005, Keil (Keil Elektronik GmbH in Munich, Germany, and Keil Software, Inc. in Plano, Texas) was acquired by ARM. Read more about the Keil acquisition.

Since the acquisition, ARM has continued the development and support of Keil products for existing 8051, 251, and C166 markets. In addition, we have driven innovation to support and significantly improve software development around ARM processor-based devices.

Today, the Keil development tools are used by a wide range of developers building software applications for end products targeting diverse vertical markets such as Aerospace, Banking, Healthcare, Automotive, Transportation, Manufacturing, Consumer, Military and Telecommunications.
