Keil is a German software subsidiary of Arm Holdings. It was founded in 1982 by Günter and Reinhard Keil, initially as a German GbR. In April 1985 the company was converted to Keil Elektronik GmbH to market add-on products for the development tools provided by many of the silicon vendors. Keil implemented the first C compiler designed from the ground-up specifically for the 8051 microcontroller.

Keil provides a broad range of development tools like ANSI C compiler, macro assemblers, debuggers and simulators, linkers, IDE, library managers, real-time operating systems (currently RTX5)cite-ref-1[1]cite-ref-2[2]cite-ref-3[3] and evaluation boards for over 8,500 devices.cite-ref-4[4]cite-ref-5[5]

In October 2005, Keil (Keil Elektronik GmbH in Munich, Germany, and Keil Software, Inc. in Plano, Texas) were acquired by Arm.cite-ref-6[6]cite-ref-7[7]cite-ref-8[8]

Since the merger with Arm, the company is still active in providing products and services.cite-ref-9[9]cite-ref-10[10]cite-ref-11[11]cite-ref-12[12]
