About Keil

The Keil products from ARM are the world leading development tools for Cortex-M, Cortex-R, ARM7, ARM9, C166, 251, and 8051 microcontroller families. The Keil products include C/C++ compilers, debuggers, integrated environments, RTOS, simulation models, and evaluation boards.


“As a startup we need to move fast implementing our technology in new products and with different partners. We are glad to be using Keil as a solid basis of our embedded software architecture, it allows us to select a wide range of MCUs addressing our various needs but keeping time to market short.”

Inouk Bourgon, Chief Technical Officer, Airboxlab S.A.


MDK Version 5 Overview

The MDK Core contains all development tools including IDE, Compiler, and Debugger. The new Pack Installer adds and updates Software Packs for devices, CMSIS, and middleware.

Software Packs that add support for a complete microcontroller family are called Device Family Packs.

Today only some devices are supported by Device Software Packs, but we will add support for more microcontroller devices shortly.

Software Packs, Peripheral Drivers, and Run-Time Environment

Software components of installed Software Packs are selected in the Run-Time Environment Window and standardized drivers to device peripherals provide the interface to the middleware, that is part of the MDK Professional Edition.

Product Life Cycle Management with Software Packs

Software development is getting more important in today's product development. This also increases the impact of software development on the product lifecycle management (PLM).
