MDK Microcontroller Development Kit

Keil MDK is the most comprehensive software development solution for Arm-based microcontrollers and includes all components that you need to create, build, and debug embedded applications.

Software Packs add device support and software components that you can use as building blocks for your application.

Product Components

MDK-Core is based on µVision with leading support for Cortex-M devices including the new Armv8-M architecture.

DS-MDK contains the Eclipse-based DS-5 IDE/Debugger and supports 32-bit Cortex-A processors or hybrid systems with 32-bit Cortex-A and Cortex-M.

MDK includes two Arm C/C++ Compilers with assembler, linker, and highly optimize run-time libraries that are tailored for optimum code size and performance.

Software Packs may be added any time to MDK-Core or DS-MDK making new device support and middleware updates independent from the toolchain. They contain device support, CMSIS libraries, middleware, board support, code templates, and example projects.

New is the IPv4/IPv6 networking communication stack that is extended with Arm mbed™ software components to enable Internet of Things (IoT) applications.


Product evaluation, small projects, and education. Code size restricted to 32 Kbyte.
