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.
|MDK-Core is based on µVision (Windows only) with leading support for Cortex-M devices including the new Armv8-M architecture.
DS-MDK contains the Eclipse-based (Windows and Linux) DS-5 IDE/Debugger and supports 32-bit Arm Cortex-A processors or heterogeneous systems (32-bit Arm Cortex-A and Arm 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.
The IPv4/IPv6 networking communication stack is extended with Arm mbed™ software components to enable Internet of Things (IoT) applications.

A node-locked license allows using MDK by exactly one person on a maximum of two computers (single-user). No network connection required.
A Floating-User License allows developers to use MDK on multiple computers. Floating-User Licenses require a file server hosting a license file. A network connection to check out the floating-user license is required.
A FlexLM License allows developers to use MDK on multiple computers. A network connection to check out a FlexLM license is required.
MDK for STMicroelectronics STM32F0 and STM32L0:
The MDK for STMicroelectonics STM32F0 and STM32L0 is a license paid by STMicroelectronics. It is free-to-use for software developers working with STM32 devices based on the ARM Cortex-M0 and ARM Cortex-M0+ cores.
All MDK editions are designed for 32-bit and 64-bit variants of Microsoft Windows and have the same system requirements. DS-MDK also runs on Linux hosts.
