ARM® Keil® MDK Version 5.20 is the industry-leading standard software development solution for ARM Cortex® microcontrollers. For Cortex-M devices, the new MDK-Plus edition adds comprehensive middleware for applications that require File System, Graphics, TCP/IP Networking, or USB Device interfaces.

Keil MDK 5.20 Overview
available only in MDK-Professional edition. DS-MDK is available in July 2016.
The MDK Middleware is designed, tested, and optimized for ARM Cortex-M based platforms. StandardizedCMSIS-Driver interfaces provide the software layer to the device peripherals. Today, the following device families are supported out-of-the-box with CMSIS-Driver interfaces:

  • Atmel SAME70
  • Atmel SAMS70
  • Atmel SAMV7x
  • Infineon XMC1000
  • Infineon XMC4000
  • NXP Kinetis K64
  • NXP LPC1700
  • NXP LPC1800
  • NXP LPC4000/LPC4300
  • NXP LPC54000
  • Silicon Labs EFM32 Giant Gecko
  • STMicroelectronics STM32F1xx
  • STMicroelectronics STM32F2xx
  • STMicroelectronics STM32F4xx
  • STMicroelectronics STM32F7xx

The CMSIS-Driver Validation software pack allows you to verify the implementation and configuration of the interfaces with your target hardware. It detects potential errors that may affect the operation of the middleware.
