: If you have a valid Product Serial Number (PSN) or License Code (LIC), you can enter it on the Keil maintenance page to access all previously available versions, including 5.25.
This iteration of the IDE introduced optimized window management, multi-monitor support, and a highly intuitive user interface designed to streamline complex embedded workflows.
Starting with MDK Version 5, hardware support is delivered via "Software Packs." MDK 5.25 introduced a change where legacy device support (for older microcontrollers not supported in the new packs) was moved to a separate installer.
The Keil MDK-ARM (Microcontroller Development Kit) is the industry-standard software development environment for ARM Cortex-M based microcontrollers. Version 5.25 was a significant release, enhancing middleware, CMSIS components, and support for advanced debugging. mdkarm version 525 download link
