Legacy Pack for a particular microcontroller series, like the LICENSE: How to access former Keil products - Arm Developer 17 Sept 2025 —

Keil MDK-ARM version 4.7 (and the 4.7x series) is a significant legacy version of the Microcontroller Development Kit, primarily known for being one of the final stable releases before the major architecture shift to MDK version 5. It is still used today by developers maintaining older industrial or automotive systems. Key Facts About Version 4.7

IDE: This version uses the µVision4 interface. Unlike the current version 6, it relies on a built-in device database rather than the modern "Software Pack" system.

Device Support: It is designed for ARM7, ARM9, and early Cortex-M devices (like the Cortex-M3 and M4).

Legacy Value: Many developers seek this specific version because it includes native support for older processors that sometimes require "Legacy Support" packs in newer MDK versions. How the Download & Installation Works To get MDK-ARM 4.7 working properly, follow these steps:

Obtain the Installer: You can generally find older versions by entering a valid Product Serial Number (PSN) or License Code (LIC) on the Keil Product Downloads page.

Lite/Evaluation Mode: If you do not have a license, the installer typically defaults to a Lite/Evaluation edition, which limits the compiled code size (usually to 32KB) but allows full access to the IDE and debugger.

Installation Path: If you already have a newer version of Keil (like MDK v5 or v6) installed, it is best to install version 4.7 into a separate folder to avoid file conflicts.

License Management: To activate a full version, navigate to File > License Management within the µVision IDE and enter your LIC. Modern Alternatives

If you are starting a new project, Arm now offers a Community Edition of the latest MDK. This version has no code size limits for non-commercial use, making it a much more powerful (and free) alternative to the 32KB-limited evaluation version of 4.7. Keil Product Downloads
