Infineon Memtool 49 New May 2026

The headline feature is native, hardware-accelerated support for AURIX TC4x devices. The TC4x series features up to 6 TriCore cores, a PPU (Parallel Processing Unit), and massive flash banks (up to 32 MB).

The software is available free of charge but requires registration on the Infineon website.

Crucially, Memtool remains freeware. You do not need a paid license, unlike many commercial flash tools.

Security Warning: Do not download Memtool from third-party forums. Version 4.9 includes signed drivers; fake versions circulating on file-hosting sites contain malware targeting embedded supply chains. infineon memtool 49 new

With cyber-security becoming mandatory (ISO 21434), Memtool 49 New includes a dedicated "Security Tab." This allows engineers to:

The most controversial change in previous versions was the lack of flexibility for new device families. V4.9 introduces a Plug-in System.

Engineers can now download a single .mtp (Memtool Plugin) file for a specific derivative (e.g., the new XMC7200). You no longer need to uninstall and reinstall the entire tool for a minor device variant. This is a massive quality-of-life improvement for teams managing multiple product lines.
