Infineon Memtool 4.9

MEMTool (Memory Tool) is a lightweight, Windows-based application designed specifically for low-level memory manipulation and debugging of Infineon microcontrollers. Version 4.9 is the culmination of a generation focused on:

Unlike DAVE or Tasking, MEMTool is not a compiler or an IDE. It is a debug and test tool. You write your code in Keil, SDCC, or Tasking, generate an ELF/HEX file, and then use MEMTool 4.9 to: infineon memtool 4.9

Key distinction: MEMTool 4.9 uses DAS (Debug Access Server) as its driver layer, making it compatible with a wide range of debuggers, including the famous Keil Ulink, Segger J-Link, and Infineon’s own OCDS (On-Chip Debug Support) level 1. Unlike DAVE or Tasking, MEMTool is not a compiler or an IDE

Pro tip: MEMTool 4.9 stores project settings in .mtp files. Always back these up, as version incompatibility with newer MEMTools is common. Key distinction : MEMTool 4

Since Infineon has officially removed Memtool 4.9 from its main download portal (redirecting to Memtool 5.x), you’ll need to source it from legacy support archives or authorized distributors. Be cautious of third-party sites—verify checksums.

Since Infineon discontinued direct links, try these legal sources:
