is a specialized, free-of-charge software utility designed for the on-chip programming of non-volatile memory devices—specifically Flash and One-Time Programmable (OTP) memory—across a broad range of Infineon microcontrollers.
: Reworked UCB_SWAP configuration and added support for SOTA (Software Over The Air) mode with unlocked swap blocks. infineon memtool 49
Programming with Memtool 4.9 typically follows a structured sequence within its graphical user interface: Target Configuration: : These may occur if sector protection is active
: Enables programming via serial (ASC/UART) interfaces. The interface looks sparse by modern standards, but
: These may occur if sector protection is active. Use MemTool to reset protection before attempting to re-program.
Launch MEMTool. The interface looks sparse by modern standards, but it is highly functional.
Memtool is Infineon’s proprietary, low-level memory programming and debugging tool for their , AURIX™ , and legacy C166/XC166 microcontroller families. Version 4.9 represents a mature, stable release before the transition to newer tools like AURIX™ Memtool or integration into Infineon Development Studio (IDS) .
