Infineon Memtool 4.9 →
If you enable high-security read protection, Memtool will warn that a full chip erase (via BSL) is required to reprogram—and that requires a special “BSL unlock sequence” using a specific key. Without the key, the chip becomes permanently locked. Memtool 4.9 handles this more transparently than later versions.
The memory map viewer now distinguishes between cached and non-cached address regions more clearly. It’s a small change, but when you’re verifying that your PCP (Peripheral Control Processor) code is in the right spot, it saves minutes of squinting.
| Feature | Memtool 4.9 | Memtool 5.x | DAVE 4.x | AURIX Flasher | |---------|------------|-------------|----------|----------------| | XC8xx support | ✅ Full | ❌ Removed | ⚠️ Limited (via plugin) | ❌ | | XC166 support | ✅ Yes | ✅ Basic | ⚠️ Legacy plugin only | ❌ | | XC2000 support | ✅ Full | ✅ Good | ✅ Partial | ❌ | | AURIX TC2xx | ❌ | ✅ | ✅ | ✅ | | GUI complexity | Minimal | Moderate | High | Minimal | | License cost | Free | Free (with login) | Free (DAVE) | Free | | Windows 11 ready | ⚠️ Legacy mode | ✅ | ✅ | ✅ |
Verdict: If your project uses XC800/166/2000, Memtool 4.9 is superior to anything newer because modern tools have deprecated BSL support for these families.
Infineon Memtool (Memory Tool) is a standalone Windows application designed for in-system programming (ISP) of Infineon microcontrollers. It communicates directly with the chip’s embedded bootstrap loader over a UART (serial) or CAN interface, requiring no external debugger like a J-Link or DAP (though newer versions also support those). infineon memtool 4.9
Key Functions of Memtool:
For production line programming, Memtool 4.9 supports scripting. Example:
Memtool.exe /device XC878 /com 3 /baud 115200 /erase /program firmware.hex /verify /exit
This is invaluable for integrating into automated test racks.
Embedded system longevity is measured in decades, not years. Millions of devices running XC878-based motor controllers, XC164-based automotive ECUs, and XC2000-based industrial drives are still in active service. When those devices need firmware updates or recovery from corrupted Flash, Infineon Memtool 4.9 is often the only tool that can talk to their bootstrap loader without an expensive JTAG debugger. If you enable high-security read protection, Memtool will
While Infineon pushes forward with AURIX and ARM-based controllers, the company has wisely left Memtool 4.9 in the public domain—a testament to the importance of backward compatibility. For engineers, it’s a lightweight, reliable, and eminently usable piece of software that has earned its place on every legacy embedded workbench.
Final Recommendation: Keep a copy of Memtool 4.9 on a dedicated Windows 7 virtual machine. Pair it with a quality USB-UART adapter (e.g., FT2232H). Learn its command-line switches for automation. And never, ever lose the installation file—it’s a lifeline for the industrial past that still powers our present.
