Infineon Memtool 4.9: The Essential Flash Programming Solution for XC2000, XE166, and Legacy TriCore
Infineon Memtool 4.9 represents a significant, albeit legacy, version of Infineon’s dedicated in-circuit flash programming software. Designed primarily for engineers working with Infineon’s 16-bit XC2000, XE166 families, and certain legacy 32-bit TriCore-based microcontrollers (such as the TC11xx, TC17xx, and TC23xx series), Memtool 4.9 provides a lightweight, no-frills solution for flashing, erasing, and verifying device memory.
Unlike modern universal programmers or debuggers that bundle flashing as a secondary function, Memtool 4.9 is purpose-built. Its key features include:
- Direct Device Access: Communicates via standard interfaces like UART (asynchronous serial), CAN, or DAP (Device Access Port) using a suitable bridge (e.g., USB-to-UART converter or Infineon’s own DAS (Debug Access Server)).
- Hex File Handling: Seamlessly loads Intel HEX, Motorola S-record, or binary files, displaying clear memory range maps.
- Fine-Grained Memory Operations: Allows users to program, verify, read, or erase individual sectors, pages, or the entire flash—critical when protecting bootloaders or calibration data.
- Configuration Security: Stores device-specific programming settings (interface, baud rate, security passwords) in reusable project files.
Why 4.9 Matters: This version is often cited in application notes and forum discussions as the last release before Infineon pivoted to Memtool 2021 (based on a newer architecture with DAS 8.0+). Many engineers keep Memtool 4.9 on legacy Windows 7/XP machines because it is stable, lightweight (<20 MB), and does not require a full IDE license.
Limitations: Memtool 4.9 is not intended for debugging, real-time variable monitoring, or support for modern AURIX™ TC2xx/TC3xx devices. It also lacks native integration with Eclipse-based environments and may struggle with Windows 10/11 driver signatures for older parallel port or LPT dongles.
Use Case Example: A field service technician updating firmware on an industrial motor drive running an XE164FN-40F80L would connect via RS-232, launch Memtool 4.9, load the updated .hex file, click Program, and verify the checksum—all without installing a 2 GB IDE. infineon memtool 4.9
Conclusion: Infineon Memtool 4.9 is a reliable, focused tool for those maintaining older Infineon microcontroller-based products. While obsolete for new AURIX development, it remains a valuable utility in the embedded engineer’s toolkit for legacy system support and production floor programming of XC2000/XE166 devices.
Infineon MemTool 4.9 is a specialized PC software designed for erasing, programming, and verifying on-chip flash and OTP memory for several Infineon microcontroller families. Infineon Developer Center Key Features and Capabilities Broad Device Support : It handles memory devices for the Aurix/TriCore microcontroller families. Operational Modes
: Users can perform functions like erasing, programming, verifying, and protecting selectable flash sections or the entire program and data flash areas. File Format Support : The tool typically allows you to open Intel-Hex-Files to write contents into the target memory. Batch & Scripting : Version 4.9 supports batch commands via IMTMemtool.exe
, allowing for automated programming through command-line operations. Infineon Developer Center Connectivity and Hardware Requirements : It is compatible with PCs running Microsoft Windows 10 or newer Interface Options RS232/Serial Infineon Memtool 4
: Standard RS232 ports can be used to connect the host PC to the target device. Hardware Debuggers
: It supports the onboard wiggler on Infineon evaluation boards and the external miniWiggler for custom hardware designs. Troubleshooting
: Common user issues often involve establishing a connection (e.g., "Can't establish connection" errors) between the host and the Aurix/TriCore controllers. Infineon Developer Community Getting the Software

Security & Safety Notes
- Always ensure target power rails and wiring are correct to avoid damaging devices.
- Treat lock-bit operations as irreversible; require backups and approvals before automating.
Step 4: Protection and Execution
- Set security bits: “Flash” → “Configure Protection” → Set read/write protection (if needed).
- To start user code: either reset the device (toggle power) or select “Target” → “Start Execution”.
Step-by-step guide:
- Disable Driver Signature Enforcement (for legacy USB drivers on Win 10/11).
- Install DAS first. Reboot.
- Install MEMTool 4.9 as Administrator.
- Connect your debug probe (e.g., Segger J-Link or Infineon MiniWiggler).
- Launch MEMTool – select
File > New Projectand choose your exact derivative (e.g., XC886CM).
Pro tip: MEMTool 4.9 stores project settings in
.mtpfiles. Always back these up, as version incompatibility with newer MEMTools is common.
4. Why Version 4.9 Specifically? (Legacy Gold)
Newer versions (5.x, 6.x) dropped support for many XC800 derivatives or introduced cryptic license restrictions. Infineon MEMTool 4.9 is the last version that:
- Works offline fully (no license server pings).
- Supports obscure XC822/XC878 boot ROM variants (common in automotive blower controls).
- Handles P-SRAM (Program SRAM) paging correctly for XC2000 Safety Island.
- Allows direct access to User Access Block (UAB) – a 128-byte area in XC800 that holds configuration passwords. Newer tools often hide this for “safety.”
Engineers maintaining assembly-coded motor control loops from 2012 swear by MEMTool 4.9 because it never silently “optimizes” memory writes.
6. Typical Workflow
A standard operational flow using MemTool 4.9 involves the following steps:
- Selection: Launch MemTool and select the specific MCU part number from the device list.
- Connection: Choose the communication interface (e.g., DAS JTAG over MiniWiggler) and establish a connection. The tool reads the chip ID to verify the selection.
- Configuration: Set the target clock settings (crucial for flash programming timing).
- File Load: Import the Hex file (Intel Hex, Motorola S-record, or Binary) to be programmed.
- Operations:
- Erase: Clear the flash sectors.
- Program: Write the data.
- Verify: Read back and compare.
- Execution: Reset the device to run the new application.
Legacy Parts
- C161, C164, C165, C167 (Classic C166)
- C500/800 base series.
Note: Memtool 4.9 does not support modern AURIX (TC2xx, TC3xx) families. For those, you need AURIX Flasher or Memtool 5.x.
