If you were searching for MemTool 4.9 or the latest update, the current official release represents a significant leap forward in stability and usability for Infineon MCU development. It bridges the gap between development and production, offering a reliable way to manage Flash memory, User Configuration Blocks, and RAM data.


Infineon MemTool 4.9 is a free, Windows-based software utility specifically designed for on-chip flash programming of Infineon microcontrollers. It serves as a vital tool for developers to erase, program, verify, and protect memory sections during the development and testing phases. Key Features of MemTool 4.9

The 4.9.x series introduced significant technical improvements, transitioning the software into a modern development environment:

64-bit Architecture: Starting with version 4.9 (released in 2021), MemTool became a full 64-bit application, removing support for 32-bit Windows systems to improve performance and compatibility with modern OS environments.

Broad Device Support: It handles a wide range of Infineon MCU families, including: AURIX™ (TC2xx, TC3xx, and preliminary TC49x A-step). XMC™ (XMC1000 and XMC4000 series). TriCore™, XC2000, XC16x, and XC800.

Integrated Driver Packages: Version 4.9 typically bundles the Device Access Server (DAS) package (e.g., version 7.3.7), which is necessary for JTAG and DAP communication via tools like the Infineon miniWiggler.

Enhanced UCB Programming: The tool provides dialog-based programming for User Configuration Blocks (UCB), which are critical for configuring boot modes and security settings in AURIX devices. Core Functionalities

MemTool 4.9 is engineered to perform the following operations on target microcontrollers:

Erase: Clear selectable flash sectors or the entire program and data flash areas. infineon memtool 49 new

Program: Write Intel-Hex files completely or partially into the memory.

Verify: Compare the contents of the memory module against a source file to ensure data integrity.

Protect: Set or reset chip and sector protection to secure firmware. Connectivity and Interface

To interface with a target board, MemTool 4.9 supports several communication protocols:

Standard Serial Port: RS232 connections for older or specific bootstrap loader modes.

DAS/miniWiggler: High-speed JTAG and DAP communication for advanced debugging and programming.

UART (ASC) Bootstrap Loader: Supported for XMC and some AURIX devices for simplified field programming. Usage and Best Practices

Evaluation Only: Infineon officially notes that MemTool is intended primarily for evaluation and development purposes rather than mass production lines.

Configuration Files: The tool includes ready-to-use .cfg files for most Infineon evaluation boards, simplifying the setup process for new users. Target → Erase → Erase all Confirm prompt

Updates: Developers should download the latest version directly from the Infineon Software Tools portal to ensure support for the newest microcontroller derivatives. Infineon Memtool

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.

Software Component: Infineon MemTool Version: 4.9 Release Date: 202X Category: Flash Programming Utility

Overview: MemTool 4.9 provides a graphical user interface (UI) and command line interface (CLI) for programming internal and external flash memories of Infineon Microcontrollers (AURIX™, XMC™, TRICORE™).

    Connect USB from MiniWiggler to PC.


    Old Memtool relied on a proprietary .bat style scripting that was fragile. V4.9 introduces a modern COM-API (Component Object Model) that can be controlled via Python 3.x.

    Example use case:

    import memtool_api
    device = memtool_api.connect("DAP", "TC397")
    device.load_hex("firmware_v2.hex")
    device.program(speed="fast", verify=True)
    device.lock_crc(0x80000000)
    

    This allows CI/CD pipelines (Jenkins, GitLab) to call Memtool for automated nightly builds without a human clicking the GUI.
