Infineon MemTool v4.9 is the latest major iteration of the free-of-charge software utility designed for programming and managing on-chip Flash and OTP memory on Infineon microcontrollers. This version marks a significant shift as a full 64-bit software , compatible only with Microsoft Windows 10 or newer. Key Features and Capabilities Core Functions
: Allows users to erase, program, verify, and protect on-chip memory modules. File Support : Primarily handles Intel-Hex files
, allowing for complete or partial writing of code into the memory device. Target Interfaces Standard Serial : Uses RS232/UART for basic connections. High-Speed Debug : Supports communication via the Infineon Device Access Server (DAS). Hardware Support : Compatible with onboard wigglers and external miniWiggler User Protection
: Includes features for setting and resetting Chip/Sector Protection and BMI (Boot Mode Index) configuration. Supported Device Families
MemTool 4.9 is intended for a wide range of legacy and modern Infineon architectures: AURIX™ / TriCore™ (including preliminary support for TC49x and TC3x families) families (Arm® Cortex®-M) legacy 8-bit/16-bit families Notable v4.9 Updates 64-bit Architecture
: Transitioned to 64-bit, ending support for 32-bit Windows systems. SOTA Support
: Improved support for Software-Over-The-Air (SOTA) mode for TC3xx devices, including reworked UCB (User Configuration Block) swap entries. DAS Integration : Newer sub-versions (like v4.9.3) bundle DAS server package 7.3.5 or higher for improved debugging tool connectivity. Usage and Limitations Memtool v4.9 Batch Commands
Infineon MemTool 4.9 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.
While developed by PLS Programmierbare Logik & Systeme GmbH (the creators of Universal Debug Engine or UDE), it is provided by Infineon primarily for evaluation and production support for their silicon families. Core Functional Capabilities infineon memtool 49
The tool serves as a lightweight interface for managing the memory lifecycle of embedded targets without requiring a full Integrated Development Environment (IDE).
Memory Operations: Users can perform basic operations including Erase, Program, Verify, and Protect on selectable flash sections or complete memory areas.
File Support: It primarily handles standard Intel-Hex files for writing firmware to target devices.
Hardware Interface Support: MemTool supports a variety of connection protocols depending on the target microcontroller:
DAS (Device Access Server): Used for JTAG and DAP (Device Access Port) communication via hardware like the Infineon miniWiggler.
BSL (Bootstrap Loader): Enables programming via serial (ASC/UART) interfaces.
RS232/VCOM: Standard serial communication for older or specific evaluation boards. Supported Microcontroller Families
Version 4.9 provides comprehensive support for both legacy and current high-performance Infineon silicon: Infineon MemTool v4
AURIX™ (TC2xx and TC3xx): Widely used in automotive safety and powertrain systems.
TriCore™: High-end 32-bit microcontrollers for industrial and automotive applications.
XMC™ (1000 and 4000 series): ARM® Cortex®-M based industrial microcontrollers.
Legacy Series: Support remains for XC2000, XC16x, and XC800 families. Key Usage Scenarios Infineon Memtool
The Infineon On-Chip Memory Programming Tool (Memtool) v4.9 is a free software utility designed for programming on-chip flash and OTP memory devices for Infineon microcontrollers. It is primarily used for automotive and industrial embedded development, allowing engineers to erase, program, verify, and protect memory modules. Key Capabilities and Features
Memory Operations: Allows full or partial erasing, programming, and verification of flash sections using Intel Hex-Files.
Protection Management: Users can set or reset chip and sector protection, including read/write protection with password settings. Supported Device Families:
AURIX™ / TriCore™: Including preliminary support for newer models like TC49x A-step. XMC™ Series: XMC1000 and XMC4000 families. Legacy Families: XC800, XC16x, and XC2000. Safety and Security
Communication Interfaces: Supports target connection via standard RS232 (ASC), VCOM, miniWiggler (DAP/JTAG), and the Infineon Device Access Server (DAS).
Automation: Includes support for batch commands, enabling automated programming scripts for production or testing environments. Getting Started with Memtool 4.9
Installation: The tool runs on Windows 10 or newer. Ensure the latest DAS server package (often included in the installer) is installed for JTAG/DAP communication. Configuration: Open the application and navigate to Target > Change.
Select the correct device family and chip model from the provided configuration files. Connection: Connect your target hardware (e.g., via a miniWiggler).
For AURIX devices, ensure the hardware configuration pins (HWCFG) are set to the correct mode, such as "Generic Bootstrap" if using BSL mode. Programming: Load your .hex firmware file.
Click "Connect" and, once ready, execute the "Program" command to initiate the sequence of erasing and writing to memory.

Strictly speaking, Infineon has moved on. The modern Infineon ecosystem uses MemTool 5.x (part of AURIX Toolbox) for TriCore devices and iMOTION Tool for motor drives. The original MEMTool 49 is no longer officially updated.
However, obsolete does not mean useless. Hundreds of thousands of XC886/XC878-based motor controllers, power supplies, and automotive body control modules (BCMs) remain in active service. These devices cannot be programmed by AURIX tools. As such, MEMTool 49 remains a critical utility for maintenance, repair, and reverse engineering of existing products.
