The Infineon Memtool 4.9 is a critical software utility designed for the production-grade handling of on-chip and on-board flash memory in Infineon Technologies microcontrollers. Released as part of the broader version 4 series, version 4.9 represents a significant transition to modern computing standards, specifically by becoming a full 64-bit application. Core Functionality and Architecture
Memtool serves as a primary interface for four essential operations: erasing, programming, verifying, and protecting selectable flash sections or entire data flash areas. It supports a wide array of file formats, most notably Intel Hex and Motorola S-Record files, which it can write directly to the target memory.
One of its most important architectural updates in version 4.9 is its reliance on the Infineon Device Access Server (DAS) package (specifically version 7.3.5 or newer), which facilitates high-speed communication between the host PC and the target hardware. Key Features of Version 4.9
64-bit Environment: Unlike previous versions, Memtool 4.9 and its successors are strictly 64-bit software, meaning they can no longer be installed or operated on 32-bit Windows systems.
Target Support: It provides comprehensive support for leading Infineon families, including:
AURIX/TriCore (TC2xx, TC3xx, and preliminary support for TC49x). XMC1000 and XMC4000 industrial microcontrollers. Legacy families like XC800, XC16x, and XC2000.
UCB & SOTA Support: Enhanced handling for User Configuration Blocks (UCB) is a hallmark of this version, including reworked UCB_SWAP configurations to support Software-Over-The-Air (SOTA) modes.
Batch Commands: The tool supports batch command operations, allowing engineers to automate repetitive programming tasks in production or testing environments. Connection Interfaces infineon memtool 49
Memtool 4.9 is versatile in its hardware requirements. For standard evaluation boards and application kits, it typically uses an onboard "wiggler." For custom hardware, it connects via:
MiniWiggler: An external hardware interface for JTAG or DAP connections.
UART (ASC) Bootstrap Loader: A serial connection method often used for initial board bring-up.
DAP and JTAG: Supported via the DAS server for real-time debugging and programming. Practical Application
In industrial and automotive development, Memtool is often used to set read and write protection on sensitive flash devices. For instance, engineers can use it to configure the Boot Mode Index (BMI), which determines how a microcontroller starts up after a reset—whether it enters a bootstrap loader mode or begins executing internal flash.

Launch MEMTool. The interface looks sparse by modern standards, but it is highly functional.
This guide assumes you are connecting via a JTAG/Debug interface (like MiniWiggler), which is the most common method.
Tip: If you are starting a new design with Infineon, skip Memtool and use Infineon Programming Tool (IPT) or a debugger like MiniWiggler + DAS. If you are stuck with legacy XC800, Memtool v4.9 is still the best free option.
