Article: Infineon MemTool 49 — Overview, Features, and How to Use

Infineon MemTool is a Windows-based utility for programming and configuring Infineon microcontroller and memory devices. “MemTool 49” typically refers to version 4.9 of the tool (shortened as “49”), which introduced bug fixes, UI refinements, and support updates for specific Infineon devices. This article summarizes what MemTool 4.9 offers, how to install and use it, common workflows, troubleshooting tips, and alternatives.

Why Use MEMTool 49 in the Modern Era?

Many engineers ask: “Why not just use a universal IDE like Keil or a debugger like J-Link Commander?” infineon memtool 49

The answer lies in specialization. Infineon MEMTool 49 offers distinct advantages: Article: Infineon MemTool 49 — Overview, Features, and

  1. Standalone Operation: You do not need a full IDE installation (like Keil uVision or Tasking). MEMTool is lightweight, runs on older Windows systems (XP to 10), and launches in seconds.
  2. Bootstrap Loading Mastery: The XC800 series has a unique boot ROM. MEMTool handles the bootstrap protocol perfectly, allowing you to program a completely blank device via a simple UART.
  3. Security and HSM Access: It provides granular control over flash security bits, read/write protection, and password protection for the XC800 family.
  4. Production Programming: MEMTool supports command-line parameters and scripting via batch files, making it ideal for integrating into automated production testers.
  5. ECC Handling: It correctly manages Error Correction Code (ECC) regions in XC16x and XC2000 devices, which generic tools often mishandle.

Step 3: Initial Configuration of MEMTool 49

Launch MEMTool. The interface looks sparse by modern standards, but it is highly functional. Standalone Operation: You do not need a full

  1. Select Device: Go to Target > Select Target Device. Choose your exact part number (e.g., XC886CLM-16FF).
  2. Configure Interface: Go to Target > Hardware Configuration.
    • Interface Type: Choose Serial Bootstrap Loader (for XC800) or Serial Monitor (for C166).
    • COM Port: Select your serial port (e.g., COM3).
    • Baud Rate: 115200 is common, but start with 19200 or 57600 for stability.
  3. Target System Clock: Enter your target’s external oscillator frequency (e.g., 4 MHz, 8 MHz). This is crucial for baud rate calculation.
