Infineon Memtool 49 Verified May 2026

Infineon MEMTool 49 is a development and configuration utility designed for Infineon touch-sensor and capacitive controller products (series 49). This article explains key features, verification status, setup, common workflows, troubleshooting tips, and practical recommendations for developers and integrators.

Feature Name
Sector‑49 Write Verification

Feature ID
MT‑VER‑49

Description
When the user performs a write or program operation targeting memory sector/block 49, Memtool automatically performs a read‑after‑write verification. The tool compares the data read from the device’s memory at that location against the original buffer.

Outcome

Use Case
Used during flash programming, bootloader testing, or integrity checks in automotive/industrial firmware updates.

Perform a second verify pass immediately after the first. Electrostatic discharge or ground bounce can sometimes flip a bit right after programming. A true 49-step verified device should pass twice consecutively. infineon memtool 49 verified

Deploy to production team.
Infineon Memtool 4.9 is a stable upgrade from v4.8 and a required update for anyone working with AURIX TC3xx Step D or later silicon. The speed improvements and HSM safety features alone justify the switch.
