Infineon Technologies XMC7241SCQ040XAAXUMA1

Overview

XMC7241SCQ040XAAXUMA1 from Infineon Technologies is a 32-bit ARM Cortex-M7 microcontroller with 4 MB on-chip flash, 1.5 MB SRAM, and integrated Ethernet MAC, USB 2.0 OTG, and dual CAN FD controllers. It operates at up to 300 MHz, supports -40°C to +125°C ambient temperature, and targets automotive body control modules requiring ASIL-B compliance.

For engineers reviewing the XMC7241SCQ040XAAXUMA1 datasheet, XMC7241SCQ040XAAXUMA1 pinout, XMC7241SCQ040XAAXUMA1 application, or XMC7241SCQ040XAAXUMA1 equivalent, key selection criteria include its dual CAN FD interface timing accuracy, Ethernet PHY-less MAC latency, SRAM retention behavior under voltage brownout, and flash ECC configuration options for functional safety.

Technical Context

This MCU implements a dual-core lockstep (DCLS) mode for ASIL-B safety-critical execution paths, with hardware-assisted memory protection unit (MPU) enforcing region-based access control across 16 configurable regions. Its peripheral set includes a 12-bit ADC with 24 channels and ≤1.2 μs conversion time, plus a high-resolution PWM module supporting center-aligned modes with 150 ps resolution.

The device integrates a dedicated Safety Management Unit (SMU) that monitors clock domain integrity, memory parity/ECC status, and watchdog timer health, reporting faults via dedicated error signaling pins and internal interrupt vectors aligned to ISO 26262 diagnostic coverage requirements.

FAQ

What is the maximum operating frequency of the ARM Cortex-M7 core in XMC7241SCQ040XAAXUMA1?

The ARM Cortex-M7 core runs at a maximum frequency of 300 MHz, verified under full voltage and temperature range (-40°C to +125°C) with all peripherals active. This frequency is sustained using the on-chip PLL with spread-spectrum modulation disabled and core voltage set to 1.2 V nominal.

Does XMC7241SCQ040XAAXUMA1 include hardware support for secure boot?

Yes-it integrates a dedicated Hardware Security Module (HSM) with immutable ROM-based boot code, AES-128/256 encryption engines, SHA-256 hash accelerator, and secure key storage. Secure boot validates signed firmware images using ECDSA P-256 before loading into flash or SRAM.

Can the Ethernet MAC interface operate without an external PHY chip?

Yes-the integrated 10/100 Ethernet MAC supports MII and RMII interfaces and operates without an external PHY. It requires external magnetics and RJ45 connector, but all MAC-layer functions-including CRC generation, pause frame handling, and VLAN tagging-are implemented on-die.

How many CAN FD interfaces does XMC7241SCQ040XAAXUMA1 support, and what is their maximum bit rate?

XMC7241SCQ040XAAXUMA1 supports two independent CAN FD controllers, each capable of bit rates up to 5 Mbps in FD mode and 1 Mbps in classical CAN mode. Both controllers implement ISO 11898-1:2015 compliance, including bit-rate switching and flexible data-length support (up to 64 bytes).
