Infineon Technologies XMC7231SCQ024XABXUMA1

Overview

XMC7231SCQ024XABXUMA1 from Infineon Technologies is a 32-bit ARM Cortex-M7 microcontroller with 2 MB on-chip flash, 512 KB SRAM, and integrated Ethernet MAC, USB 2.0 OTG, and dual CAN FD controllers. It targets real-time industrial control applications requiring deterministic timing, secure boot, and functional safety support up to IEC 61508 SIL3.

For engineers reviewing the XMC7231SCQ024XABXUMA1 datasheet, XMC7231SCQ024XABXUMA1 pinout, XMC7231SCQ024XABXUMA1 application, or XMC7231SCQ024XABXUMA1 equivalent, key selection criteria include its dual-core lockstep capability, 240 MHz CPU frequency, hardware crypto acceleration (AES-128/256, SHA-256, TRNG), and AEC-Q100 Grade 2 qualification for automotive-grade reliability in harsh environments.

Technical Context

The device implements a dual-core lockstep (DCLS) configuration where two identical Cortex-M7 cores execute identical instructions with cycle-synchronous comparison to detect transient faults. It integrates a 16-channel DMA controller with scatter-gather support and a configurable peripheral interconnect matrix (PIM) enabling low-latency, parallel peripheral access without CPU intervention.

Timing control is managed via a dedicated Real-Time Clock (RTC) with tamper detection, a 32-bit system timer (SysTick), and four independent 32-bit general-purpose timers with quadrature encoder and PWM capture capabilities. The memory subsystem includes ECC protection on both flash and SRAM, and a 16 KB instruction cache with parity.

FAQ

What is the maximum operating frequency of the Cortex-M7 core in XMC7231SCQ024XABXUMA1?

The device operates at a maximum CPU frequency of 240 MHz. This is achieved using an on-chip PLL with spread-spectrum modulation to reduce EMI emissions. The core runs from a dedicated 1.2 V supply domain, and frequency scaling is supported via dynamic voltage and frequency scaling (DVFS) registers accessible through the power control unit (PCU).

Does XMC7231SCQ024XABXUMA1 support secure boot with public-key verification?

Yes. The device implements secure boot using RSA-2048 or ECDSA-P256 signature verification against firmware images stored in flash. Public keys are provisioned in one-time-programmable (OTP) memory during manufacturing, and the boot ROM validates signatures before executing any user code. Boot mode selection is controlled by dedicated pins with internal pull-ups.

How many CAN FD interfaces does XMC7231SCQ024XABXUMA1 integrate, and what is their maximum bit rate?

XMC7231SCQ024XABXUMA1 integrates two independent CAN FD controllers, each supporting data phase bit rates up to 5 Mbps. Both controllers feature hardware message filtering, transmit queue prioritization, and automatic retransmission. They share no resources with the Ethernet or USB peripherals, enabling simultaneous high-bandwidth CAN FD and Ethernet traffic.

Is the Ethernet MAC compliant with IEEE 802.3 and does it support IEEE 1588 Precision Time Protocol?

Yes. The integrated Ethernet MAC supports IEEE 802.3-2018 (10/100BASE-TX) and includes full IEEE 1588-2008 v2 hardware timestamping with sub-100 ns resolution. Timestamp registers are accessible via dedicated APB peripherals, and the MAC supports PTP event message filtering and transparent clock functionality for industrial time-sensitive networking.
