Infineon Technologies XMC4500F100K1024ACXUMA1

Overview

XMC4500F100K1024ACXUMA1 from Infineon Technologies is an ARM® Cortex®-M4 32-bit industrial microcontroller with 1024 KB on-chip Flash, 125°C operating temperature rating, and 100-pin LQFP package. It integrates Ethernet MAC (10/100 Mbit/s), USB 2.0 Full-Speed OTG with PHY, triple CAN nodes (up to 1 Mbit/s), six USIC channels supporting UART/SPI/I²C/I²S/LIN, and dual 12-bit DACs - deployed in motor control inverters requiring real-time PWM, analog feedback, and fieldbus connectivity.

For engineers reviewing the XMC4500F100K1024ACXUMA1 datasheet, XMC4500F100K1024ACXUMA1 pinout, XMC4500F100K1024ACXUMA1 application, or XMC4500F100K1024ACXUMA1 equivalent, key selection criteria include CCU8-based motor timing resolution, VADC+POSIF servo positioning capability, EBU interface for external SDRAM expansion, and industrial-grade thermal robustness up to 125°C ambient.

Technical Context

The device implements a tightly coupled memory subsystem with 64 KB DSRAM1, 64 KB DSRAM2, and 32 KB communication RAM, enabling deterministic interrupt latency for motion control loops. Its dual CCU8 units support complementary PWM generation with dead-time insertion, synchronized gate drive, and hardware fault protection via ERU-triggered emergency shutdown.

Communication architecture includes a dedicated Ethernet MAC with MII/RMII support, three independent CAN controllers compliant with ISO 11898-1, and six USIC modules each configurable as full-duplex SPI master/slave or I²C controller with clock stretching - all accessible via GPDMA channels without CPU intervention.

FAQ

What is the maximum achievable PWM frequency with hardware dead-time control on XMC4500F100K1024ACXUMA1?

The CCU8 units support PWM carrier frequencies up to 20 MHz with 150 ps resolution and programmable dead time from 1 ns to 1000 ns in 1 ns steps. This enables precise gate drive for SiC MOSFETs operating at switching frequencies above 100 kHz while maintaining shoot-through prevention across temperature and voltage variations.

Does XMC4500F100K1024ACXUMA1 include an integrated Ethernet PHY?

No, the device contains only an Ethernet MAC compliant with IEEE 802.3u (10/100 Mbit/s). External magnetics and a PHY chip (e.g., LAN8720A) are required for physical layer connectivity. The MII/RMII interface signals are routed to dedicated pins P2.0–P2.11 and support both modes via SCU configuration.

How many CAN message objects are supported, and are they shared across nodes?

The device provides 64 total message objects (MOs) distributed across three independent CAN nodes (CAN0–CAN2), with configurable allocation per node. Each MO supports full-CAN filtering, transmission priority arbitration, and automatic retransmission - enabling simultaneous CANopen device management and safety-critical messaging without CPU overhead.

Is the 1024 KB Flash memory organized in dual banks for safe firmware updates?

Yes, the Flash is partitioned into two 512 KB banks with independent erase/write control. Boot ROM supports secure bank-swapping via SWAP command, allowing background programming of one bank while executing from the other - essential for zero-downtime field upgrades in mission-critical industrial equipment.
