Infineon Technologies XMC4504F100K512ACXQMA1

Overview

XMC4504F100K512ACXQMA1 from Infineon Technologies is a 32-bit ARM Cortex-M4 microcontroller with 512 KB on-chip Flash, 128 KB RAM (64 KB DSRAM + 32 KB PSRAM + 32 KB CCM), 100-pin LQFP package, and industrial temperature range (-40°C to 125°C). It integrates Ethernet MAC, USB 2.0 Full-Speed OTG with PHY, dual CAN 2.0B interfaces, six USIC channels, four 12-bit VADCs, two 12-bit DACs, CCU4/CCU8 timers for motor control, and LEDTS for HMI - deployed in servo drives, PLC I/O modules, and industrial gateways.

For engineers reviewing the XMC4504F100K512ACXQMA1 datasheet, XMC4504F100K512ACXQMA1 pinout, XMC4504F100K512ACXQMA1 application, or XMC4504F100K512ACXQMA1 equivalent, key selection criteria include Flash/RAM partitioning, integrated Ethernet+USB+CAN coexistence, CCU8-based PWM resolution for field-oriented control, and -40°C to +125°C operation in convection-cooled enclosures.

Technical Context

The XMC4504F100K512ACXQMA1 implements a tightly coupled ARM Cortex-M4 core with FPU and MPU, executing at up to 144 MHz with 4 KB instruction cache and bus matrix arbitration across dual DSRAM banks, PSRAM, and CCM. Its peripheral subsystem includes three independent clock domains: CPU (PLL-derived), peripheral (SCU-configurable dividers), and real-time (RTC/LPO), enabling deterministic timing for safety-critical control loops.

It features dual CAN nodes supporting concurrent Basic-CAN and Full-CAN message handling with hardware acceptance filtering, and six USIC channels each configurable as UART, SPI (single/dual/quad), I²C, I²S, or LIN - all with DMA-linked FIFOs and programmable baud rate generators. The EBU supports asynchronous SRAM, burst-mode NOR flash, and SDRAM interfaces up to 16-bit data width.

FAQ

Does XMC4504F100K512ACXQMA1 support JTAG debugging?

Yes, it supports ARM-standard JTAG (IEEE 1149.1) with boundary scan test capability and full CoreSight debug infrastructure. The 10-pin JTAG connector maps to dedicated pins TCK, TMS, TDI, TDO, TRST, and nSRST, enabling real-time SWO trace and 8 hardware breakpoints via compatible debug probes like Segger J-Link or ST-LINK/V2-1.

What is the maximum operating frequency of the internal PLL?

The internal PLL supports output frequencies up to 144 MHz, derived from an external crystal (1–25 MHz) or internal RC oscillator. It includes programmable pre-divider, multiplier, and post-divider stages, with lock detection and fail-safe clock switching to backup source within 10 µs upon loss of reference.

Can the VADC modules perform simultaneous sampling across multiple channels?

Yes, the four VADC modules support hardware-synchronized start triggers via CCU4/CCU8 events or external signals, enabling true simultaneous sampling across up to 32 channels (8 per VADC). Each VADC has its own result register buffer and interrupt capability, allowing concurrent conversion without CPU polling overhead.

Is the SDMMC interface compatible with eMMC 4.51 devices?

No, the SDMMC peripheral supports SD memory cards (SDSC/SDHC/SDXC) and MMC 4.2/4.3 devices only - it lacks eMMC-specific command sets (e.g., BOOT, RPMB, enhanced strobe) and does not implement the eMMC 4.51 bus timing model. Use external SPI NAND or parallel NAND controllers for eMMC-compatible storage.
