Overview

XMC4502F100F768ACXQMA1 from Infineon Technologies is an ARM® Cortex®-M4 32-bit industrial microcontroller with 768 KB Flash, 100 MHz CPU clock, and LQFP-100 package. It integrates Ethernet MAC, USB 2.0 OTG (with PHY), dual CAN nodes, six USIC channels (supporting UART/SPI/I²C/I²S/LIN), four 12-bit VADCs (8-channel each), two 12-bit DACs, CCU4/CCU8 timers for motor control, and hardware CRC engine. Used in real-time industrial motion control systems requiring deterministic timing and multi-protocol connectivity.

Technical Context

The XMC4502F100F768ACXQMA1 implements a tightly coupled ARM Cortex-M4 core with FPU and MPU, executing Thumb-2 instructions at up to 100 MHz with 4 KB instruction cache. Its memory subsystem includes 768 KB on-chip Flash (with ECC), 64 KB DSRAM, 64 KB PSRAM, and 32 KB communication RAM, managed via a bus matrix supporting concurrent access by CPU, DMA, and peripherals.

Real-time peripheral control is enabled by dual CCU8 units (each with 4 capture/compare channels and dead-time insertion), four CCU4 timers, two POSIF interfaces for servo position feedback, and ERU for asynchronous event routing. Analog subsystem comprises four independent VADC modules (12-bit, 8-channel, out-of-range comparator per channel) and a Delta-Sigma Demodulator for high-resolution sensor signal acquisition.

FAQ

Does XMC4502F100F768ACXQMA1 include an integrated USB PHY?

Yes - it integrates a full-speed USB 2.0 OTG PHY compliant with USB specification revision 2.0. This eliminates the need for external transceivers and supports both host and device modes. The PHY connects directly to the USB connector via differential D+/D− lines and requires only standard 1.5 kΩ pull-up/pull-down resistors for enumeration.

What is the maximum operating frequency of the CCU8 timer units?

The CCU8 units operate synchronously with the peripheral clock (PCLK), which is derived from the CPU clock (100 MHz) and configurable via SCU dividers. With PCLK set to 100 MHz, CCU8 achieves 1 ns resolution and supports PWM frequencies up to 50 MHz in single-shot mode or 25 MHz in complementary mode with dead-time insertion - sufficient for 20 kHz motor switching with 100 ns dead-time granularity.

How many VADC modules does XMC4502F100F768ACXQMA1 support, and what is their shared resource constraint?

It integrates four independent VADC modules (VADC0–VADC3), each with 8 input channels and dedicated result registers. All four share a single conversion clock source and one common arbitration unit - meaning simultaneous conversions across modules require explicit scheduling via the VADC group sequencer to avoid arbitration conflicts and ensure deterministic sampling timing.

Is the Ethernet MAC interface capable of full-duplex 100 Mbit/s operation without external PHY?

No - the XMC4502F100F768ACXQMA1 includes only the Ethernet MAC layer (IEEE 802.3-compliant), not the physical layer. An external 10/100 Mbit/s PHY (e.g., LAN8720A or KSZ8081RNB) is required and connected via RMII or MII interface. The MAC supports both RMII (5-pin) and MII (16-pin) modes, with ETH_MDC/MDIO used for PHY register configuration.
