Infineon Technologies XMC4800F100K2048AAXQMA1

Overview

XMC4800F100K2048AAXQMA1 from Infineon Technologies is an ARM® Cortex®-M4 32-bit microcontroller with 2048 KB on-chip Flash, 128 KB SRAM, and 100-pin LQFP package. It integrates Ethernet MAC (10/100 Mbit/s), EtherCAT Slave interface (100 Mbit/s), six USIC channels supporting UART/SPI/I²C/I²S/LIN, and dual 12-bit DACs. Designed for industrial motor control and power conversion systems requiring deterministic real-time response and fieldbus connectivity.

For engineers reviewing the XMC4800F100K2048AAXQMA1 datasheet, XMC4800F100K2048AAXQMA1 pinout, XMC4800F100K2048AAXQMA1 application, or XMC4800F100K2048AAXQMA1 equivalent, key selection criteria include EtherCAT slave timing compliance, CCU8-based PWM resolution (150 ps), VADC sampling rate (2.5 MSPS per converter), and EBU SDRAM interface support for external memory expansion in HMI or gateway designs.

Technical Context

The device implements a dual-bus matrix architecture with separate instruction (ICode) and data (DCode) buses to the CPU subsystem, enabling concurrent instruction fetch and data access. Its SCU configures clock domains including a PLL with programmable multiplication (up to ×160) and division ratios, supporting precise 144 MHz core operation from a 12 MHz crystal.

EtherCAT functionality relies on dedicated hardware: two MII ports, eight FMMUs, eight Sync Managers, and distributed clock synchronization with ±10 ns jitter tolerance. The CCU8 units provide complementary PWM outputs with dead-time insertion and emergency stop inputs-critical for IGBT gate driving in servo inverters.

FAQ

Does XMC4800F100K2048AAXQMA1 support JTAG debugging?

Yes, it supports IEEE 1149.1-compliant JTAG boundary scan and debug access via TCK/TMS/TDI/TDO/TRST pins. The embedded SW-DP interface also enables Serial Wire Debug with real-time trace capability through the ETM module, allowing non-intrusive code profiling and hardware breakpoint setting during live EtherCAT operation.

What is the maximum operating frequency of the CPU core?

The ARM Cortex-M4 core operates at up to 144 MHz, achieved via the on-chip PLL configured with a 12 MHz crystal input and multiplication factor of ×12. This frequency is sustained across the full −40 °C to +125 °C temperature range with appropriate VDD supply decoupling and thermal management per Infineon's AN2017-07 guidelines.

Can the USB OTG interface operate in host mode?

Yes, the integrated USB 2.0 Full-Speed OTG controller supports both device and host modes. In host mode, it can enumerate and communicate with USB mass storage devices (e.g., firmware update sticks) or HID peripherals, using the on-chip PHY-no external transceiver required. VBUS detection and session request protocol are handled in hardware.

Is the Flash memory capable of EEPROM emulation?

Yes, Infineon provides the DAVE™ Flash Driver library that implements wear-leveling and atomic write routines for emulating EEPROM functionality in designated Flash sectors. This enables reliable parameter storage (e.g., calibration data, motor profiles) with >100,000 erase/write cycles and data retention exceeding 20 years at 125 °C junction temperature.
