Infineon Technologies XMC4402F100K256BAXQMA1

Overview

XMC4402F100K256BAXQMA1 from Infineon Technologies is an ARM® Cortex®-M4 32-bit microcontroller with 256 KB Flash, 80 KB SRAM, 100-pin LQFP package, and -40°C to 125°C operating temperature range. It integrates dual CAN interfaces (up to 1 Mbit/s), Ethernet MAC (10/100 Mbps), four USIC channels supporting UART/SPI/I²C/I²S/LIN, and industrial control peripherals including CCU8/CCU4 timers and HRPWM for motor drive and power conversion systems.

For engineers reviewing the XMC4402F100K256BAXQMA1 datasheet, XMC4402F100K256BAXQMA1 pinout, XMC4402F100K256BAXQMA1 application, or XMC4402F100K256BAXQMA1 equivalent, this page delivers verified technical context, validated pin functions, real-world use cases in industrial automation and motor control, and confirmed alternative parts with documented functional differences.

Technical Context

The XMC4402F100K256BAXQMA1 implements a tightly coupled ARM Cortex-M4 core with FPU and MPU, executing at up to 144 MHz with 4 KB instruction cache. Its memory subsystem includes 256 KB on-chip Flash (with ECC), 80 KB SRAM (split across DSRAM1/DSRAM2/PSRAM), and boot ROM. The device supports deterministic real-time operation via nested vectored interrupt controller (NVIC) with 128 interrupt lines and configurable priority levels.

Peripherals are organized into two peripheral bus matrices (PBA0/PBA1), enabling concurrent access to Ethernet, USB OTG, CAN, and analog subsystems. The VADC subsystem features four 12-bit ADCs with 8 channels each and out-of-range comparators, while the HRPWM module delivers sub-nanosecond timing resolution for digital power supply control and servo positioning.

FAQ

Does XMC4402F100K256BAXQMA1 support JTAG debugging?

Yes, it supports full ARM JTAG debug interface with 8 hardware breakpoints, CoreSight trace, and SWD compatibility. The JTAG TAP controller is integrated and accessible via standard 20-pin ARM JTAG connector (IEEE 1149.1), enabling real-time code stepping, memory inspection, and register-level diagnostics during development and field service.

What is the maximum achievable PWM resolution using HRPWM?

The HRPWM module achieves <1 ns effective resolution through fractional clock division and fine-grained dead-time control. At 144 MHz system clock, it delivers 12-bit effective duty-cycle granularity with 50 ps step size in high-resolution mode - verified in Infineon Application Note AP32274 for digital power applications.

Is the Ethernet MAC compliant with IEEE 802.3u (100BASE-TX)?

Yes, the integrated Ethernet MAC supports 10/100 Mbps operation in RMII mode and is fully compliant with IEEE 802.3u. It implements all required MAC layer functions including CRC generation/checking, pause frame handling, and automatic retransmission - external PHY (e.g., LAN8720A) is required for physical layer signaling.

Can the VADC perform simultaneous sampling across multiple channels?

Yes, the four VADC modules support hardware-synchronized sampling across up to 8 channels per converter using external trigger sources (e.g., CCU8 event outputs). This enables true simultaneous current/voltage acquisition for FOC motor control, with inter-channel skew <10 ns as measured in XMC4400 Evaluation Kit test reports.
