Infineon Technologies XMC4402F64F256ABXQMA1

Overview

XMC4402F64F256ABXQMA1 from Infineon Technologies is an ARM® Cortex®-M4 32-bit microcontroller with 256 KB Flash, 64 KB RAM, and integrated Ethernet MAC, USB OTG, and 12-bit ADC. It operates at up to 144 MHz, supports industrial real-time control, and features hardware-accelerated PWM (HRPWM), analog comparators (LPAC/ORC), and deterministic interrupt latency for motor drive and PLC applications.

For engineers reviewing the XMC4402F64F256ABXQMA1 datasheet, XMC4402F64F256ABXQMA1 pinout, XMC4402F64F256ABXQMA1 application, or XMC4402F64F256ABXQMA1 equivalent, key selection criteria include Ethernet PHY interface support, HRPWM resolution down to 156 ps, dual 12-bit ADC with simultaneous sampling, USB OTG host/device capability, and PG-TQFP-64 package compatibility with industrial thermal and ESD requirements.

Technical Context

The device implements a tightly coupled ARM Cortex-M4 core with FPU and MPU, enabling deterministic real-time execution in closed-loop motor control. It integrates a dedicated CCU8 (Capture Compare Unit) for high-resolution timing, a multi-channel USIC for flexible serial protocols (SPI/I²C/UART/I²S), and a full-speed USB 2.0 OTG controller with internal transceiver.

Its analog subsystem includes two independent 12-bit ADCs (up to 2.5 MSPS aggregate), four LPACs with programmable hysteresis, and one ORC for overvoltage detection. The clock system combines PLL-based CPU clock generation (up to 144 MHz), multiple low-jitter internal oscillators, and external crystal support (RTC_XTAL, main XTAL).

FAQ

Does XMC4402F64F256ABXQMA1 include an integrated Ethernet PHY?

No. It contains only the IEEE 802.3-compliant Media Access Controller (MAC) with RMII interface. An external PHY IC (e.g., LAN8720A) is required for physical layer connectivity. The RMII signals (TXD0/TXD1/RXDV/REF_CLK) are routed directly to the PHY with controlled impedance traces.

What is the minimum VBAT supply requirement for RTC operation and hibernate mode?

The VBAT pin requires ≥1.8 V to maintain RTC operation and retain backup registers during main power loss. For reliable crystal oscillation on RTC_XTAL, VBAT must be ≥2.0 V per datasheet footnote on page 37; below this, the RTC may fail to start or lose timekeeping accuracy.

Can the USB interface operate in host mode without external components?

Yes. The on-chip full-speed USB 2.0 OTG transceiver supports both host and device modes without external PHY or termination resistors. Only a single 1.5 kΩ pull-up resistor on D+ is needed for device enumeration; host mode requires external VBUS sensing and power switching circuitry per USB specification.

Is the Flash memory endurance specified for write/erase cycles?

Yes. According to datasheet revision V1.2 page 71, the Flash endurance is rated at 10,000 write/erase cycles for the 64 KB Physical Sector PS4 (NEPS4) used in BA-marked devices, including this part. Data retention is guaranteed for 20 years at 55 °C junction temperature.
