Infineon Technologies XMC1401Q048F0064AAXUMA1

Overview

XMC1401Q048F0064AAXUMA1 from Infineon Technologies is an ARM® Cortex®-M0 32-bit microcontroller with 48 MHz CPU frequency, 64 KB Flash, 16 KB SRAM, and industrial temperature range (−40 °C to 105 °C). It integrates dual 12-bit VADC (up to 1.1 MS/s), two CCU4 timer units for PWM generation, USIC modules supporting UART/SPI/IIC/IIS, and LEDTS for touch/LED control - deployed in motor control, digital power conversion, and HMI systems.

For engineers reviewing the XMC1401Q048F0064AAXUMA1 datasheet, XMC1401Q048F0064AAXUMA1 pinout, XMC1401Q048F0064AAXUMA1 application, or XMC1401Q048F0064AAXUMA1 equivalent, key selection criteria include flash size (64 KB), LQFP-48 package compatibility, −40 °C to 105 °C operating range, dual VADC capability, and integrated CCU4/CCU8 timers for real-time motor control timing.

Technical Context

This device belongs to the XMC1400 AA-Step series targeting deterministic real-time control. Its ARM Cortex-M0 core delivers 0.84 DMIPS/MHz at 48 MHz, supported by a dedicated MATH coprocessor for CORDIC-based trigonometric calculations and 32-bit division - critical for motor vector control algorithms.

The peripheral set includes two USIC modules (4 channels total) configurable as UART, SPI (single/dual/quad), IIC, IIS, or LIN; dual 12-bit VADCs with sample-and-hold and programmable gain; and two CCU4 units (each with four 16-bit timers) enabling synchronized PWM generation with dead-time insertion for three-phase inverter gate driving.

Key Specifications

Pinout & Package

FAQ

What is the maximum ADC sampling rate supported by XMC1401Q048F0064AAXUMA1?

The device supports up to 1.1 million samples per second (1.1 MS/s) using its dual 12-bit VADC modules with sample-and-hold stages. This rate is achievable in single-channel mode with minimal conversion latency and is validated across the full −40 °C to 105 °C operating range per Infineon's datasheet Section 3.2.2.

Does XMC1401Q048F0064AAXUMA1 include hardware-based cryptographic acceleration?

No, this variant does not integrate hardware cryptographic accelerators such as AES or SHA engines. It relies on software libraries for security functions. Secure Bootloader (SBSL) is optional and implemented via ROM-based secure bootstrap loader - verified boot is supported, but encryption operations execute in software on the Cortex-M0 core.

Can the USIC modules operate simultaneously as UART and SPI on the same device?

Yes - the two USIC modules (USIC0 and USIC1) are fully independent. One can be configured as a 12 Mb/s UART for debug/logging while the other runs dual-SPI at 12 Mb/s for encoder or sensor interface, with no resource contention, as confirmed in the Reference Manual Chapter 12 and Datasheet Section 3.3.6.1.

What is the purpose of the ERU peripheral in this microcontroller?

The Event Request Unit (ERU) provides hardware event routing between peripherals without CPU intervention. It supports up to 2×4 channels for cross-triggering - for example, linking a CCU4 timer overflow to initiate ADC conversion or synchronizing POSIF quadrature events with BCCU LED dimming updates - reducing interrupt load and jitter in real-time control loops.
