Infineon Technologies XMC1401Q048F0128AAXUMA1

Overview

XMC1401Q048F0128AAXUMA1 from Infineon Technologies is an ARM® Cortex®-M0 32-bit microcontroller designed for real-time industrial control, featuring 48 MHz CPU frequency, 128 KB Flash with ECC, 16 KB SRAM with parity, and operation across -40°C to 105°C ambient. It integrates dual 12-bit VADC (up to 1.1 MS/s), two CCU8 timer units for complementary PWM generation, and four USIC channels supporting UART/SPI/IIC/IIS up to 12 Mb/s - deployed in motor drive inverters and digital power supplies.

For engineers reviewing the XMC1401Q048F0128AAXUMA1 datasheet, XMC1401Q048F0128AAXUMA1 pinout, XMC1401Q048F0128AAXUMA1 application, or XMC1401Q048F0128AAXUMA1 equivalent, key selection criteria include its 48-pin LQFP package, 1.8–5.5 V supply range, integrated POSIF for encoder interfacing, BCCU for LED color/brightness control, and MultiCAN+ support for distributed industrial networks.

Technical Context

The device implements a deterministic real-time architecture with two independent CCU8 modules (each with four 16-bit timers) enabling synchronized high-side/low-side gate driving for three-phase motor control. Its dual VADC subsystem supports simultaneous sampling across 12 analog inputs with programmable gain and two-stage sample-and-hold.

Communication is handled via four USIC channels - configurable as UART, SPI (single/dual/quad), IIC, IIS, or LIN - alongside a dedicated MultiCAN+ controller with 2 nodes and 32 message objects, supporting up to 1 MBaud CAN FD-compatible framing. The on-chip debug interface uses ARM Serial Wire Debug (SWD) with 4 breakpoints and 2 watchpoints.

FAQ

What is the maximum operating frequency of the ARM Cortex-M0 core in this device?

The XMC1401Q048F0128AAXUMA1 runs its ARM Cortex-M0 processor core at a maximum frequency of 48 MHz, delivering 0.84 DMIPS/MHz performance per Dhrystone 2.1 benchmark. This speed is sustained across the full -40°C to +105°C industrial temperature range with appropriate voltage supply (1.8–5.5 V).

Does this microcontroller support CAN FD or only classical CAN?

This device implements MultiCAN+, which supports Classical CAN (Basic-CAN and Full-CAN) up to 1 MBaud but does not support CAN FD data-rate acceleration or extended frame formats. It provides 2 CAN nodes and 32 message objects with hardware filtering and priority-based transmission scheduling.

How many analog-to-digital converter channels are available, and what is their resolution?

The device integrates two 12-bit VADC kernels supporting up to 12 analog input channels total. Each kernel features two sample-and-hold stages and achieves up to 1.1 million samples per second, with programmable gain and 0 V to 5.5 V input voltage range referenced to VDDA.

Is the bootloader accessible via a single-pin interface, and what protocols does it support?

Yes - the device includes a single-pin bootloader (SPB) accessible via UART using the Infineon BootROM protocol. It supports firmware updates over UART without requiring JTAG/SWD, and optionally integrates the Secure Bootstrap Loader (SBSL) for authenticated code loading and flash encryption key management.
