Infineon Technologies XMC1404Q048X0128AAXUMA1

Overview

XMC1404Q048X0128AAXUMA1 from Infineon Technologies is an ARM® Cortex®-M0 32-bit microcontroller with 128 KB Flash, 16 KB SRAM (with parity), and 48 MHz CPU frequency, designed for real-time industrial control including motor drive, digital power conversion, and LED lighting. It integrates dual 12-bit VADC (up to 1.1 MS/s), two CCU8 timer units for complementary PWM generation, MultiCAN+ (2 nodes, 32 message objects), and four USIC channels supporting UART/SPI/IIC/IIS up to 12 Mb/s.

For engineers reviewing the XMC1404Q048X0128AAXUMA1 datasheet, XMC1404Q048X0128AAXUMA1 pinout, XMC1404Q048X0128AAXUMA1 application, or XMC1404Q048X0128AAXUMA1 equivalent, key selection criteria include its 1.8–5.5 V operating range, -40 to 105°C ambient rating, integrated BCCU for RGB LED control, and hardware-accelerated CORDIC-based MATH coprocessor for trigonometric computation in closed-loop systems.

Technical Context

The device implements a deterministic real-time architecture with two independent CCU8 modules-each providing four 16-bit timers capable of generating complementary PWM outputs with programmable dead-time insertion, essential for three-phase inverter gate driving. Its analog subsystem includes two VADC kernels with simultaneous sampling on up to 12 analog inputs and configurable gain stages for direct current sensing.

Communication is handled via four USIC channels supporting multiple protocols concurrently: two can operate as full-duplex SPI masters/slaves at 12 Mb/s, one as IIC master/slave (400 kb/s), and one as IIS audio interface; MultiCAN+ supports CAN FD-ready frame handling with hardware message filtering and timestamping.

FAQ

What is the maximum ADC sampling rate achievable with simultaneous channel acquisition?

The dual VADC kernels support up to 1.1 million samples per second total, with simultaneous sampling across up to 12 analog inputs using two independent sample-and-hold stages. This enables synchronized current and voltage measurement in motor phase legs without inter-channel skew, critical for accurate field-oriented control loop execution at 20 kHz update rates.

Does this MCU support CAN FD or only classical CAN?

XMC1404Q048X0128AAXUMA1 implements MultiCAN+, which complies with ISO 11898-1:2015 for Classical CAN (up to 1 Mbit/s) but does not support CAN FD data-rate arbitration or flexible data-length frames. It provides 32 message objects with hardware filtering and timestamping, optimized for deterministic industrial network communication rather than automotive FD throughput.

Can the BCCU drive RGBW LED strings directly without external drivers?

No - the BCCU generates 9-channel PWM signals with programmable duty cycle, frequency, and gamma correction, but its outputs are logic-level (3.3 V) and cannot source/sink the current required by LED strings. It must be paired with external MOSFET or LED driver ICs (e.g., BC817-40 or TPS92692) to control high-power RGBW loads.

Is the SBSL (Secure Bootstrap Loader) enabled by default on this part?

No - the Secure Bootstrap Loader is an optional factory-programmed feature. XMC1404Q048X0128AAXUMA1 ships with standard bootloader unless explicitly ordered with SBSL option (part number suffix includes "SBSL"). Customers requiring AES-128 encrypted firmware updates must specify this configuration at time of order; it cannot be retrofitted post-manufacture.
