Product details

Overview

XMC1402Q040X0128AAXUMA1 from Infineon Technologies is an ARM® Cortex®-M0 32-bit microcontroller with 128 KB Flash, 16 KB SRAM, 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, and four USIC channels supporting UART/SPI/IIC/IIS up to 12 Mb/s.

For engineers reviewing the XMC1402Q040X0128AAXUMA1 datasheet, XMC1402Q040X0128AAXUMA1 pinout, XMC1402Q040X0128AAXUMA1 application, or XMC1402Q040X0128AAXUMA1 equivalent, key selection criteria include its 96 MHz CCU8 timer capability for high-resolution motor phase control, 1.8–5.5 V wide supply range enabling direct interface with industrial sensors and actuators, and integrated BCCU for RGB LED brightness/color sequencing in HMI systems.

Technical Context

The XMC1402Q040X0128AAXUMA1 implements a deterministic real-time architecture centered on dual CCU8 modules-each with four 16-bit timers capable of generating complementary PWM outputs with programmable dead-time insertion and fault protection. Its analog subsystem includes two independent VADC kernels with 12-bit resolution, dual sample-and-hold stages, and 0–5.5 V input range, enabling direct sensing of unconditioned industrial voltage rails.

Communication is handled by four USIC channels supporting concurrent protocols: two can operate as full-duplex SPI masters/slaves at up to 12 Mb/s, one as IIC master/slave (400 kb/s), and one as IIS audio interface (12 Mb/s). The device supports single-pin bootloader activation and ARM Serial Wire Debug (SWD) with 4 breakpoints and 2 watchpoints.

Equivalent & Alternatives

The following parts are listed as comparable options for similar industrial microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STM32G474RET6	ARM Cortex-M4F @ 170 MHz, 512 KB Flash, no integrated BCCU or POSIF; requires external gate driver ICs for high-side switching.	Targets higher-performance FOC with floating-point math but lacks hardware motor position decoding and LED-specific peripherals.	Select when advanced DSP features (e.g., hardware FFT) are required and external component count is acceptable.
XMC4402F100K256ABXUMA1	ARM Cortex-M4 @ 120 MHz, 256 KB Flash, CCU8+CCU4+POSIF+BCCU, but in LQFP-100 package - larger footprint and higher cost.	Offers extended peripheral set and memory for complex multi-axis motion control, not optimized for compact LED/lighting designs.	Select when scaling beyond single-motor control or requiring additional CAN FD or Ethernet connectivity.

Compared with STM32G474RET6 and XMC4402F100K256ABXUMA1, the XMC1402Q040X0128AAXUMA1 provides optimal integration density for cost-sensitive industrial motor and LED applications, balancing CCU8 precision, VADC speed, and BCCU efficiency in a compact VQFN-40 package without sacrificing functional safety readiness.

FAQ

What is the maximum operating frequency of the XMC1402Q040X0128AAXUMA1 CPU core?

The XMC1402Q040X0128AAXUMA1 features an ARM Cortex-M0 processor core rated for 48 MHz operation. This frequency is sustained across the full -40 °C to +105 °C ambient temperature range and 1.8–5.5 V supply voltage, with performance verified per Dhrystone 2.1 benchmark at 0.84 DMIPS/MHz.

Does this microcontroller support hardware-based motor commutation without CPU intervention?

Yes. The device integrates two POSIF (Position Interface) modules that directly decode Hall-effect and quadrature encoder signals, and two CCU8 units with hardware-triggered complementary PWM generation. These peripherals enable fully autonomous BLDC/PMSM commutation cycles using ERU event routing, eliminating CPU polling or interrupt servicing.

Can the VADC perform simultaneous sampling across multiple channels?

Yes. The dual VADC kernels support synchronized sampling across up to 12 analog inputs using shared trigger sources (e.g., CCU8 period match). Each kernel includes two sample-and-hold stages, allowing true simultaneous capture of current and voltage feedback signals for three-phase inverter control.

Is the XMC1402Q040X0128AAXUMA1 qualified for automotive applications?

The device is specified for -40 °C to +105 °C operation and meets AEC-Q100 stress test requirements for Grade 2 temperature range. While not officially AEC-Q100 certified out-of-box, its electrical characteristics, package robustness (VQFN-40 wettable flanks), and built-in ECC/parity protections align with automotive power module design practices.
