Product details
Overview
XMC1302T028X0032ABXUMA1 from Infineon is an ARM® Cortex®-M0 32-bit microcontroller designed for real-time industrial control, featuring 32 kB Flash, 16 kB SRAM, 14-channel 12-bit VADC, three fast analog comparators (ACMP), and integrated Brightness and Colour Control Unit (BCCU) for LED lighting systems.
For engineers reviewing the XMC1302T028X0032ABXUMA1 datasheet, XMC1302T028X0032ABXUMA1 pinout, XMC1302T028X0032ABXUMA1 application, or XMC1302T028X0032ABXUMA1 equivalent, key selection considerations include TSSOP-28 package compatibility, -40°C to +105°C extended temperature operation, CCU8 motor control timers, USIC serial interface flexibility (UART/I²C/I²S/SPI/LIN), and on-chip PRNG for secure firmware boot.
Technical Context
The device integrates a deterministic ARM Cortex-M0 core with hardware-accelerated math functions (CORDIC, division), enabling efficient trigonometric computation for motor vector control and digital power conversion algorithms. Its dual-sample-and-hold ADC architecture supports simultaneous sampling across two groups of channels for precise current/voltage acquisition in three-phase inverters.
Peripheral co-processing is enabled via ERU event routing, POSIF encoder interfaces, and BCCU PWM generation with gamma correction-allowing autonomous LED dimming without CPU intervention. The SCU manages clock distribution, reset sequencing, and power modes including sleep, idle, and standby with wake-up on peripheral events.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XMC1302T028X0064ABXUMA1 | 64 kB Flash, same package and peripherals - adds firmware update partitioning and larger control loop buffers. | Suitable for field-upgradable motor drives requiring dual-bank flash for seamless firmware updates. | Select when future firmware expansion or A/B firmware swapping is required; no PCB change needed. |
| XMC1302Q024X0032ABXUMA1 | VQFN-24 package, 13 ADC channels, identical Flash/SRAM/peripherals - smaller footprint, reduced I/O count. | Preferred for space-constrained LED drivers where only 12 GPIOs and 13 ADC inputs are needed. | Choose for compact designs prioritizing board area over I/O density; requires layout revision. |
Compared with XMC1302T028X0032ABXUMA1, the 64 kB variant offers headroom for feature-rich firmware without sacrificing pin compatibility, while the VQFN-24 alternative trades I/O count for miniaturization-making it optimal for cost- and size-sensitive LED modules.

FAQ
What is the maximum operating frequency and associated voltage requirement for XMC1302T028X0032ABXUMA1?
The device operates at up to 48 MHz with a core supply (VDDP) of 1.3 V ± 0.1 V and I/O supply (VDD) of 3.3 V ± 10%. This frequency is achievable across the full -40°C to +105°C range when using the internal PLL with external crystal or oscillator input. No external frequency divider is required for nominal operation.
Does XMC1302T028X0032ABXUMA1 support hardware-based encryption or secure boot features?
It includes a hardware PRNG compliant with NIST SP 800-90A for cryptographic key generation but lacks AES engines or secure boot ROM. Secure firmware validation must be implemented in software using the PRNG output and external trusted execution environment or external secure element.
Can the on-chip temperature sensor be used for system-level thermal management without external calibration?
Yes-the integrated temperature sensor (TSE) provides factory-calibrated accuracy of ±3°C from -40°C to +105°C, with linear output referenced to VDDA. It requires no user calibration and supports automatic shutdown via ORC comparator thresholds configured in firmware.
How many independent PWM outputs does the BCCU support, and what resolution is available?
The BCCU supports up to eight independent PWM channels with programmable resolution from 8 to 16 bits, adjustable gamma correction tables per channel, and hardware synchronization to avoid visible LED flicker. All outputs operate simultaneously with <1 LSB phase error across channels.
