Product details
Overview
XMC1302T028X0128ABXUMA1 from Infineon Technologies is an ARM® Cortex®-M0 32-bit microcontroller designed for real-time industrial control, featuring 128 KB Flash, 16 KB SRAM, 14-channel 12-bit VADC, 3 analog comparators (ACMP), and integrated Brightness and Colour Control Unit (BCCU) for LED lighting systems. It operates across -40°C to +105°C and uses a PG-TSSOP-28-8 package.
For engineers reviewing the XMC1302T028X0128ABXUMA1 datasheet, XMC1302T028X0128ABXUMA1 pinout, XMC1302T028X0128ABXUMA1 application, or XMC1302T028X0128ABXUMA1 equivalent, key selection criteria include motor control timing precision, LED dimming resolution via BCCU, ADC channel count and sampling rate, CCU8/CCU4 peripheral availability, and industrial temperature grade compliance.
Technical Context
The device implements a deterministic real-time architecture with dual capture/compare units: CCU8 for high-precision motor phase control (≤1 ns resolution) and CCU4 for general-purpose timing. Its VADC supports simultaneous sampling on two groups (G0/G1) with hardware-triggered conversion sequences.
Integrated peripherals include two USIC channels supporting UART, SPI, I²C, I²S, and LIN protocols; ERU for asynchronous event routing; MATH co-processor with CORDIC and division units; and SPD/SWD debug interfaces. The BCCU enables PWM-based RGB LED color mixing with independent channel resolution up to 16 bits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar industrial microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XMC1302T028X0200ABXUMA1 | 200 KB Flash (vs. 128 KB), same SRAM, package, and peripheral set | Supports larger firmware images with multiple communication stacks (e.g., CAN + USB + Ethernet MAC) | Select when firmware size exceeds 128 KB or future-proofing for feature expansion is required |
| XMC1302T038X0128ABXUMA1 | 38-pin TSSOP package, adds 2 extra ADC channels (16 total) and 2 additional GPIOs | Enables direct connection to more sensors or higher I/O density in space-constrained industrial modules | Select when >22 GPIOs or full 16-channel ADC coverage is needed without external multiplexing |

FAQ
What debug interfaces does XMC1302T028X0128ABXUMA1 support?
The device supports ARM Serial Wire Debug (SWD) via dedicated SWDIO and SWCLK pins, plus Single-Pin Debug (SPD) mode that repurposes one GPIO for full debug functionality. Both interfaces enable flash programming, real-time variable inspection, and breakpoint debugging without requiring JTAG headers.
Does this MCU include hardware security features?
It includes a boot ROM with configurable flash lock bits, write protection for memory sectors, and a pseudo-random number generator (PRNG) compliant with NIST SP 800-90A. No cryptographic accelerators or secure boot engines are integrated - external secure elements are recommended for certified secure boot implementations.
Can the BCCU drive RGB LEDs directly without external drivers?
No. The BCCU generates high-resolution PWM signals but lacks integrated power switches; it requires external MOSFET or LED driver ICs (e.g., BC817-40 or TPS92661) to source/sink LED current. Its outputs are logic-level (3.3 V CMOS) with 20 mA max sink/source per pin.
What is the maximum ADC sampling rate achievable with hardware triggers?
With hardware-triggered conversions and no oversampling, the VADC achieves up to 1.5 MSPS aggregate throughput across all enabled channels. Individual channel sampling rate depends on clock configuration and group setup but reaches 1.25 MS/s in single-channel mode using the internal 48 MHz clock divider.
