Infineon Technologies XMC1302T028X0064ABXUMA1

Overview

XMC1302T028X0064ABXUMA1 from Infineon is an ARM® Cortex®-M0 32-bit microcontroller optimized for industrial real-time control, featuring 64 KB Flash, 16 KB SRAM, 14-channel 12-bit VADC with dual sample-and-hold, 3 fast analog comparators (ACMP), and integrated Brightness and Colour Control Unit (BCCU) for LED dimming. It targets motor control, digital power conversion, and intelligent lighting systems.

For engineers reviewing the XMC1302T028X0064ABXUMA1 datasheet, XMC1302T028X0064ABXUMA1 pinout, XMC1302T028X0064ABXUMA1 application, or XMC1302T028X0064ABXUMA1 equivalent, key selection considerations include TSSOP-28 package compatibility, -40°C to +105°C extended temperature operation, CCU8 timer support for field-oriented control, USIC serial interface flexibility (UART/I²C/I²S/SPI/LIN), and BCCU hardware acceleration for RGB LED color mixing.

Technical Context

The XMC1302T028X0064ABXUMA1 implements a deterministic real-time architecture with dedicated peripherals: CCU8 provides 8-channel PWM with dead-time insertion and emergency stop for inverter gate driving; POSIF supports quadrature encoder and Hall sensor inputs for closed-loop motor positioning. Its VADC includes two independent sample-and-hold stages enabling synchronized sampling across up to 8 channels per group.

System-level timing is managed by SCU-controlled clock generation, including a programmable PLL and multiple clock domains for peripheral gating. The MATH co-processor integrates CORDIC and integer division units to offload trigonometric and arithmetic computations from the Cortex-M0 core-critical for servo loop execution within tight cycle budgets.

FAQ

What is the maximum operating frequency of the XMC1302T028X0064ABXUMA1?

The XMC1302T028X0064ABXUMA1 operates at up to 48 MHz from its internal PLL, which accepts input clocks from 1–20 MHz crystals or external oscillators. This frequency is sustained across the full -40°C to +105°C range with 2.7–5.5 V supply, and all peripherals-including CCU8 and VADC-are fully functional at this speed without timing derating.

Does this MCU support hardware-based AES encryption?

No, the XMC1302T028X0064ABXUMA1 does not include dedicated AES hardware acceleration. Security functions are limited to the PRNG for cryptographic key seeding and WDT-based system integrity monitoring. For AES-128/256 implementation, software libraries must be used-Infineon provides optimized CMSIS-compliant routines in the DAVE™ IDE.

Can the BCCU control more than three LED channels simultaneously?

Yes-the BCCU supports up to four independent PWM channels (RGBW configuration) with synchronized timing, gamma correction, and automatic current balancing. Each channel drives one LED string via external MOSFETs; the unit manages cross-fade transitions and thermal derating autonomously without CPU intervention.

Is the TSSOP-28 package RoHS and REACH compliant?

Yes, XMC1302T028X0064ABXUMA1 in PG-TSSOP-28-8 packaging meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free matte tin termination and halogen-free molding compound. Full compliance documentation, including substance declarations and test reports, is available via Infineon's Eco Reports portal.
