Product details

Overview

XMC1202T028X0064AAXUMA1 from Infineon Technologies is an ARM® Cortex™-M0 32-bit microcontroller optimized for LED lighting and human-machine interface (HMI) applications, featuring 64 KB on-chip Flash, 16 KB SRAM, and integrated analog peripherals including a 12-bit VADC with up to 16 channels and two LED timer subsystems (LEDTS0/LEDTS1). It operates at up to 48 MHz and supports serial wire debug (SWD).

For engineers reviewing the XMC1202T028X0064AAXUMA1 datasheet, XMC1202T028X0064AAXUMA1 pinout, XMC1202T028X0064AAXUMA1 application, or XMC1202T028X0064AAXUMA1 equivalent, this page delivers verified electrical parameters, package mapping, validated pin functions, and real-world use context for industrial embedded design and lighting control systems.

Technical Context

The device integrates a single-core ARM Cortex-M0 CPU running at up to 48 MHz, coupled with a dedicated LED timer subsystem supporting PWM dimming with phase-shifted outputs and dead-time insertion-critical for multi-channel LED driver control. Its analog subsystem includes a 12-bit voltage ADC (VADC) with hardware sequencer, two analog comparators (ACMP), and an out-of-range comparator (ORC) for fast overvoltage/undervoltage detection.

Peripherals are organized via AHB-Lite and APB buses, with USIC modules supporting UART, SPI, I²C, and I²S protocols, and CCU4 timers delivering precise capture/compare functionality for motor control or power conversion timing. The device uses a fixed 28-pin TSSOP package with 22 GPIOs, all 5 V-tolerant.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
XMC1202T038X0064AAXUMA1	38-pin TQFP package, adds 6 additional GPIOs and one extra USIC channel - no change in Flash/SRAM or core peripherals.	Suitable for designs requiring more I/O expansion or dual serial interfaces (e.g., simultaneous UART + I²C).	Select when board layout allows larger package and additional peripheral routing is needed.
XMC1100T016F0032ABXUMA1	ARM Cortex-M0 core, 32 KB Flash, 16 KB SRAM, but lacks LEDTS and ORC - only one USIC module and no VADC sequencer.	Targeted at basic sensor node or simple control tasks where LED-specific timing and analog monitoring are not required.	Choose only if cost reduction is primary and LEDTS/VADC features are unused in the design.

Compared with XMC1202T028X0064AAXUMA1, the T038 variant offers I/O scalability without sacrificing LED control capability, while the XMC1100 variant trades specialized lighting features for lower gate count and price-making it unsuitable for closed-loop LED or HMI applications requiring hardware-accelerated timing.

FAQ

What is the maximum operating frequency of the XMC1202T028X0064AAXUMA1?

The XMC1202T028X0064AAXUMA1 operates at a maximum CPU clock frequency of 48 MHz, derived from its internal DCO or external crystal oscillator. This frequency is fully supported across the entire industrial temperature range (–40°C to +125°C) and enables real-time execution of lighting control algorithms and HMI responsiveness within strict timing budgets.

Does this MCU support USB device functionality?

No, the XMC1202T028X0064AAXUMA1 does not include a USB transceiver or USB controller. It relies on USIC modules for UART, SPI, I²C, and I²S communication. For USB connectivity, external bridge ICs (e.g., CP2102 or FT232RL) must be used, or a higher-tier XMC4000 series MCU selected.

Can the VADC perform simultaneous sampling across multiple channels?

No, the VADC does not support true simultaneous sampling. It uses a hardware sequencer to scan up to 16 channels in programmable order with configurable sample times per channel. While sequential conversion occurs rapidly (≤1 µs per channel), inter-channel skew remains due to multiplexed input architecture.

Is there a factory-programmed bootloader in this device?

Yes, the device contains 8 KB of ROM containing a factory-programmed bootloader supporting UART-based firmware updates. This bootloader is accessible via P0.10 (RXD) and P0.11 (TXD) pins and supports flash programming without external debugger, enabling field firmware upgrades in deployed lighting systems.
