Infineon Technologies XMC1202T028X0032AAXUMA1

Overview

XMC1202T028X0032AAXUMA1 from Infineon Technologies is an ARM® Cortex™-M0 32-bit microcontroller with 32 KB on-chip Flash, 16 KB SRAM, and integrated analog peripherals including a 12-bit VADC (16-channel), 2x CCU4 timers, and USIC serial interfaces. It targets LED lighting control and HMI systems requiring real-time PWM generation, analog sensing, and compact industrial firmware execution.

For engineers reviewing the XMC1202T028X0032AAXUMA1 datasheet, XMC1202T028X0032AAXUMA1 pinout, XMC1202T028X0032AAXUMA1 application, or XMC1202T028X0032AAXUMA1 equivalent, key selection criteria include Flash/SRAM size, VADC resolution and channel count, CCU4 timer precision for LED dimming, USIC interface flexibility (SPI/I²C/UART), and TSSOP-28 package compatibility with space-constrained PCB layouts.

Technical Context

The device implements a single-cycle ARM Cortex-M0 core operating up to 48 MHz, supported by a dedicated AHB-Lite bus for CPU-to-Flash/SRAM access and APB bus for peripheral control. Its analog subsystem integrates a voltage-controlled oscillator (VCO)-based DCO for clock generation, a temperature sensor, and two independent analog comparators with out-of-range detection.

Peripheral timing is managed via the CCU4 (Capture/Compare Unit) for high-resolution PWM and dead-time insertion, and the USIC (Universal Serial Interface Channel) supporting simultaneous SPI master/slave, I²C, and UART modes with configurable baud rates and FIFO buffering - critical for multi-sensor HMI communication and synchronized LED driver signaling.

FAQ

What is the maximum operating frequency of the XMC1202T028X0032AAXUMA1?

The device operates at a maximum CPU frequency of 48 MHz, derived from its internal DCO or external crystal oscillator. This speed is validated across the full industrial temperature range (–40°C to +105°C) and supports real-time execution of LED dimming algorithms and sensor fusion routines without jitter.

Does the XMC1202T028X0032AAXUMA1 support in-circuit debugging?

Yes - it features a 2-pin Serial Wire Debug (SWD) interface (SWDIO and SWCLK) compliant with ARM CoreSight standards. This enables full flash programming, breakpoint setting, and real-time variable inspection using standard tools like Segger J-Link or Infineon DAVE™ IDE without requiring additional debug headers.

Can the VADC perform simultaneous sampling on multiple channels?

No - the 12-bit VADC uses a single SAR converter with a hardware sequencer that scans up to 16 channels in programmable order. While it cannot sample all channels at the exact same instant, its 1.2 MSps conversion rate allows sub-microsecond inter-channel delays suitable for correlated measurements like LED current and heatsink voltage.

Is the TSSOP-28 package RoHS-compliant and halogen-free?

Yes - the XMC1202T028X0032AAXUMA1 uses a lead-free, RoHS-compliant TSSOP-28 package meeting JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) and IPC/JEDEC J-STD-075 halogen-free requirements, verified per Infineon's material declarations dated 2014 and later revisions.
