Product details
Overview
XMC1302T038X0032AAXUMA1 from Infineon Technologies is an ARM® Cortex®-M0 32-bit microcontroller designed for real-time industrial control, featuring 32 KB on-chip Flash, 16 KB SRAM, and integrated peripherals including VADC (12-bit, 16-channel), CCU4/CCU8 timers, USIC serial interfaces, and hardware-based ERU event routing. It targets motor control, digital power conversion, and LED lighting systems with deterministic timing and low-latency interrupt response.
For engineers reviewing the XMC1302T038X0032AAXUMA1 datasheet, XMC1302T038X0032AAXUMA1 pinout, XMC1302T038X0032AAXUMA1 application, or XMC1302T038X0032AAXUMA1 equivalent, key selection criteria include Flash/SRAM size, VADC resolution and channel count, CCU8 timer precision for PWM generation, USIC interface flexibility (SPI/I²C/I²S), and thermal performance in TSSOP-38 packaging.
Technical Context
The XMC1302T038X0032AAXUMA1 implements a single-core ARM Cortex-M0 CPU running at up to 48 MHz, with tightly coupled AHB-Lite and APB buses enabling deterministic peripheral access. Its VADC supports simultaneous sampling across 16 channels with configurable conversion sequences and hardware post-processing.
Real-time control is enhanced by dual CCU8 modules offering 16-bit resolution, dead-time insertion, and synchronized PWM outputs, while the ERU enables zero-CPU-latency event chaining between analog comparators, timers, and GPIOs - critical for overcurrent protection and fast-loop feedback in motor drives.

FAQ
What is the maximum operating frequency and supported voltage range?
The XMC1302T038X0032AAXUMA1 operates at up to 48 MHz with a core supply (VDD) range of 1.71 V to 5.5 V and analog supply (VDDP) of 3.0 V to 5.5 V. It maintains full peripheral functionality across this range, enabling direct connection to 3.3 V or 5 V systems without level-shifting.
Does it support hardware-based PWM dead-time insertion?
Yes - both CCU8 modules provide configurable hardware dead-time insertion (1–255 ns resolution) with automatic synchronization across multiple PWM outputs. This eliminates software timing errors and ensures reliable gate driver control in half-bridge and three-phase inverter topologies.
Is there built-in debug capability without additional pins?
Yes - the device integrates Serial Wire Debug (SW-DP) accessible via a single bidirectional pin (SWDIO) and SWCLK, requiring only two PCB traces. Full JTAG/SWD debugging, flash programming, and real-time variable inspection are supported without dedicated debug headers.
How is analog measurement accuracy maintained under varying temperature?
The VADC includes internal calibration registers updated at power-on and supports periodic self-calibration. Combined with the on-die temperature sensor (±2°C accuracy), firmware can apply gain/offset correction tables - achieving <±1 LSB INL over -40°C to 125°C in typical motor control layouts.
