Infineon Technologies XMC1302T038X0016AAXUMA1

Overview

XMC1302T038X0016AAXUMA1 from Infineon Technologies is a 32-bit ARM® Cortex®-M0 microcontroller in the XMC1000 family, designed for real-time industrial control. It integrates 16 kB SRAM, 200.5 kB on-chip Flash (including 0.5 kB read-only sector 0), and features a 48 MHz max CPU frequency, VADC with 12-bit resolution, and CCU4/CCU8 timer units for motor control timing.

Technical Context

The device implements a single-cycle 32-bit hardware multiplier and SysTick timer for RTOS support, with AHB-Lite and APB bus architecture enabling deterministic peripheral access. Its analog subsystem includes a 12-bit VADC with up to 16 channels, two analog comparators (ACMP), and an out-of-range comparator (ORC) for overvoltage/undervoltage monitoring.

Real-time control capability is enhanced by dedicated hardware peripherals: CCU40 provides four 16-bit capture/compare units with dead-time insertion and shadow transfer; CCU80 offers eight 16-bit channels optimized for three-phase motor control with center-aligned PWM and fault protection inputs.

FAQ

What is the maximum operating frequency of the XMC1302T038X0016AAXUMA1?

The device operates at a maximum CPU frequency of 48 MHz, derived from its internal 48 MHz oscillator or external crystal input. This frequency is fully supported across the specified industrial temperature range (–40 °C to +105 °C) and supply voltage (1.3 V core, 3.3 V I/O), with all peripherals functional at rated speed.

Does this MCU support hardware-based PWM dead-time insertion?

Yes - the CCU40 peripheral includes configurable dead-time generators for complementary PWM outputs. Each channel supports independent dead-time values (programmable in 1–128 ns steps), automatic fault-triggered blanking, and synchronous update via shadow registers to prevent glitches during runtime parameter changes.

Can the VADC perform simultaneous sampling across multiple channels?

No - the VADC has a single SAR converter with multiplexed inputs. While it supports sequencer-based scanning of up to 16 channels per trigger, true simultaneous sampling requires external analog front-end circuitry. However, the shortest conversion time is 1.2 µs per channel at 12-bit resolution under optimal conditions.

Is the on-chip temperature sensor calibrated at factory?

Yes - the integrated temperature sensor is factory-calibrated with two-point characterization (at 25 °C and 100 °C), stored in dedicated flash locations. Software can apply linear interpolation using these coefficients to achieve ±2.5 °C accuracy across the full operating range without external calibration.
