Infineon Technologies XMC1402T038X0200AAXUMA1

Overview

XMC1402T038X0200AAXUMA1 from Infineon Technologies is a 32-bit ARM Cortex-M0 microcontroller designed for real-time industrial control, featuring 200 kB Flash, 16 kB SRAM with parity, 48 MHz CPU frequency, -40 to 105°C operating temperature, and TSSOP-38 package. It integrates dual 12-bit ADCs (up to 1.1 MS/s), two CCU8 timer units for complementary PWM generation, one POSIF for motor position sensing, and three LEDTS modules for capacitive touch and LED driving - deployed in brushless DC motor drives and digital power supplies.

For engineers reviewing the XMC1402T038X0200AAXUMA1 datasheet, XMC1402T038X0200AAXUMA1 pinout, XMC1402T038X0200AAXUMA1 application, or XMC1402T038X0200AAXUMA1 equivalent, key selection criteria include its 96 MHz CCU8 timer clocking, 1.8–5.5 V supply range, integrated analog comparators and out-of-range detectors, and support for single-pin bootloader and SW-DP debug.

Technical Context

The device implements an ARM Cortex-M0 core delivering 0.84 DMIPS/MHz at 48 MHz, paired with a dedicated MATH coprocessor supporting CORDIC-based trigonometric calculations and 32-bit division. Its interrupt subsystem includes NVIC with 64 nodes and two ERU modules enabling hardware event routing without CPU intervention.

Analog subsystem features two independent VADC kernels with 12-bit resolution, 2-stage sample-and-hold, and programmable gain amplifiers; each supports up to 12 analog inputs across a 0–5.5 V range. The CCU8 unit provides four 16-bit channels per module with dead-time insertion, shadow register updates, and fault protection - essential for high-reliability inverter gate drive timing.

FAQ

What is the maximum ADC sampling rate supported by XMC1402T038X0200AAXUMA1?

The device supports up to 1.1 million samples per second (1.1 MS/s) across its two 12-bit VADC kernels. Each kernel can handle up to 12 analog inputs with 2-stage sample-and-hold, and the conversion result is accessible via DMA or interrupt-driven reads. This rate enables accurate capture of fast transients in motor phase currents and DC-link voltages without external oversampling.

Does XMC1402T038X0200AAXUMA1 support hardware-based dead-time insertion for PWM outputs?

Yes - both CCU8 modules include dedicated dead-time generators with programmable delay (down to 1 ns resolution) and automatic update on compare match. These operate independently of CPU intervention and synchronize with complementary channel pairs to prevent shoot-through in half-bridge configurations used in inverters and motor drivers.

Can the LEDTS peripheral be used simultaneously for capacitive touch sensing and LED driving?

Yes - the three LEDTS modules support concurrent operation: one can scan up to 24 capacitive touch pads while another drives up to 48 LEDs in constant-current mode, and the third handles mixed-mode operation. Time-division multiplexing is managed in hardware, eliminating software overhead and ensuring consistent response latency for both functions.

Is the XMC1402T038X0200AAXUMA1 qualified for automotive applications?

No - it is rated for industrial temperature range (-40 to +105°C) and qualified per AEC-Q100 Grade 2 only in select variants; this specific part number carries industrial qualification and lacks automotive-specific documentation such as PPAP or FMEDA reports. For automotive use, Infineon recommends the A-Step qualified XMC1402F048F0200AAXUMA1 with full AEC-Q100 Grade 2 compliance.
