Product details
Overview
XMC1402T038X0128AAXUMA1 from Infineon Technologies is an ARM® Cortex®-M0 32-bit microcontroller designed for real-time industrial control, featuring 48 MHz CPU frequency, 128 KB Flash with ECC, 16 KB SRAM with parity, and dual 12-bit VADC cores supporting up to 12 analog inputs. It integrates CCU8 and CCU4 timers for motor PWM, POSIF for encoder interfacing, and USIC modules configurable as UART/SPI/IIC/IIS/LIN - deployed in digital power supplies and brushless DC motor drives.
For engineers reviewing the XMC1402T038X0128AAXUMA1 datasheet, XMC1402T038X0128AAXUMA1 pinout, XMC1402T038X0128AAXUMA1 application, or XMC1402T038X0128AAXUMA1 equivalent, key selection criteria include its TSSOP-38 package, -40°C to +105°C operating range, 1.8–5.5 V supply tolerance, integrated LEDTS for HMI, and MultiCAN+ support for distributed industrial networks.
Technical Context
The device implements a deterministic real-time architecture centered on two independent CCU8 timer units (96 MHz), each supporting complementary PWM outputs with dead-time insertion and fault protection - essential for three-phase inverter gate driving. Its dual VADC subsystem includes sample-and-hold stages and programmable gain amplifiers, enabling simultaneous sampling of current and voltage feedback in servo loops.
Communication is handled by two USIC modules (4 channels total), each independently configurable per protocol: SPI supports quad-SPI mode at up to 4 × 12 Mb/s for fast configuration of external power ICs; IIC runs at 400 kb/s for sensor bus integration; LIN operates at 20 kb/s for low-cost actuator control. The embedded MultiCAN+ controller supports full-CAN with 32 message objects and 1 MBaud data rate.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M0 @ 48 MHz, 0.84 DMIPS/MHz - delivers deterministic interrupt latency ≤12 cycles for time-critical motor commutation. |
| Flash Memory | 128 KB with ECC - ensures firmware integrity in EMI-heavy industrial environments; supports over-the-air updates with rollback protection. |
| SRAM | 16 KB with parity - detects single-bit memory errors in real-time control variables and stack operations. |
| Analog Inputs | 12-channel, 12-bit VADC with 2-stage sample-and-hold - enables synchronized current/voltage acquisition for field-oriented control (FOC). |
| PWM Timers | 2× CCU8 (96 MHz) + 2× CCU4 (96 MHz) - provides 8 independent PWM channels with center-aligned mode, dead-time control, and emergency shutdown inputs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar industrial microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XMC1402Q048X0128AAXUMA1 | VQFN-48 package (7×7 mm²), 48 GPIOs vs. 26 in TSSOP-38; adds second POSIF unit and LEDTS channel. | Better suited for space-constrained but I/O-rich designs like multi-axis motion controllers. | Select when needing >24 GPIOs, dual encoder interfaces, or thermal performance beyond TSSOP limits. |
| XMC1402F048X0128AAXUMA1 | LQFP-48 package (7×7 mm²), same peripheral set as Q048 but with exposed thermal pad and higher moisture sensitivity level (MSL3). | Preferred for reflow-compatible high-volume manufacturing with standard SMT lines. | Choose for automated assembly compatibility and improved thermal dissipation in sealed enclosures. |
Compared with XMC1402Q048 and XMC1402F048, the TSSOP-38 variant offers lowest PCB footprint and easiest hand-soldering for prototyping and low-volume motor control modules - while retaining identical core peripherals, Flash/SRAM, and industrial temperature rating.

FAQ
Does XMC1402T038X0128AAXUMA1 support CAN FD?
No - it integrates MultiCAN+, a legacy CAN 2.0B controller supporting up to 1 MBaud with 32 message objects and hardware filtering, but lacks CAN FD's variable bit rate and extended data length. For CAN FD, consider XMC4000 series devices.
What debug interfaces does this MCU provide?
It supports ARM Serial Wire Debug (SWD) via dedicated SWDIO and SWCLK pins, enabling full JTAG-equivalent functionality including breakpoints, watchpoints, and real-time memory access - no UART bootloader required for firmware update or debug.
Is the 128 KB Flash field-programmable and wear-levelled?
Yes - the Flash supports in-system programming via SWD or bootloader, with ECC protection and sector erase (2 KB minimum). Wear leveling must be implemented in application firmware; no hardware wear-leveling engine is present.
Can the VADC measure signals above 5.5 V?
No - the absolute maximum analog input voltage is 5.5 V, and the specified input range is 0–5.5 V. External resistive dividers or signal conditioners are required for higher-voltage measurements such as 400 V DC-link monitoring.
