Infineon Technologies XMC1302T038X0064AAXUMA1

Overview

XMC1302T038X0064AAXUMA1 from Infineon Technologies is a 32-bit ARM® Cortex®-M0 microcontroller with 64 KB flash, 16 KB SRAM, and integrated peripherals including VADC (12-bit, 16-channel), CCU4/CCU8 timer units, and USIC serial interfaces. It operates at up to 48 MHz, supports industrial motor control and digital power conversion, and features hardware-based PWM generation with dead-time insertion.

For engineers reviewing the XMC1302T038X0064AAXUMA1 datasheet, XMC1302T038X0064AAXUMA1 pinout, XMC1302T038X0064AAXUMA1 application, or XMC1302T038X0064AAXUMA1 equivalent, key selection criteria include flash/SRAM size, real-time peripheral integration (e.g., CCU8 for high-resolution PWM), analog subsystem capability (VADC + ACMP + ORC), and TSSOP-38 package compatibility with industrial PCB layouts.

Technical Context

The device implements an ARM Cortex-M0 core with Thumb/Thumb2 instruction set support, single-cycle 32-bit hardware multiplier, and SysTick timer for RTOS integration. Its peripheral subsystem includes two independent CCU4 modules (each with four 16-bit timers) and one CCU8 module (eight 16-bit timers with center-aligned PWM and dead-time control).

The analog system integrates a 12-bit VADC with 16 input channels, two analog comparators (ACMP), and an out-of-range comparator (ORC) for fast overvoltage/undervoltage detection in power stage monitoring - all synchronized to PWM events via ERU event routing.

FAQ

What debug interface does XMC1302T038X0064AAXUMA1 support?

The device uses Serial Wire Debug (SWD) with a 2-pin interface (SWDIO and SWCLK), supporting full JTAG-style debugging, flash programming, and real-time memory access via standard ARM-compliant tools including DAVE™ Debugger and SEGGER J-Link. No external debug adapter is required beyond a SWD header.

Does XMC1302T038X0064AAXUMA1 include hardware CRC calculation?

Yes - it integrates a dedicated CRC module compliant with CRC-32 (IEEE 802.3) and CRC-16 (CCITT) standards, operating independently of the CPU with DMA support. This enables fast checksum validation of firmware images and communication payloads without consuming CPU cycles.

Can the VADC perform simultaneous sampling across multiple channels?

Yes - the VADC supports hardware-synchronized sampling of up to four channels using group conversions triggered by CCU8 PWM events. This allows precise time-aligned acquisition of motor phase currents and DC-link voltage for vector control algorithms.

What is the maximum operating temperature range for this part?

XMC1302T038X0064AAXUMA1 is qualified for industrial operation from −40°C to +125°C (junction temperature). The TSSOP-38 package achieves this rating with appropriate PCB copper area (≥200 mm² thermal pad exposure) and airflow ≥0.5 m/s in enclosure design.
