Infineon Technologies XMC1402Q040X0064AAXUMA1

Overview

XMC1402Q040X0064AAXUMA1 from Infineon Technologies is an ARM® Cortex®-M0 32-bit microcontroller designed for real-time industrial control, featuring 48 MHz CPU frequency, 64 KB Flash with ECC, 16 KB SRAM with parity, and dual 12-bit VADC cores supporting up to 12 analog inputs. It integrates CCU4/CCU8 timers for motor PWM, POSIF for encoder interfacing, and USIC modules configurable as UART/SPI/IIC/IIS/LIN - deployed in digital power supplies and BLDC motor drives.

For engineers reviewing the XMC1402Q040X0064AAXUMA1 datasheet, XMC1402Q040X0064AAXUMA1 pinout, XMC1402Q040X0064AAXUMA1 application, or XMC1402Q040X0064AAXUMA1 equivalent, key selection criteria include its 48-pin VQFN package, -40°C to 105°C operating range, 1.8–5.5 V supply tolerance, and integrated analog comparators + out-of-range detection for closed-loop protection circuits.

Technical Context

This device implements a deterministic real-time control architecture with 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 power conversion topologies.

The USIC peripheral supports hardware-accelerated serial protocols including quad-SPI (up to 4 × 12 Mb/s) and LIN (20 kb/s), while MultiCAN+ provides two CAN nodes with 32 message objects at up to 1 MBaud - all synchronized via the AHB-Lite bus and managed by NVIC with 64 interrupt vectors for low-latency response.

FAQ

Does XMC1402Q040X0064AAXUMA1 include MultiCAN+ functionality?

No. This specific variant (Q040 package, 64 KB Flash) does not include MultiCAN+ peripherals, as confirmed in Table 1 of the XMC1400 datasheet. Only XMC1403 and XMC1404 derivatives support MultiCAN+ with two CAN nodes and 32 message objects. For CAN-enabled designs, XMC1404F048X0200AAXUMA1 is the minimum compatible option.

What debug interfaces are supported on this MCU?

XMC1402Q040X0064AAXUMA1 supports ARM Serial Wire Debug (SWD) with four hardware breakpoints and two watchpoints. It does not support JTAG. The single-pin bootloader uses UART mode via dedicated pin P0.10, enabling firmware updates without debug probe dependency - ideal for field maintenance.

Is the 64 KB Flash memory protected against corruption during power fluctuations?

Yes. The Flash includes Error Correction Code (ECC) circuitry that detects and corrects single-bit errors and detects double-bit errors in real time. Combined with brown-out detection and programmable reset thresholds, this ensures firmware integrity during voltage sags common in industrial power environments.

Can the VQFN-48 package be hand-soldered reliably?

The 7 mm × 7 mm VQFN-48 with 0.5 mm pitch requires reflow soldering per IPC-J-STD-020 guidelines. Hand-soldering is not recommended due to thermal pad accessibility and fine-pitch alignment risk. Infineon specifies a maximum peak reflow temperature of 260°C for 30 seconds; stencil design must ensure ≥80% solder paste coverage on the exposed thermal pad.
