Infineon Technologies XMC1402F064X0064AAXUMA1

Overview

XMC1402F064X0064AAXUMA1 from Infineon Technologies is a 32-bit ARM Cortex-M0 microcontroller designed for real-time industrial control, featuring 64 KB Flash, 16 KB SRAM with parity, 48 MHz CPU frequency, dual 12-bit ADCs (up to 12 analog inputs, 1.1 MS/s), and integrated CCU4/CCU8 PWM timers for motor and power conversion. It operates across -40°C to 105°C and supports 1.8–5.5 V supply.

For engineers reviewing the XMC1402F064X0064AAXUMA1 datasheet, XMC1402F064X0064AAXUMA1 pinout, XMC1402F064X0064AAXUMA1 application, or XMC1402F064X0064AAXUMA1 equivalent, key selection criteria include on-chip analog frontend capability (ADC + ORC + ACMP), deterministic PWM timing (96 MHz CCU8), MultiCAN+ support (2 nodes, 32 MOs), and single-pin bootloader for field firmware updates.

Technical Context

This device implements a deterministic real-time control architecture optimized for digital power supplies and BLDC motor drives. Its dual CCU8 modules deliver synchronized complementary PWM outputs with dead-time insertion and fault protection, while the two USIC channels support concurrent UART, SPI, and I²C interfaces at up to 12 Mb/s.

The analog subsystem integrates two independent 12-bit ADCs with sample-and-hold, configurable gain, and 0–5.5 V input range-enabling direct sensing of high-side current shunts and bus voltages without external signal conditioning. The on-chip temperature sensor and 4 fast analog comparators further enable thermal monitoring and overvoltage/overcurrent trip functions.

FAQ

What is the maximum ADC sampling rate supported by XMC1402F064X0064AAXUMA1?

The device supports up to 1.1 million samples per second (1.1 MS/s) across its dual 12-bit ADCs, with two independent sample-and-hold stages enabling simultaneous sampling of current and voltage signals in motor control applications. This rate is achievable at full 12-bit resolution under specified operating conditions (VDDA = 5.5 V, TA ≤ 85°C).

Does XMC1402F064X0064AAXUMA1 support hardware-based dead-time insertion for PWM outputs?

Yes, both CCU8 modules provide fully configurable hardware dead-time insertion (adjustable from 1 to 65535 clock cycles) with automatic fault-triggered blanking and emergency shutdown. This feature eliminates software timing jitter and ensures safe switching of high-side/low-side MOSFETs in half-bridge configurations.

Can the XMC1402F064X0064AAXUMA1 operate without an external crystal?

Yes-it includes internal slow (100 kHz) and fast (48 MHz) RC oscillators, allowing full operation without external crystals. However, for motor control and power conversion applications requiring precise timing (e.g., current loop synchronization), Infineon recommends using the 4–20 MHz external crystal connected to OSC_IN/OSC_OUT for ±50 ppm stability.

Is the single-pin bootloader compatible with standard UART interfaces?

Yes-the bootloader uses UART0 (P0.10/Rx, P0.11/Tx) and enters upon reset with BOOT0 = low and BOOT1 = high. It supports standard 8-N-1 framing at baud rates from 9600 to 115200 bps and requires no external programmer, enabling firmware updates directly from host MCUs or PC-based tools via RS-232 or USB-to-UART bridges.
