Infineon Technologies XMC1402Q048X0032AAXUMA1

Overview

XMC1402Q048X0032AAXUMA1 from Infineon Technologies is an ARM® Cortex®-M0 32-bit microcontroller with 48 MHz CPU frequency, 32 KB Flash, 16 KB SRAM (with parity), and industrial-grade operating temperature range of −40 °C to 105 °C. It integrates dual 12-bit VADCs (up to 12 analog inputs, 1.1 MS/s), two CCU8 timer units for high-resolution PWM generation, and two USIC modules supporting UART/SPI/IIC/IIS up to 12 Mb/s - deployed in motor control and digital power conversion systems.

For engineers reviewing the XMC1402Q048X0032AAXUMA1 datasheet, XMC1402Q048X0032AAXUMA1 pinout, XMC1402Q048X0032AAXUMA1 application, or XMC1402Q048X0032AAXUMA1 equivalent, key selection criteria include its 96 MHz CCU8 timer clock capability, 1.8–5.5 V supply flexibility, integrated LEDTS for HMI, MultiCAN+ support (2 nodes, 32 message objects), and TSSOP-38 package compatibility with space-constrained industrial PCB layouts.

Technical Context

The XMC1402Q048X0032AAXUMA1 implements a deterministic real-time control architecture centered on dual CCU8 units-each delivering 16-bit resolution, 96 MHz base clock, and hardware-complementary PWM outputs for three-phase motor drives. Its VADC subsystem features two independent kernels with sample-and-hold stages, enabling synchronized sampling across up to 12 analog channels at 1.1 MS/s with programmable gain.

Communication is handled by two USIC modules, each configurable as UART, SPI (single/dual/quad), IIC, IIS, or LIN; one supports full-duplex quad-SPI at up to 4 × 12 Mb/s. The device includes a dedicated BCCU for LED brightness/color control and POSIF for quadrature encoder interface-both tightly coupled to CCU8 for closed-loop timing-critical feedback.

FAQ

Does XMC1402Q048X0032AAXUMA1 support secure boot?

Yes - it includes an optional Secure Bootstrap Loader (SBSL) that validates signed firmware images before execution. SBSL resides in ROM and enforces cryptographic signature verification using ECDSA over NIST P-256, preventing unauthorized code execution during startup.

What is the maximum ADC sampling rate with hardware trigger from CCU8?

The VADC supports hardware-triggered conversions at up to 1.1 MS/s per kernel. When triggered by CCU8 event signals (e.g., PWM center-aligned zero-crossing), conversion start latency is fixed at 3 CPU cycles - enabling sub-microsecond deterministic sampling aligned to motor phase transitions.

Can the USIC modules operate simultaneously as UART and SPI?

Yes - each USIC module is independently configurable. For example, USIC0 can run as full-duplex UART at 12 Mb/s while USIC1 operates as quad-SPI at 4 × 12 Mb/s. Both share no internal resource conflicts and maintain separate FIFOs and clock domains.

Is the TSSOP-38 package RoHS and REACH compliant?

Yes - XMC1402Q048X0032AAXUMA1 meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free matte tin terminal finish and halogen-free molding compound, certified per Infineon's Material Declaration Sheet 2025-07-17 rev. V1.7.
