Infineon Technologies XMC1402F064X0128AAXUMA1

Overview

XMC1402F064X0128AAXUMA1 from Infineon Technologies is an ARM® Cortex®-M0 32-bit microcontroller optimized for industrial real-time control, featuring 128 KB Flash, 16 KB SRAM with parity, and a 48 MHz CPU clock. It integrates dual 12-bit ADCs (up to 1.1 MS/s), two CCU8 timer units for complementary PWM generation, and MultiCAN+ with two nodes and 32 message objects - deployed in motor drive inverters and digital power supplies.

For engineers reviewing the XMC1402F064X0128AAXUMA1 datasheet, XMC1402F064X0128AAXUMA1 pinout, XMC1402F064X0128AAXUMA1 application, or XMC1402F064X0128AAXUMA1 equivalent, key selection considerations include its 96 MHz CCU8 timer base, 1.8–5.5 V supply range, 48-pin LQFP package, and support for single-pin bootloader and secure SBSL.

Technical Context

The device implements a deterministic real-time architecture centered on dual CCU8 modules (each with four 16-bit channels) capable of generating synchronized, phase-shifted, and dead-time-controlled PWM signals for three-phase motor control and resonant LLC converters. Its analog subsystem includes two independent VADC kernels with 12-bit resolution, sample-and-hold stages, and 0–5.5 V input range - enabling direct sensing of high-side current shunts without external signal conditioning.

Communication is handled via two USIC modules (four total channels), configurable as UART, SPI (single/dual/quad), IIC, IIS, or LIN - with hardware-accelerated protocol handling and up to 12 Mb/s data rates. The integrated MultiCAN+ controller supports full-CAN and Basic-CAN modes at up to 1 MBaud, with dedicated message object RAM and hardware filtering for robust fieldbus integration.

FAQ

What debug interfaces does XMC1402F064X0128AAXUMA1 support?

The device supports ARM Serial Wire Debug (SWD) with four hardware breakpoints and two watchpoints, plus a single-pin debug interface for minimal PCB footprint. It does not support JTAG. SWD operates at up to 24 MHz and is compatible with standard CMSIS-DAP debug probes and Infineon's DASLink tools.

Does this MCU include hardware security features beyond SBSL?

Yes - it integrates a pseudo-random number generator (PRNG) compliant with NIST SP 800-90A, memory protection unit (MPU) with eight regions, and flash lock bits for read/write protection. Secure boot relies on factory-programmed SBSL; user firmware can implement additional layers using MPU and PRNG for key derivation.

Can the on-chip oscillators meet timing requirements for CAN communication?

The internal fast oscillator (FOSC) is rated at ±2% accuracy over temperature and voltage - insufficient for CAN bit timing at 1 MBaud. For full CAN compliance, an external 4–20 MHz crystal must be used with the on-chip PLL to generate a stable system clock; the datasheet specifies 8 MHz ±0.2% crystal for 1 MBaud operation.

How many independent PWM outputs can be generated simultaneously?

Using both CCU8 units (CCU80 and CCU81), the device supports up to eight independent PWM channels with full complementary pair control, dead-time insertion, and synchronization. Each CCU8 provides four 16-bit channels, and all eight can operate concurrently with independent period/duty-cycle registers and event-triggered updates.
