FAQ

What is the maximum operating frequency of the XMC4400F64K512BAXQMA1?

The device operates at up to 125 MHz CPU frequency, achieved via its integrated Phase-Locked Loop (PLL) with programmable multiplication factor. This frequency is guaranteed across the full -40°C to +125°C ambient temperature range and 1.3 V core supply, enabling real-time execution of complex control algorithms without throttling.

Does the XMC4400F64K512BAXQMA1 support functional safety standards like IEC 61508?

Yes - the device includes safety features such as lockstep-capable watchdog timers (WDT), memory protection unit (MPU), ECC on Flash and SRAM, and hardware CRC engine (FCE). It is qualified for SIL2 applications per IEC 61508 and supports diagnostic firmware libraries provided by Infineon's SafeTI™-compliant XMC4000 Safety Package.

Can the USB interface operate in host mode without external components?

Yes - the integrated USB 2.0 Full-Speed OTG controller includes a physical layer (PHY), eliminating the need for an external transceiver. It supports both device and host modes, with dedicated DMA channels for zero-copy data transfers, enabling direct connection to USB HID devices or flash storage in field-service tools.

How many CAN nodes does the XMC4400F64K512BAXQMA1 support?

The device integrates two independent CAN 2.0B controllers (CAN0 and CAN1), each supporting up to 64 message objects and bit rates up to 1 Mbit/s. Both controllers operate concurrently and can be configured for different protocols (e.g., CANopen on CAN0, J1939 on CAN1) without shared resource contention.
