XMC4800-F100F1024AA
Arm Cortex-M4F MCU with on-chip EtherCAT, 144 MHz, 1 MB flash and 200 KB RAM for industrial drives and digital power.
Arm Cortex-M4F microcontroller with integrated EtherCAT slave controller, 1 MB flash and 200 KB RAM, targeting industrial automation, servo drives and digital power.
FAE Professional Review
The XMC4800 is our most frequently specified EtherCAT microcontroller. The integrated slave controller removes the need for an external ESC, and the 144 MHz Cortex-M4F leaves ample headroom for motor-control loops alongside the fieldbus stack. For designs that need precision current feedback, pair it with a TLE4972 sensor and the on-board delta-sigma ADC.

Frequently Asked Questions
What projects is the XMC4800-F100F1024AA best suited to?
It excels in industrial servo drives, EtherCAT fieldbus nodes and digital power converters, where 144 MHz of Cortex-M4F throughput plus an on-chip EtherCAT slave controller remove the need for an external ESC.
If your design is automotive or needs ISO 26262 lockstep, an AURIX part is a better match.
How do I get started with firmware and toolchain setup?
Infineon's DAVE environment and the XMC Flasher support this device, with motor-control and EtherCAT libraries available. Start from a reference project to validate the fieldbus stack before customizing.
Our FAE team can point you to the right starter project and toolchain setup.
What should I watch out for during board design?
Keep the 100-pin LQFP decoupling tight, follow the recommended analog supply filtering for the delta-sigma ADC, and give the EtherCAT magnetics proper isolation clearance.
The 1 MB flash and 200 KB RAM leave room for both the stack and control loops, so plan power and ground before layout sign-off.
How does it compare with the AURIX TC277TP?
The XMC4800 is an industrial Arm Cortex-M4F MCU with integrated EtherCAT, while the SAK-TC277TP-64F200N is an automotive TriCore device with lockstep safety and CAN FD. XMC wins on fieldbus integration and entry cost; AURIX wins on functional safety.
Choose based on whether automotive qualification is required.
What do the flash and RAM figures mean in practice?
1 MB flash holds the application, EtherCAT stack and motor-control code with room for updates, and 200 KB RAM covers dual control loops plus communication buffers. Typical drive firmware uses 40-60% of this budget.
Plan headroom for future features before freezing the BOM.
Is the part genuine, in stock, and what documents ship with it?
BeiLuo supplies factory-traceable XMC4800 parts with an import declaration, certificate of origin and RoHS file on every order. Stock is normally available and the datasheet downloads from this page.
