Key Features
- 3-port EtherCAT slave controller compliant with IEC 61158, enabling daisy-chain or star industrial Ethernet topologies at 100 Mbps
- Integrated 32-bit MCU with 256 KB on-chip memory eliminates external processor for simple EtherCAT slave applications, reducing BOM and board area
- Multi-protocol host bus supporting 16-bit parallel, SPI, QSPI, and USB interfaces for flexible integration with diverse host processor families
Applications
The LAN9255-V/ZMX018 is purpose-built for industrial automation EtherCAT slave nodes such as servo drives, I/O modules, and motion controllers that require deterministic, sub-microsecond cycle synchronization across a 100 Mbps Ethernet network. Its integrated MCU and 256 KB memory allow standalone slave operation, making it ideal for compact fieldbus interface cards and distributed control panels in robotics, CNC machinery, and factory automation.

Frequently Asked Questions
How many EtherCAT ports does the LAN9255-V/ZMX018 support and what topology does that enable?
The LAN9255 integrates 3 EtherCAT ports running at 100 Mbps, which supports both daisy-chain line and star network topologies. In a daisy-chain configuration, each slave passes the frame to the next node, allowing up to 65,535 slave nodes on a single EtherCAT segment with sub-microsecond jitter across the entire network.
What host-side interfaces can a microcontroller use to communicate with the LAN9255-V/ZMX018?
Designers can connect a host processor to the LAN9255 via a 16-bit parallel bus, SPI, QSPI, or USB. The 16-bit bus supports data transfer rates up to 12.5 MBps, while the QSPI interface runs at up to 25 MHz and suits lower-pin-count embedded processors. This flexibility lets the device pair with diverse host MCUs from multiple silicon vendors.
For a servo drive design, why would LAN9255-V/ZMX018 be preferred over a discrete Ethernet PHY plus external CPU?
The LAN9255 integrates the EtherCAT slave controller, a 32-bit MCU, 256 KB on-chip memory, and 3 Ethernet MACs in a single 128-pin TQFP package, eliminating at least 3 separate ICs. This integration reduces PCB area by approximately 40%, cuts BOM cost, and shortens firmware development time because the EtherCAT stack can run on the internal MCU without a separate RTOS processor.
What package does LAN9255-V/ZMX018 come in and what are its key electrical requirements?
The device is housed in a 128-pin TQFP package with a 0.4 mm lead pitch, operating from a 3.3 V core supply. The maximum clock frequency is 25 MHz for the host bus interface, and the chip supports boundary scan (JTAG) for board-level testing. The ZMX018 variant designates the specific packaging and tape-and-reel configuration for automated assembly.
