Product Specifications

Technical details and manufacturing context for EtherCAT Protocol Processor

Definition

The EtherCAT Protocol Processor is a dedicated processing unit embedded within an EtherCAT Master Chip. Its primary function is to execute the low-level EtherCAT protocol stack in hardware, managing frame assembly, disassembly, cyclic data exchange (Process Data), acyclic mailbox communication, and ensuring deterministic, real-time communication with EtherCAT slave devices on the network. It offloads these time-critical tasks from the main host CPU. The processor operates by generating and parsing EtherCAT telegrams according to the IEC 61158 standard. It manages the master's data link layer (Layer 2), inserting and extracting slave I/O data into/from the circulating Ethernet frame as it passes through the processor's logic. It handles distributed clock synchronization, error detection, and state machine management for the network slaves, enabling precise, jitter-free control cycles. This component is part of the Computer, Electronic and Optical Product Manufacturing industry and is classified as a component at the part level. It is typically fabricated from silicon semiconductor material. Directory reference ranges for key parameters include a protocol processing rate of 100–1000 Mbit/s (IEC 61158), frame processing latency of ≤1 μs, process data RAM of 8–64 KB, support for 32–256 slaves, operating voltage of 1.8–3.3 V DC, power consumption of 0.5–2.5 W, operating temperature of -40–85 °C (IEC 60068-2-14), package types from QFP-100 to BGA-256 (JEDEC MS-026), and weight of 2–10 g. These values are reference ranges and must be verified for the specific model and application. The processor is designed for industrial environments, but compliance with standards must be confirmed with the legal manufacturer or supplier.

Working Principle

The EtherCAT Protocol Processor generates and parses EtherCAT telegrams per IEC 61158. It manages the master's data link layer, inserting and extracting slave I/O data into/from the circulating Ethernet frame. It handles distributed clock synchronization, error detection, and state machine management for network slaves, enabling deterministic, jitter-free control cycles.
