ET1825, ET1826, ET1827 | EtherCAT IP core for Lattice® FPGAs
ET1825, ET1826, ET1827 | EtherCAT IP core for Lattice® FPGAs
The EtherCAT IP core enables the EtherCAT communication function and application-specific functions to be implemented on an FPGA (field programmable gate array, an integrated circuit containing programmable logical components). The EtherCAT functionality is freely configurable. The IP core can be combined with your own FPGA designs or integrated into system-on-chips (SoCs) with soft-core processors or hard processor systems via AMBA® AXI™ interfaces. The physical interfaces and internal functions, such as the number of FMMUs and SYNC managers and the size of the DPRAM, are configurable. The process data interface (PDI) and the distributed clocks are also configurable. The functions are compatible with the EtherCAT specification and the EtherCAT ASIC ET1100.
The ET1826 quantity-based node-locked license offers small-batch manufacturers and development service providers in particular the option to enter the world of EtherCAT development with a low initial investment. The ET1826 one-time kick-off charge and the license fees for 1,000 ET1826-1000 devices are required for the development of an EtherCAT device. The license fees for 1000 devices must each be paid in advance.
Development service providers only require the ET1826 basic license; the ET1826-0030 system integrator OEM license is required for each customer implementation. The quantity-based license (ET1826-1000) is purchased by the end customer.
The license includes one year of maintenance and updates to ensure that you always have access to the latest developments and improvements.
The EtherCAT IP core can be tested once, with the test period lasting three months, free of charge. The evaluation license has the following pre-requisites: free membership of the EtherCAT Technology Group with an existing Vendor ID.
