Lattice Semiconductor Corp. has announced the availability of the LatticeECP3 FPGA-enabled Sercos III solution. The product provides a low-cost and flexible design alternative for real-time industrial networking applications.

Sercos is a digital bus that interconnects motion controls, drives, I/O, sensors and actuators for numerically controlled machines and systems. It is designed for high-speed serial communication of standardized closed-loop real-time data over industrial Ethernet. The Sercos III real-time Ethernet evaluation kit consists of two boards (FPGA module and base board) and an optional expansion module. It is used for test implementations and performance measurements of Sercos III slave devices based on the SERCON100S slave IP core in combination with the LatticeMico32 soft microprocessor and other optional system functions.

Aside from the LatticeECP3-35, the FPGA module also consists of an 8MB Flash and 8MB DRAM. Its compact dimensions, wide bus and I/O interface allow it to be integrated as is into Sercos III slave devices.

The base board has 16DI and 16DO that have status LEDs, an RS232 interface, various switches and standardized bi-color Sercos III diagnostic LED. The board is supplied with 24VDC or 5VDC. A socket for expansion module allows the addition of more functions or interfaces such as analog I/O.

The LatticeECP3 FPGA family is suited for deployment in high-volume, cost- and power-sensitive industrial applications. It can also be used for video camera and display, wireline communications and wireless infrastructure.

The FPGA module is supported by the Automata Sercos III slave communication stack and test tools, such as a master simulator for Windows XP. A sample implementation of the Sercos III I/O profile (FSP-I/O) is available.

The Sercos III real-time Ethernet evaluation kit with the Lattice FPGA module can be purchased from Automata GmbH & Co. KG.
