This contribution presents the design and implementation of a SNTP client module suitable for IEC 61850 environments fully done in hardware. The module is able to provide synchronization and accurate time reference within a microsecond with respect to a SNTP server, in a extremely compact, cost-effective and low power device completely implemented in a low grade FPGA chip. Therefore it can be an ideal replacement to expensive computer-based solutions or dedicated GPS receivers in a wide range of industrial applications. This SNTP client is part of a common technological platform for implementing Remote Terminal Units (RTUs) under IEC 61850.
