ST7580 power line communication system-on-chip design guide
By Riccardo Fiorelli, Mauro Colombo
Introduction
The ST7580 reference design has been realized as a useful tool that exploits the
performance capability of the ST7580 power line networking system-on-chip.
With this reference design, it is possible to evaluate, directly on the power line, the
transmitting and receiving performance of a power line communication node based on the
ST7580 device.
The line coupling interface is designed to allow the ST7580 device to transmit and receive
on the AC mains line using the available FSK and PSK modes within the European
CENELEC EN50065-1 standard A band, specified for automatic meter reading (AMR)
applications [5]. The circuit has been designed to be easily adapted to different frequency
bands and application environments with very few modifications.
An STM32 microcontroller has been included in the reference design to make it more
flexible and suitable for use as a standalone smart PLC node.

Note:
As can be seen from the board image, special effort has been made to make the reference
design as compact as possible, while including all the features that enable the ST7580 to
perform at its best.
The information provided in this application note refers to the EVALST7580-1 reference
design.
