Getting started with the X-NUCLEO-PLM01A1 expansion board
based on ST7580 for STM32 Nucleo
Introduction
The X-NUCLEO-PLM01A1 expansion board for STM32 Nucleo is based on the ST7580 FSK, PSK
multi-mode power line networking system-on-chip. It provides an affordable and easy-to-use solution for
the development of connectivity applications based on power line communication. It lets you easily
evaluate the communication features of the ST7580 based on a DC two-wire link between two boards.
You can also perform evaluation on an AC power line by connecting the X-NUCLEO-PLM01A1 to an
STEVAL-XPLM01CPL board providing effective AC coupling and isolation. The X-NUCLEO-PLM01A1
is interfaced with the STM32 controller via UART and GPIO pins and is compatible with the Arduino
UNO R3 (default configuration) and ST morpho (optional) connectors.

3.5 ST7580 device
The ST7580 FSK, PSK multi-mode power line networking system on chip is based on a
dual digital core architecture (a processor engine and a protocol controller core) to
guarantee excellent communication performance with a high level of flexibility. It has been
built on a multi-power technology with state-of-the-art VLSI CMOS lithography.
A hardware 128-bit AES encryption block (with customizable key management) is available
on chip when secure communication is requested.
The on-chip analog front end featuring analog-to-digital and digital-to-analog conversion,
automatic gain control and the integrated power amplifier delivering up to 1 A rms output
current make the ST7580 a unique system on chip for power line communication.
Safe and performing operations are guaranteed while keeping power consumption and
signal distortion levels very low, thus making the ST7580 an ideal platform for the most
stringent application requirements and regulatory standards compliance.
