Device overview

Made using multi-power technology with state-of-the-art VLSI CMOS lithography, the

ST7580 is based on dual digital core architecture (a PHY processor engine and a protocol

controller core) to guarantee outstanding communication performance with a high level of

flexibility for either open standards or customized implementations.

A HW 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, plus the integrated power amplifier delivering up to 1 A RMS output

current makes the ST7580 a unique system-on-chip for power line communication.

Line coupling network design is also simplified, leading to a very low cost BOM.

Robust and performing operations are guaranteed while keeping power consumption and

signal distortion levels very low; this makes the ST7580 an ideal platform for the most

stringent application requirements and regulatory standards compliance.
