The ST8500 is a fully programmable power-line communication (PLC) modem system-on-chip (SoC), which is able to run any PLC protocol in the frequency band up to 500 kHz. The device architecture has been designed to target CENELEC EN50065, FCC and ARIB compliant applications supporting all major PLC protocol standards such as ITU G.9904 (PRIME), ITU G.9903 (G3-PLC®) and many other possible PLC protocol specifications and evolutions.
