STCOMET

Smart Metering system-on-chip
  • Preview Preview

The STCOMET is a device that integrates a narrow band power line communication modem, a high-performance application core and metrology functions in a single chip.

The PLC modem architecture has been designed to address EN50065, FCC, ARIB compliant PLC applications. Together with the application core, it enables the STCOMET to support multiple narrow band PLC standards such as PRIME, IEC61334-5-1, G3-PLC, METERS AND MORE, P1901.2 and many others.

The high accuracy metrology sub-system is suitable for EN 50470-1, EN 50470-3, IEC 62053-21, IEC 62053-22 and IEC 62053-23 compliant class1, class0.5 and class0.2 AC metering applications.
