Smart Grid Solutions: Smart Grid Distribution/Smart Meters Slide 41

A poly-phase meter implementation, as previously mentioned, does not use the standard meter chip, but the STPMC1 or S1 or S2. With the poly-phase meter implementation, the reference design embeds the anti-tampering function with ST’s MEMS. IrDA transmission with USB connectivity is being used as well, with fully embedded power management from ST. In this case, the power line is being used for communication. The STEVAL-IPP001V2 is a more complex board with more features, higher sensitivity, and embedded FreeRTOS firmware that can be modified for the customer’s use. A special card is used to support the Smartcard interface, with a ZigBee connector and the dual EEPROM as well. This modular solution is a complete meter with ST capability embedded.
