STMicroelectronics STarGRID™ Power Line Networking System-on-Chip devices are designed to effectively address demanding smart-metering and smart-grid application requirements and related standards. STarGRID SoC devices optimize power consumption and system cost, making them an ideal choice for many green applications. These devices combine a high-performance digital signal processor (DSP) core with a programmable protocol engine, along with the full analog front end and power-line driver in a single chip, for a complete, flexible and cost-effective narrowband power-line communication solution. ST7570 SoC features S-FSK modulation up to 2.4 Kbit/s bit rate, and integrates a full turnkey IEC 61334-5-1 compliant protocol standard with new advanced communication features to address very cost-effective automatic meter-reading services and other command and control applications, such as street lighting control and sub-metering. ST7580 performs innovative dual-channel n-PSK modulation with high-performance convolutional coding and Viterbi decoding up to 28.8 Kbit/s. It is suitable for different protocol implementations, such as the open Meters & More specification. The high-performance ST7590 uses very robust OFDM modulation up to 128 Kbit/s, fully compliant with PRIME protocol standard specifications.
