A COMPLETE PLATFORM
The ST75MM device is a flexible power line
communication system-on-chip combining
a high performing PHY processor and
a protocol controller core implementing
the turnkey Meters & More protocol, for
future‑proof, compact and cost effective
advanced metering infrastructure solutions.
The high-performing ST7590 uses very
robust OFDM modulation up to 128 Kbit/s,
fully compliant with PRIME protocol standard
specifications.
The STarGRID platform has been developed
to meet specific standards and market
requirements.
The ST7570 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 advanced communication
features to address very cost-effective
automatic meter- reading services.
The ST7580 performs innovative dual
channel n-PSK modulation with high
performance convolutional coding and Viterbi
decoding up to 28.8 Kbit/s, and it is suitable
for different protocol implementations, to
satisfy communication needs for customized
smart metering and many green applications,
but also smart-energy control in photovoltaic
modules, factory and home automation,
home area networking and street lighting
management.
