The SAM4CP16C belongs to SMART energy portfolio. It is based on SAM4C, a high performance 32-bit, dual core ARM Cortex-M4 RISC processor embedding a G3 PLC [Power Line Communication] modem. The two cores Cortex-M4 are able to operate at a maximum speed of 120 MHz, featuring 1 Mbyte of embedded Flash, 128 kBytes of SRAM and on chip cache for each core.The SAM4CP16C is a flexible, compact and high-efficient device for a wide range of Smart Grid applications such as Smart Metering (Smart Meters and Data Concentrators), Lighting, Industrial/Home Automation, Home and Building Energy Management Systems, Solar Energy and Plug-in Hybrid Electric Vehicle (PHEV) Charging Stations.
