The Microchip's SAM4CP16B is a Smart Metering platform based on a high performance 32-bit, dual core ARM Cortex-M4 RISC processor providing maximum speed of 120 MHz each, 1Mbytes of embedded Flash, 128 Kbytes of SRAM and on-chip cache. SAM4CP16B includes an advanced cryptographic engine and embeds a modem for PRIME power line communication (PLC). PRIME (PoweR Line Intelligent Metering Evolution) is a mature, consolidated and worldwide PLC standard for Advanced Metering, Grid Control and Asset Monitoring applications. Microchip PRIME modem implementation includes enhanced PHY layer features such as additional robust modes and frequency band extension. The SAM4CP16B's unique dual ARM Cortex-M4 architecture supports implementation of signal processing, application and communications firmware in independent partitions.
