Microchip Technology ATSAM4CMP32CA-AU

Description

The SAM4CP series belongs to Atmel® │SMART energy portfolio. It is based on SAM4C, a high performance 32-bit, dual core ARM® Cortex®-M4 RISC processor embedding a PRIME PLC [Power Line Communication] modem. The cores 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.
SAM4CP unique dual ARM Cortex-M4 architecture supports implementation of signal processing, application and communications firmware in independent partitions. SAM4CP16B system-on-chip includes a PRIME modem, being PRIME [PoweR line Intelligent Metering Evolution] an open standard technology used for Smart Grid applications, mainly Smart Metering. Atmel PRIME modem implementation includes enhanced PHY layer features such as additional robust modes and frequency band extension.
