The Atmel SAM4CP16B is an extension of Atmel’s SAM4Cx smart energy platform built on a dual-core 32-bit ARM® Cortex®-M4 architecture. Fully compatible with Atmel’s ATPL230A OFDM physical layer (PHY) device compliant with PRIME standard specification, this highly flexible solution addresses OEM’s requirements for various system partitioning, BOM reduction and time-to-market requirements by incorporating independent application, protocol stack and physical layer processing functions within the same device.
