Maxim公司的MAX79356是集成了模拟前端(AFE)的窄带正交频分复用(OFDM)动力线通信调制解调器(Modem)系统级(SoC)芯片,包括了两个流水线32位RISC(MAXQ®30E)处理器,和G3-PLC, IEEE 1901.2, ITU G9903, PRIME兼容,用于MAC和PHY的512KB 闪存和288KB RAM;还集成了用于加密和解密以及授权的28/256位AES和AES-CCM引擎,主要用在智能电网通信,智能电表,先进计量基础设备(AMI),工厂和建筑物自动化,电动汽车充电,家庭能量监视,太阳能和可再生能源管理.本文介绍了MAX79356主要优势和特性,框图,G3-PLC PHY框图,典型工作电路以及评估板MAX79356 EVK主要特性和优势,框图,电路图和材料清单.

ZENO™ (MAX79356) is a programmable narrowband orthogonal frequency division multiplexing (OFDM)-based powerline communication (PLC) modem system-on-chip (SoC) device that provides standards compliant high performance and secured powerline communication in a small package. ZENO integrates two pipelined 32-bit RISC (MAXQ®30E) processors to offer high performance and future-proof flexibility. These two 32-bit RISC proces­sors perform dedicated PHY signal processing functions and MAC layer functionality. Maxim provided, certified firmware images allow faster time to market. Factory or in-field firmware update feature allows adoption of changes and updates in PLC communication standards. The inte­grated high-speed AES-CCM* engine ensures standards compliant data communication security and integrity.
