[原创] Lattice L－ASC10和Platform Manager 2硬件管理设计方案

Lattice公司的Platform Manager 2和L-ASC10是系统可编程的硬件管理(电源,热和控制台)扩展器,能无缝地对电源电压和电流监测,温度监测,时序和裕度控制通路.器件包括支持监视信号状态和输出控制信号的专用接口和中央硬件管理控制器,主要用在通信和网络设备,工业控制,测试测量,医疗电子,存储设备和服务器.本文介绍了L-ASC10主要特性,ASC框图和硬件管理应用框图以及平台管理2评估板框图,电路图和材料清单.

The L-ASC10 (Analog Sense and Control - 10 rail) is a Hardware Management (Power, Thermal, and Control Plane Management) Expander designed to be used with Platform Manager 2 or MachXO2 FPGAs to implement the Hardware Management Control function in a circuit board. The L-ASC10 (referred to as ASC) enables seamless scaling of power supply voltage and current monitoring, temperature monitoring, sequence and margin control channels. The ASC includes dedicated interfaces supporting the exchange of monitor signal status and output control signals with these centralized hardware management controllers. Up to eight ASC devices can be used to implement a hardware management system. The ASC provides three types of analog sense channels: voltage (nine standard channels and one high voltage channel), current (one standard voltage and one high voltage), and temperature (two external and one internal)。
