Analog Devices / Maxim Integrated DS2431 1024位1线® EEPROM
Maxim DS2431是一款1024位、1线® EEPROM芯片，各芯片都具有四个256位的存储器页。数据被写入一个8字节暂存器，经验证后复制到EEPROM存储器。Maxim IC DS2431的四个存储器页可进行单独写保护或置于EPROM仿真模式，此时只能将各位状态从1变为0。DS2431 EEPROM芯片通过单导体1线总线进行通信。通信遵循标准的1线协议。每个DS2431设备均有其自身不可改变且唯一的64位ROM注册号，该号在工厂时用激光刻入芯片。注册号用于对多点1线网络环境中的该设备进行寻址。这些Maxim EEPROM设备设计用于各种应用，包括附件/ PCB识别、医疗传感器校准数据存储和模拟传感器校准。
