1Kb、保护型1-Wire EEPROM，带有SHA-1引擎

DS2432在单个芯片内集成了1024位EEPROM、64位密钥、8字节寄存器/控制页(其中包含5个用户读/写字节)、512位SHA-1引擎和一个全功能的1-Wire接口。每个DS2432具有自身的、由工厂刻入的64位ROM注册码，可确保唯一识别、绝对可溯。数据按照1-Wire协议串行传送，只需一根数据线或返回地线。DS2432有一个称为暂存器的辅助存储区，在向主存储器、寄存器写入数据时，或者在安装新密钥时充当缓冲器。数据首先被存入暂存器，并可从这里读回。经过验证后，假定DS2432接受到匹配的160位MAC，那么Copy Scratchpad (复制暂存器)命令将把数据传送到最终的存储单元。 • 1128位5V EEPROM存储器，分为四页，每页256位，64位只写密钥和多达五个通用读/写寄存器\n• 内置512位SHA-1引擎，用于计算160位信息鉴定码(MAC)或生成密钥\n• 写访问需要知道密钥，并且能够计算和传送160位MAC，以鉴别真伪\n• 可以对密钥和数据存储器加写保护(所有页或者只是第0页)，或者将它们置于EPROM仿真模式(“写入0”，第 1页)\n• 唯一的、由工厂光刻并经过测试的64位注册号，保证绝对可溯，因为没有任何两个注册号相同的器件\n• 内置多点控制，保证兼容于其它1-Wire网络产品\n• 将控制、寻址、数据和供电集于一个数据引脚\n• 与微处理器的;
