1Kb、保护型1-Wire EEPROM，带有SHA-1引擎

DS28E01-100将1024位EEPROM与符合ISO/IEC 10118-3安全散列算法(SHA-1)的质询响应安全认证结合在一起。1024位EEPROM阵列被配置为四页，每页256位，且带有64位暂存器以执行写操作。所有的存储页面都可以设置为写保护模式，并可将其中某页置于EPROM仿真模式，即将数据位只能从1变为0。每片DS28E01-100带有唯一的64位ROM注册码，由工厂刻入芯片。DS28E01-100通过单触点1-Wire®串行接口进行通信，遵循1-Wire协议，在多个从器件的1-Wire网络中充当节点地址。\n\n • 1024位EEPROM存储器，分为4页，每页256位\n• 内置512位SHA-1引擎，用于计算160位信息认证码(MAC)或生成密钥\n• 写访问需要已知密钥, 并且能够计算和发送160位MAC作为认证\n• 四个存储器页中的页0、3或全部页面可由用户编程设置为写保护\n• 页1可被置于用户可编程的OTP EPROM仿真模式(“写为0”)\n• 与主机间的通信通过单根数字线即可进行，遵循1-Wire协议，通信速率为15.3kbps或90.9kbps\n• 切换点滞回和滤波优化了抗噪声性能\n• 可在-40°C至+85°C温度范围，2.8V至5.25V宽电压范围内进行读、写操作\n• 采用;
