1-Wire SHA-1认证器，具有1Kb EEPROM，工作在1.8V

DS28E02将1024位EEPROM与符合FIPS 180-3安全散列算法(SHA-1)的质询-响应安全认证功能结合在一起。1024位EEPROM阵列被配置为四页，每页256位，且带有64位暂存器用于执行写操作。所有存储页面都可以设置为写保护模式，并可将其中一页置于EPROM仿真模式，该模式下数据位只能从1变为0。每片DS28E02带有各自唯一的64位ROM注册码，由工厂刻入芯片。DS28E02通过单触点1-Wire®总线进行通信，遵循标准的1-Wire协议，注册码在多器件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)并生成密钥 \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• 四个存储器页中的第0页和第3页或全部页面可由用户编程设置为写保护 \n• 第1页可被置于用户可编程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实现，遵循1-Wire协议，通信速率为12.5kbps或35.7kbps \n• 切换点滞回和滤波优化了信号通信的抗噪声性能 \n• 在-20°C至+85°C温度范围、1.75V至3.65V较宽的供电电压;
