带有SHA-1引擎的iButton 1Kb EEPROM

DS1961S在坚固的iButton®器件内集成了1024位EEPROM、64位密钥、一个8字节的寄存器/控制页(其中包含五个用户读/写字节)、512位SHA-1引擎和一个全功能的1-Wire®接口。数据通过1-Wire协议串行传输，仅需要单根数据线和返回地线。DS1961S有一个称为暂存器的辅助存储区，在向主存储器、寄存器页写入数据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。在数据经过验证后，只要DS1961S接收到了匹配的160位信息认证码(MAC)，那么复制暂存器命令将把数据传送到最终的存储单元。MAC的计算涉及到存储在DS1961S中(包含器件的身份寄存器)的密 \n• 1128位5V EEPROM存储器，分为四页，每页256位，64位只写密钥和多达5个通用的读/写寄存器\n• 写访问需要知道密钥，并且能够计算和传送160位MAC，以便鉴别真伪\n• 可以对密钥和数据存储器加写保护(所有页或者仅第0页)，或者将它们置于EPROM仿真模式(\"write to 0\", 第1页)\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• 工作温度-40°C至+85°C，读写电压范围为2.8V至5.25V\n• 使用1-Wire协议，通过单根数据线与主机进行数据通信，传输速率可达14.1kbps\n• 内置16位CRC循环冗余码发;
