20Kb 1-Wire EEPROM

DS28EC20是一款20480位、1-Wire® EEPROM，分为80个256位的存储器页。器件提供一个额外的页用于控制功能。数据被写入一个32字节暂存器，经过校验后，复制到EEPROM存储器。器件具有一个特殊功能，可以将8个存储器页设置为写保护或EPROM仿真模式，在EPROM仿真模式下各个位仅能由1修改为0状态。DS28EC20通过单个触点的1-Wire总线进行通信，遵循标准1-Wire协议。各个器件均具有不可修改的、64位唯一ROM注册码，由工厂光刻入芯片。该注册码可用于在多节点1-Wire网络环境中寻址器件。\n\n • 20480位非易失性(NV) EEPROM被分为80个256位页\n• 独立的一块8页存储器(块)可以设置为永久的写保护或OTP EPROM仿真模式(“写为0”)\n• 读写访问高度向后兼容以前的器件(例如，DS2433)\n• 256位暂存器，遵循严格的读/写协议，确保数据传输的完整性\n• +25°C温度下200k擦写次数\n• 工厂编程的64位唯一注册码，确保无错的器件选择和绝对的器件识别\n• 开关滞回和滤波优化噪声性能\n• 使用1-Wire协议以15.4kbps或125kbps速率与主机进行通信\n• 低成本TO-92封装\n• 工作范围：5V ±5%，-40°C至+8;
