1-Wire SHA-1認證

DS28E10在單一芯片內把一次性編程224位用戶EPROM與符合FIPS 180-3安全散列算法(SHA-1)的質詢-響應安全認證功能結合在一起。一旦寫入數據，存儲器將自動開啟寫保護。此外，每一個器件帶有唯一的64位ROM注冊碼(ROM ID)，由工廠刻入芯片。每次可向存儲器寫入4個字節(jié)，安全的低成本工廠編程服務可對器件數據進行預編程，這也包括SHA-1安全數據部分。器件通過單觸點1-Wire?總線進行通信，遵循標準的1-Wire協議，ROM ID在多器件1-Wire網絡中充當節(jié)點地址。\n\n ? 專用的硬件加速SHA-1引擎產生SHA-1 MAC\n? 一頁28字節(jié)用戶OTP EPROM\n? 不可逆寫保護\n? 唯一的工廠編程64位識別碼\n? 1-Wire接口支持標準速率和高速驅動\n? 以15.4kbps標準速率或高達125kbps的高速模式與主機通信 \n? 工作在2.8V至3.6V供電范圍和-40°C至+85°C溫度范圍\n? 3引腳SOT23和6引腳TSOC封裝\n? 1-Wire和VCC引腳具有±6kV (典型值)人體模式(HBM) ESD保護;
