2048k非易失SRAM

DS1249 2048k非易失(NV) SRAM為2,097,152位、全靜態(tài)非易失SRAM，按照8位、262,144字排列。每個NV SRAM均自帶鋰電池及控制電路，控制電路連續(xù)監(jiān)視VCC是否超出容差范圍，一旦超出容差范圍，鋰電池便自動切換至供電狀態(tài)、寫保護將無條件使能、防止數(shù)據(jù)被破壞。該器件沒有寫次數(shù)限制，可直接與微處理器接口、不需要額外的支持電路。 ? 在沒有外部電源的情況下最少可以保存數(shù)據(jù)10年\n? 掉電期間數(shù)據(jù)被自動保護\n? 沒有寫次數(shù)限制\n? 低功耗CMOS操作 \n? 70ns的讀寫存取時間 \n? 第一次上電前，鋰電池與電路斷開、維持保鮮狀態(tài)\n? ±10% VCC工作范圍(DS1249Y) \n? 可選擇±5% VCC工作范圍(DS1249AB)\n? 可選的-40°C至+85°C工業(yè)級溫度范圍，指定為IND\n? JEDEC標準的32引腳DIP封裝;
