PowerCap，帶有晶振

DS9034PCX PowerCap作為非易失性計時RAM的鋰電源，采用Dallas Semiconductor的直接表面貼裝PowerCap模塊(PCM)封裝。PowerCap模塊板焊接到位并清潔后，將DS9034PCX PowerCap放置在PCM板頂部，形成完整的PowerCap模塊封裝。PowerCap采用鍵控設(shè)計，可防止錯誤連接。\n\n DS9034PCX可以輕松拆卸，只需將普通螺絲刀插入分離功能中，然后輕輕地向外和向上撬動，將PowerCap從PowerCap模塊板上松開即可。\n\n; ? 為PowerCap模塊封裝(PCM)中的非易失性計時RAM提供10年的電池備用電源\n\n? 直接卡合在表面貼裝的PowerCap模塊板上\n\n? 分離功能便于輕松拆卸\n\n? 與這些34引腳PowerCap模塊板兼容：\n?
