描述：X5045S8IZT1
這些設備結合了四種流行的功能，開機復位控制、看門狗定時器、電源電壓監控、和塊鎖定保護串行 EEPROM 存儲器合二為一包裹。這種組合降低了系統成本，減少了板空間要求，并提高可靠性。給設備通電會激活上電復位保持 RESET/RESET 有效一段時間的電路時間。這允許電源和振蕩器穩定在處理器執行代碼之前。看門狗定時器提供獨立保護微控制器的機制。當微控制器未能在可選擇的超時間隔內重新啟動計時器，設備激活 RESET/RESET 信號。用戶從三個預設值中選擇間隔。一經選中，即使在循環電源后，間隔也不會改變。該器件的低 VCC 檢測電路可保護用戶的系統從低電壓狀態，重置系統當 VCC 低于最小 VCC 跳變點時。RESET/RESET 有效，直到 VCC 恢復正常運行水平并趨于穩定。四大行業標準 VTRIP閾值是可用的，但是，Intersil 的獨特電路允許重新編程閾值以滿足自定義要求或微調應用程序的閾值需要更高的精度。設備的內存部分是一個 CMOS 串行具有 Intersil 塊鎖定保護的 EEPROM 陣列。這陣列在內部組織為 512 x 8。該設備具有串行外設接口 (SPI) 和軟件協議允許在簡單的四線總線上運行。該設備采用 Intersil 專有的 Direct Write™ 單元，提供至少 100,000 次循環的耐用性和最小數據保留 100 年。
