超高精度、SPI總線RTC，集成晶體和SRAM

DS3234是一款低成本、超高精度、采用SPI?總線的實(shí)時(shí)時(shí)鐘(RTC)，集成了溫度補(bǔ)償晶體振蕩器(TCXO)和晶體。DS3234內(nèi)置經(jīng)過(guò)溫度補(bǔ)償?shù)木茈妷夯鶞?zhǔn)和比較器電路用來(lái)監(jiān)視VCC。當(dāng)VCC跌落至低于電源失效電壓(VPF)時(shí)，器件產(chǎn)生/RST輸出；當(dāng)VCC跌落至同時(shí)低于VPF和VBAT時(shí)，器件將禁止讀/寫訪問(wèn)。器件還對(duì)/RST引腳進(jìn)行監(jiān)視，可作為按鈕輸入以產(chǎn)生μP復(fù)位。當(dāng)器件的主電源中斷時(shí)，器件切換至備用電源輸入以保持精確的計(jì)時(shí)。集成的晶體諧振器增強(qiáng)了器件的長(zhǎng)期精度同時(shí)減少了生產(chǎn)線上的零件數(shù)量。DS3234提供商業(yè)級(jí)和工業(yè)級(jí)溫度范圍，并采用工業(yè)標(biāo)準(zhǔn)300mil、20引腳SO封裝。\n\n ? 在0°C至+40°C范圍內(nèi)，精度為±2ppm\n? 在-40°C至+85°C范圍內(nèi)，精度為±3.5ppm\n? 為不間斷計(jì)時(shí)提供電池備份輸入\n? 工作溫度范圍 \n? 商業(yè)級(jí)：0°C至+70°C \n? 工業(yè)級(jí)：-40°C至+85°C\n\n\n? 低功耗\n? 實(shí)時(shí)時(shí)鐘計(jì)數(shù)秒、分、時(shí)、星期、日期、月份和年份信息，具有有效至2099年的閏年補(bǔ)償\n? 提供每天兩個(gè)定時(shí)鬧鐘\n? 可編程方波輸出\n? 4MHz SPI接口，支持模式1和3\n? 數(shù)字溫度傳感器輸出：精度為±3°C\n? 老化修正寄存器\n? /RST輸入/輸出\n? 300mil、20引腳SO封裝;
