          DS1647

          Nonvolatile Timekeeping RAM

          DESCRIPTION The DS1647 is a 512k x 8 nonvolatile static RAM with a full-function real-time clock, which are both accessible in a byte-wide format. The nonvolatile timekeeping RAM is functionally equivalent to any JEDEC standard 512k x 8 SRAM. The device can also be easily substituted for ROM, EPR

          非易失時鐘RAM

          DS1647為512k x 8非易失性靜態(tài)RAM,包括一個完備的實(shí)時時鐘,兩者均以字節(jié)寬度格式訪問。非易失性時間保持RAM功能等價于任何一款JEDEC標(biāo)準(zhǔn)的512k x 8 SRAM。該器件也能夠輕松替代ROM、EPROM及EEPROM,提供讀/寫非易失性以及增加實(shí)時時鐘功能。實(shí)時時鐘信息占用8個最高端RAM地址。RTC寄存器包括年、月、日、星期、時、分、秒等數(shù)據(jù),以24小時制、BCD編碼格式表示。對于每月天數(shù)及閏年的修正是自動完成的。RTC時鐘寄存器是雙緩沖的,以避免在時鐘更新循環(huán)期間可能引起的不正確數(shù)據(jù)存取。雙緩沖系統(tǒng)也能阻止存取時間寄存器數(shù)據(jù)時所引起的時間損失。DS1647還包含自身電源 \n? 集成了NV SRAM、實(shí)時時鐘、晶振、電源失效控制電路及鋰電池 \n? 時鐘寄存器訪問方式等同于靜態(tài)RAM,這些寄存器占用8個高端RAM地址 \n? 無電源供電時,可保持非易失性10年以上 \n? BCD編碼的世紀(jì)、年、月、日、星期、時、分、秒,同時具有自動閏年補(bǔ)償至2100年 \n? 電源失效寫保護(hù)允許±10% VCC電源容差 \n? DS1647 (DIP模塊): \n? 標(biāo)準(zhǔn)JEDEC字節(jié)寬度128k x 8 RAM引腳 \n? DS1647P (PowerCap模板): \n? 表面可貼裝的封裝形式,直接連接到包括電池和晶振的PowerCap模塊 \n? 電池可更換(P;
