Abstract: Primary object of this application note is to demonstrate the use of various types of NV Memories with Dallas Semiconductor Microcontrollers. The article covers interconnections of the memories with the microcontrollers and details bus timing details required for this application. This article compares the pros and cons of the various nonvolatile memories available from various manufactures and the implementation of EEPROM technology into digital systems. In high-speed digital systems, where fast and unlimited read/write cycles are required, EEPROM memory is the only technology available. Other technologies with slower write times and a limited number of write cycles before "wearout" of the memory cell, are suitable for applications where only a limited number of write cycles and slow write times are acceptable. NV SRAMs are commonly used in data collection equipment, computers (configuration) and high-speed digital communication equipment (to store transient data during power failures). 你所查询的应用笔记提供Acrobat PDF格式： APPLICATION NOTE 170:Adding Nonvolatile SRAM into Embedded Systems (PDF, 263kB) 免费Acrobat PDF阅读软件可从以下网站获得： http://chinese-s.adobe.com/products/acrobat/readstep2.html 相关型号   APP 170: Jan 16, 2002 DS1230AB 256k非易失SRAM 完整的数据资料 (PDF, 288kB) 免费样品 DS1230Y 256k非易失SRAM 完整的数据资料 (PDF, 288kB) 免费样品 DS87C520 EPROM/ROM高速微控制器 完整的数据资料 (PDF, 716kB) 免费样品 自动更新 需要自动接收最新发布的应用笔记吗？请订阅EE-Mail™ (English only)。 我们期待您的反馈！ 喜欢？不喜欢？有待改善？或为我们提供建议？请与我们联系 — 我们将根据您的意见或建议改善我们的工作。 网页评价或提供建议   下载，PDF格式 (263kB)  AN170, AN 170, APP170, Appnote170, Appnote 170
