 本文主要介绍了铁电存储器FM20L08的原理及应用。该存储器不仅克服了EEPROM和Flash存储器写入时间长、擦写次数少等缺点,而且增加了电压监控器和软件控制的写保护功能,1MB的存储容量足以替代静态随机存储器。介绍FM20L08的引脚功能和工作原理,并在此基础上给出基于FM20L08的高速数据存储系统的设计方案及与单片机的接口电路。
Abstract:
 n this paper, features and application of FRAM memory FM20L08 are introduced.FM20L08 not only features the virtue of unlimited read/write cycles and no delay write,but also features of write protect low voltage lockout and software programmable block .1M byte wide memory logically organized as 131,072×8 has been designed to be a drop-in replace for standard? SRAMs .The pin description and some operations are introduced. The method of designing the interface circuit between the FM20L08 and the MCU for high speed data recorder is described.
