铁电存储器在单片机数据采集系统中的应用

本文结合PIC16F877A单片机采集系统，采用二线制12C串行总线方式，给出铁电存储器FM24C64与PIC16F877A单片机的硬件接口电路图，简化线路板的空间。而且，还介绍了关于铁电存储器FM24C64的基本时序，读写过程，及其软件设计的步骤。这种设计方案节省功耗、成本，克服了EEPROM或者其他非易失性存储器的不足，提高了采集系统工作稳定，陛和可靠性，可以广泛的用于PIC单片机产品的开发和研制。

The Application of Ferro-Electric RAM to Data Processing and Correspondence of SCM Data Acquisition System

With the system of PIC16F877A Single Chip Microcontroller Data Acquisition, This paper describes the hardware interface circuit between ferroelectric RAM FM24C64 and PIC16F877A MCU by second-line I^2C serial bus. And, the basic timing, reading and writing process, and the steps of software designing on ferroelectric RAM FM24C64, are introduced in this paper. This design proposal saves power consumption and cost, overcomes the shortcoming of EEPROM or other non-volatile memory, improves the stability and reliability of Acquisition system, and can be widely used for research and development of PIC products.
