摘　　要：PIC1 6F877可采用 MSSP模块的 SPI方式扩展大容量数据存储器 ,74HC1 65和 74HC5 95分别实现串 -并和并 -串转换以模拟片外数据总线 ,而 RB口用于产生控制读写的信号线 ,KM2 9N1 60 0 0 TS的SPI way of MSSP module can be adopted by PIC16F877 to expand the large capacity of data memory, in order to analogize data bus of outside chip, 74HC165 and 74HC595 can realize the change-over respectively from series to parallel and from parallel to series. RB interface is used for generating information line of controlling reading and writing and 8-signal-conveyor ways of KM29N16000TS offers a simple way to realize the data line connected with address line.
