pic external ram

dou you have any example for using external ram with pic16f877
if you have sch very good for me
 


pic+external ram

but i think when u need to access external ram with pic IOs this will take more time than accessing the internal ram so u must take this into consideration
 

picexternal memory interface

Yes you are right, but when you need more data memory, this is unique solution, because PIC don't have external bus to address memory
