    flash memory

      I need to connect a flash memory (AM29F032) to upload/download the content of a USB pen drive (I use a CY8CKIT 030)

         

      Can someone help me to design it?

         

      Thank you

          The AM29F032 is a fully parallel part, hence the interface is brute force, 22 pins

             

          needed for address, 8 for data, and pins for OE. WE, CE. The address data has

             

          to be split across 3 ports. A read is simple, present address, 22 bits, and set OE and

             

          CE low, and follow the buss operations table to do the read.

             

           

             

          If the sacrifice in pins is too high you could use a serial to parallel external SR part,

             

          or a supper low costs PSOC 1 programmed as a serial to parallel converter.
