I am looking for someone who would modify the schematics and PCB layout in the following reference design [login to view URL] . The idea is to add external EEPROM/flash memory to the MCU, so you need to update the provided Altium schematics and PCB layout. You should be careful to leave some pins on the part in a defined state so the memory stays enabled and ready to communicate. You must guarantee that the solution will work for sure, so MCU will be able to communicate via SPI with external memory. I am opened for suggestions about which memory to choose, but I believe that S25FL256SAGNFI001 or N25Q256A13EF840E should be a good choice.

Hello, S25FL256SAGNFI001 is good choice. because i have used it in one of my project and its work well. Secondary I can interface CC2541 with this SPI flash easily. and I am sure that it will work perfectly form hardware side. One more thing if you are redesign the board then you must know that your board contain antenna and its most critical thing in Board. As well as its contain FEM and RF layout is most critical layout. I can redesign board as i have 4+ years of experience of Board design.
