CC3220SF: External SPI Interface for the NAND Flash

Valentyn Korablov

Part Number: CC3220SF

Hi everyone,

for the device CC3220SF12RGK, can I connect to this interface a NAND Flash (W25N01GVZEIT) and use this Flash for storing user data (for example media files). Off course, user application code, I would like load from a Internal (XIP) 1MB Flash.

Hi,

SPI flash (sFlash) is mandatory for function of CC3220SF devices and is used as storage for WiFi coprocessor (called NWP). You haven't direct access into this SPI flash chip. You can use sl_ filesystem and store there your own user data. Detail information about filesystem and supported flash chip you find here.
