Trying to use library for SPX-17115 (Serial Flash - 128Mbit) for same family chip Winbond(W25N01G)

Hi, Paul (and Nathan).

Thank you for offering a library for the Serial Flash chip - 128mb W25Q128JV. I wonder if this same library would work for a bit of a larger capacity Flash (W25N01G).

I’ve used Teensy 4.1 board with same chip but I know their library won’t work for Artemis board.

Again thank you for your libraries!

Hi,

Looking at the INSTRUCTIONS in the datasheets for the two chips, I am seeing several differences. The way the chip is erased looks very different: Chip Erase on the Q128 vs. Block Erase on the N01. The read addressing looks different too: 24-bit on the Q128 vs. 16-bit column addressing on the N01 (when BUF=1).

I think the library will not work correctly and would need to be modified for the N01…

I hope this helps,

Paul

Paul,

Thank you for your advice. I will check the code thoroughly. Perhaps Sparkfun can add flash drives with a higher capacity to its product list in the near future!
