I'm wondering if it's possible to use the smaller version of the W25Q128FV in the audio adapter?
I have a W25Q32FVSIG that has exactly the same pinout as the one recommended for the audio adapter but obviously has 1/4 the storage space.
The W25Q32FV array is organized into 16,384 programmable pages of 256-bytes each. Up to 256 bytes
can be programmed at a time. Pages can be erased in groups of 16 (4KB sector erase), groups of 128
(32KB block erase), groups of 256 (64KB block erase) or the entire chip (chip erase). The W25Q32FV
has 1,024 erasable sectors and 64 erasable blocks respectively. The small 4KB sectors allow for greater
flexibility in applications that require data and parameter storage.
The W25Q128FV array is organized into 65,536programmable pages of 256-bytes each. Up to 256 bytes
can be programmed at a time. Pages can be erased in groups of 16 (4KB sector erase), groups of 128
(32KB block erase), groups of 256 (64KB block erase) or the entire chip (chip erase). The W25Q128FV
has 4,096 erasable sectors and 256 erasable blocks respectively. The small 4KB sectors allow for greater
flexibility in applications that require data and parameter storage.
ALSO...
I also have a Macronix MX25L1606E that has the same pinout and after looking at the "Instruction Set Table" of the Winbond chip and comparing it to the "COMMAND DESCRIPTION" table of the MXIC chip they seem to be the same instructions. Of course it's quite small so it's not terribly useful.
