W25 Flash driver

crates.io Documentation

This is a generic async driver for the W25 flash chips from Winbond.

Supported series:

  • Q
  • X

More series support is welcomed!

Defmt is also supported through the defmt feature.

This crate is adopted from https://github.com/tweedegolf/w25q32jv

TODO

  • Fast read support. So far there's only support for the normal read, so don't use a SPI speed of > 50Mhz

Changelog

Unreleased

0.6.0 2025-07-07

  • Continued from https://github.com/tweedegolf/w25q32jv 0.5.1
  • Driver and driver struct has been renamed to W25
  • Series is now a generic so the driver can support multiple series
  • The capacity is now given at runtime so we don't need feature flags
