W25Q40EWUXIE

Memory

4 Mbit1.8 VSPI flashQuad SPIQPIUSON-8

W25Q40EWUXIE is a 4 Mbit, 1.8 V-class serial NOR flash for compact embedded storage using SPI, Dual/Quad SPI, or QPI. The UXIE option is an 8-pad USON 2 mm × 3 mm package.

Best for

  • Compact 1.8 V embedded firmware storage
  • Industrial embedded controllers
  • Dual/Quad SPI read applications

Avoid if

  • The system only provides a 3.3 V flash supply
  • A larger than 4 Mbit nonvolatile memory is required
  • The design requires dedicated /WP or /HOLD functionality while using Quad I/O

Check before use

  • Confirm the PCB footprint for the USON-8 2 mm × 3 mm package
  • Confirm the controller supports the selected SPI or QPI command mode
  • Validate current procurement status with an active supplier quote
