W25Q64FWZPIF

Memory IC Overview

The W25Q64FWZPIF is a 64M-bit (8M x 8) Serial NOR Flash memory from Winbond, operating on a single 1.65V to 1.95V supply. It supports Standard, Dual, and Quad SPI interfaces with clock frequencies up to 104MHz. The device features uniform 4KB sectors for flexible data storage and includes advanced security registers. It is housed in an 8-pad WSON 6x5-mm package.

Memory IC Feature Summary

• Supports Standard, Dual, and Quad SPI protocols alongside QPI mode for high-speed data transfer.
• Features uniform 4KB sector architecture enabling granular erase operations.
• Includes hardware write protection via dedicated pins and software-configurable block protection.
• Provides execute-in-place (XIP) capability through continuous read modes.

Memory IC Applications

• Code shadowing to RAM
• Executing code directly from the SPI bus (XIP)
• Storing voice, text, and data in space-constrained systems

Memory IC Procurement Notes

Verify the specific suffix ZPIF against official datasheets to confirm the WSON 6x5-mm package and tape-and-reel delivery format. Confirm RoHS compliance status and moisture sensitivity levels prior to integration. Ensure voltage requirements align with the 1.65V-1.95V specification range.

Memory IC Selection Notes

Select this component for applications requiring low-voltage operation and compact footprint. The 1.8V variant is distinct from 3.0V or 3.3V versions; verify supply compatibility. Consider the WSON package for size constraints versus SOIC alternatives.

Memory IC Part Context

This part belongs to the W25Q64FW series of 1.8V Serial Flash memories. It shares architectural similarities with other W25Q devices but is optimized for ultra-low power consumption. The family supports various packages including SOIC, VSOP, and WLCSP.

Memory IC Replacement Considerations

Direct substitutes include W25Q64JWSSIQ and W25Q64JWSSIM. Verify pinout and voltage specifications when replacing with higher voltage variants like the JV series.
