W25Q64FWZPIQ TR

Memory IC Overview

The W25Q64FWZPIQ TR is a 64M-bit (8M-byte) NOR flash memory from Winbond, operating on a single 1.65V to 1.95V supply. It features an 8-pin WSON-8 package and supports SPI clock frequencies up to 104 MHz. The device offers Dual/Quad SPI and QPI modes for high-speed data transfer. It includes uniform 4KB sector erase capabilities, hardware write protection, and a 64-bit unique serial number.

Memory IC Feature Summary

• Supports standard, dual, and quad SPI interfaces along with Quad Peripheral Interface (QPI) for efficient code execution in place.
• Provides flexible architecture with uniform 4KB sectors and advanced security features including individual block protection and OTP locks.
• Operates within a wide temperature range of -40°C to +85°C with low power consumption for active and standby modes.

Memory IC Applications

• Code shadowing to RAM
• Execute In Place (XIP) applications
• Voice, text, and data storage

Memory IC Procurement Notes

Verify the specific revision status and lead times directly with Winbond Electronics or authorized distributors, as this component may have limited availability. Confirm that the WSON-8 packaging meets your board design requirements and that the 1.65V-1.95V voltage range aligns with your system's power supply specifications before finalizing procurement.

Memory IC Selection Notes

Select this component when a low-voltage, space-efficient NOR flash solution is required for embedded systems. Ensure compatibility with the 104 MHz SPI clock speed and verify that the 8-pin WSON-8 footprint fits the PCB layout. Consider the 4KB uniform sector size for applications requiring granular data protection and update flexibility.

Memory IC Part Context

This part belongs to the W25Q64FW series of SpiFlash memories designed for systems with limited space and power constraints. It is distinct from higher-capacity models like the W25Q128 or different voltage variants such as the 3V W25Q64JV. The ZPIQ suffix indicates the specific WSON-8 package and tape-and-reel shipping configuration.

Memory IC Replacement Considerations

Direct substitutes include other W25Q64FW variants with different packages, such as W25Q64FWSSIQ (SOIC-8). Verify pin compatibility and voltage specifications when considering alternatives from the same family.

Memory IC FAQ

What is the maximum SPI clock frequency supported by the W25Q64FW?

The device supports SPI clock frequencies of up to 104 MHz.

How does the Quad Enable (QE) bit affect pin functionality?

When the QE bit is set for Quad I/O operation, the /WP pin functions as IO2 and the /HOLD pin functions as IO3.
