The Winbond W25Q64JVSSIQ is a serial NOR Flash memory from the SpiFlash® family, designed for electronic systems requiring compact, high-performance non-volatile storage with a low pin count.

It provides a capacity of 64 Mbit, equivalent to 8 MB, organised as 8M × 8 bits. Communication is provided through an SPI interface, including Dual and Quad I/O modes for faster data transfers, with a maximum clock frequency of 133 MHz.

Stored data is retained when power is removed, making the device suitable for firmware, bootloaders, configuration parameters, files, lookup tables, calibration data and other information used by microcontrollers and embedded systems.

The device operates from a 2.7 to 3.6 V power supply and supports an operating temperature range of −40°C to +85°C. Its 5.30 mm-wide SOIC-8 package is intended for surface mounting on printed circuit boards.

Important note

A capacity of 64 Mbit is equivalent to 8 MB, not 64 MB.

This component operates from a 2.7 to 3.6 V power supply. Before installation, verify the electrical requirements, pinout, package and communication protocol of the target equipment. It should not be connected directly to 5 V signals without suitable level-shifting circuitry.

This is an SMD component, so installation or replacement requires suitable electronic soldering equipment and experience.
