Description

Winbond W25Q64JVSSJQ is a 64‑Mbit serial flash memory device used to store firmware or other non‑volatile data. It is SPI‑based (with standard, fast read, and Quad I/O modes on some variants) and comes in an 8‑pin package (suffix SS/JQ indicates package type). The device typically operates from about 2.7 to 3.6 V. Memory organization is 8 MB, with data erasable in 4 KB sectors and larger blocks; it supports page programming (usually 256 bytes per write). Key features include Write Enable, status registers, sector/block protection, and power‑down modes. Common applications are storing boot code, firmware, and embedded data in microcontroller systems. For exact electrical characteristics, timing, endurance, and the full command set, consult the official Winbond datasheet specific to this variant.
