Winbond 25Q64 W25Q64JVSSIQ SOIC-8 ORIGINAL

1. GENERAL DESCRIPTIONS
The W25Q64JV (64M-bit) Serial Flash memory provides a storage solution for systems with limited space,
pins and power. The 25Q series offers flexibility and performance well beyond ordinary Serial Flash devices.
They are ideal for code shadowing to RAM, executing code directly from Dual/Quad SPI (XIP) and storing
voice, text and data. The device operates on 2.7V to 3.6V power supply with current consumption as low as
1µA for power-down. All devices are offered in space-saving packages.
The W25Q64JV array is organized into 32,768 programmable pages of 256-bytes each. Up to 256 bytes can
be programmed at a time. Pages can be erased in groups of 16 (4KB sector erase), groups of 128 (32KB
block erase), groups of 256 (64KB block erase) or the entire chip (chip erase). The W25Q64JV has 2,048
erasable sectors and 128 erasable blocks respectively. The small 4KB sectors allow for greater flexibility in
applications that require data and parameter storage.
