W25Q64JV (64Mbits/8Mbyte) Flash Storage Module

The 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. The device operates on 2.7V to 3.6V power supply with current consumption as low as 1µA for power-down.

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 2048 erasable sectors and 64 erasable blocks respectively.

The small 4KB sectors allow for greater flexibility in applications that require data and parameter storage. The W25Q64JV module supports the standard Serial Peripheral Interface (SPI) : CLK, /CS, DI, DO.

The clock frequencies of up to 133MHz are supported. Additionally, the device supports JEDEC standard manufacturer and device ID and SFDP Register, a 64- bit Unique Serial Number and three 256-bytes Security Registers.
