The 25Q64 (64M-bit) Serial Flash memory provides a storage solution for systems with limited space, pins and power. The 25Q64 offers flexibility and performance well beyond ordinary Serial Flash devices. The device operates on a single 1.65V to 1.95V power supply with current consumption as low as 4mA active and 1µA for power-down. The 25Q64 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 W25Q64 has 4,096 erasable sectors and 256 erasable blocks respectively. The small 4KB sectors allow for greater flexibility in applications that require data and parameter storage.
