GENERAL DESCRIPTION The W25X16/W25X16A (16M-bit), W25X32 (32M-bit), and W25X64 (64M-bit) Serial Flash memories provide a storage solution for systems with limited space, pins and power. The 25X series offers flexibility and performance well beyond ordinary Serial Flash devices. They are ideal for code download applications as well as storing voice, text and data. The devices operate on a single 2.7V to 3.6V power supply with current consumption as low as 5mA active and 1µA for power-down. All devices are offered in space-saving packages. The W25X16/16A/32/
