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 W25X10/20/40/80 array is organized into 512/1024/2048/4096 programmable pages of 256-bytes each. Up to 256 bytes can be programmed at a time using the Page Program instruction. Pages can be erased in groups of 16 (sector erase), groups of 256 (block erase) or the entire chip (chip erase). The W25X10/20/40/80 has 32/64/128/256 erasable sectors and 2/4/8/16 erasable blocks respectively. The small 4KB sectors allow for greater flexibility in applications that require data and parameter storage.
Hold pin, Write Protect pin and programmable write protect, with top or bottom array control features, provide further control flexibility. Additionally, the device supports JEDEC standard manufacturer and device identification.
