GENERAL DESCRIPTION
They are ideal for code download applications as well as storing voice, text and data. The devices operate on a single 2.3V to 3.6V power supply with current consumption as low as 4mA active and 1µA for power-down. All devices are offered in space-saving packages. The W25X10BL/20BL/40BL arrays are organized into 512/1,024/2,048 programmable pages of 256bytes 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 128 (32KB block erase), groups of 256 (block erase) or the entire chip (chip erase). The W25X10BL/20BL/40BL has 32/64/128 erasable sectors and 2/4/8 erasable 64KB blocks respectively. The small 4KB sectors allow for greater flexibility in applications that require data and parameter storage. (See figure 2.) The W25X10BL/20BL/40BL supports the standard Serial Peripheral Interface (SPI), and a high performance dual output as well as Dual I/O SPI: Serial Clock, Chip Select, Serial Data DI (I/O0), DO (I/O1).
