The W25X10A (1M-bit), W25X20A (2M-bit), W25X40A (4M-bit) and W25X80A (8M-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 W25X10A/20A/40A/80A 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 W25X10A/20A/40A/80A 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. (See figure 2.)
The W25X10A/20A/40A/80A supports the standard Serial Peripheral Interface (SPI), and a high
performance dual output SPI using four pins: Serial Clock, Chip Select, Serial Data I/O and Serial
Data Out. SPI clock frequencies of up to 100MHz are supported allowing equivalent clock rates of
200MHz when using the Fast Read Dual Output instruction. These transfer rates are comparable to
those of 8 and 16-bit Parallel Flash memories.
A 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.
