1. GENERAL DESCRIPTION
The W25X10BV (1M-bit), W25X20BV (2M-bit) and the W25X40BV (4M-bit) Serial Flash memories
provides 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 4mA active and 1A for power-down. All
devices are offered in space-saving packages.
The W25X10BV/20BV/40BV arrays are organized into 512/1,024/2,048 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 128 (32KB block erase), groups of 256 (block
erase) or the entire chip (chip erase). The W25X10BV/20BV/40BV 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 W25X10BV/20BV/40BV 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). SPI clock frequencies of up to 104MHz are supported allowing equivalent clock rates of
208MHz 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.
