GENERAL DESCRIPTION
The W25X32A (32M-bit) Serial Flash memory 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 1A for power-down. All devices are offered in space-saving packages.
The W25X32A array is organized into 16,384 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 W25X32A has 1,024
erasable sectors and 64 erasable blocks. The small 4KB sectors allow for greater flexibility in applications
that require data and parameter storage. (See figure 2.)
The W25X32A 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.
