1. GENERAL DESCRIPTION
The W25Q32V (32M-bit) Serial Flash memory provides a storage solution for systems with limited space,
pins and power. The 25Q series offers flexibility and performance well beyond ordinary Serial Flash
devices. They are ideal for code shadowing to RAM, executing code directly from Dual/Quad SPI (XIP)
and 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 1µA for power-down. All devices are offered in space-saving
packages.
The W25Q32V array is organized into 16,384 programmable pages of 256-bytes each. Up to 256 bytes
can be programmed at a time. Pages can be erased in groups of 16 (sector erase), groups of 128 (32KB
block erase), groups of 256 (64KB block erase) or the entire chip (chip erase). The W25Q32V has 1,024
erasable sectors and 64 erasable blocks respectively. The small 4KB sectors allow for greater flexibility in
applications that require data and parameter storage. (See figure 2.)
The W25Q32V supports the standard Serial Peripheral Interface (SPI), and a Dual/Quad output as well
as Dual/Quad I/O SPI: Serial Clock, Chip Select, Serial Data I/O0 (DI), I/O1 (DO), I/O2 (/WP), and I/O3
(/HOLD). SPI clock frequencies of up to 80MHz are supported allowing equivalent clock rates of 160MHz
for Dual Output and 320MHz for Quad Output when using the Fast Read Dual/Quad Output instructions.
These transfer rates can outperform standard Asynchronous 8 and 16-bit Parallel Flash memories. The
Continuous Read Mode allows for efficient memory access with as few as 8-clocks of instruction-
overhead to read a 24-bit address, allowing true XIP (execute in place) operation.
A Hold pin, Write Protect pin and programmable write protection, with top or bottom array control,
provide further control flexibility. Additionally, the device supports JEDEC standard manufacturer and
device identification with a 64-bit Unique Serial Number.
