The W25Q32BV (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 device operates on a single 2.7V to 3.6V power supply with current

consumption as low as 4mA active and 1μA for power-down.

The W25Q32BV 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 (4KB sector erase), groups of 128

(32KB block erase), groups of 256 (64KB block erase) or the entire chip (chip erase). The W25Q32BV

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 W25Q32BV supports the standard Serial Peripheral Interface (SPI), and a high performance

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 104MHz are supported allowing

equivalent clock rates of 208MHz (104MHz x 2) for Dual I/O and 320MHz (80MHz x 4) for Quad I/O when

using the Fast Read Dual/Quad I/O 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.
