– Allows true XIP (execute in place) operation – Continuous Read with 8/16/32/64-Byte Wrap – More than 100,000 erase/program cycles(1) – 104MHz Dual SPI / 80MHz Quad SPI clocks – Dual SPI: CLK, /CS, IO0, IO1, /WP, /Hold – Standard SPI: CLK, /CS, DI, DO, /WP, /Hold 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. These transfer rates can outperform standard Asynchronous 8 and 16-bit Parallel Flash memories. 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. 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). The small 4KB sectors allow for greater flexibility in applications that require data and parameter storage. The W25Q32BV has 1,024 erasable sectors and 64 erasable blocks respectively. 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). Up to 256 bytes can be programmed at a time. The W25Q32BV array is organized into 16,384 programmable pages of 256-bytes each. The device operates on a single 2.7V to 3.6V power supply with current consumption as low as 4mA active and 1♚ for power-down.
They are ideal for code shadowing to RAM, executing code directly from Dual/Quad SPI (XIP) and storing voice, text and data. The 25Q series offers flexibility and performance well beyond ordinary Serial Flash devices. The W25Q32BV (32M-bit) Serial Flash memory provides a storage solution for systems with limited space, pins and power.
