GENERAL DESCRIPTION
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 5mA active and 1µA for power-down. All devices are offered in space-saving packages. The W25Q80/16/32 array is organized into 4,096/8,192/16,384 programmable pages of 256-bytes each. Up to 256 bytes can be programmed at a time using the Page Program instructions. 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 W25Q80/16/32 has 256/512/1024 erasable sectors and 16/32/64 erasable blocks respectively. The small 4KB sectors allow for greater flexibility in applications that require data and parameter storage. (See figure 2.) The W25Q80/16/32 supports the standard Serial Peripheral Interface (SPI), and a high performance Dual/Quad output as well as Dual/Quad I/O SPI using SPI pins: Serial Clock, Chip Select, Serial Data I/O0 (DI), I/O1 (DO), I/O2 (/WP), and I/O3 (/HOLD).
