GENERAL DESCRIPTION

The W25Q64CV (64M-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 W25Q64CV array is organized into organized into 32,768 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 W25Q64CV has 2.048 erasable sectors and 128 erasable blocks respectively. The small 4KB sectors allow for greater flexibility in application require data and parameter storage. (See figure 2.)

The W25Q64CV 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, 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 (80MHz * 2) for Dual I/O and 320MHz (80MH * 4) for Quad I/O when using the Fast Read Dual/Quad I/O instructions. These transfer rates can outperform standard Asynchronous 8 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.
