GENERAL DESCRIPTIONS
The W25Q64FV (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.
All devices are offered in space-saving packages.
The W25Q64FV array is 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 W25Q64FV has 2,048 erasable sectors and 128
erasable blocks respectively. The small 4KB sectors allow for
greater flexibility in applications that require data and parameter
storage.
The W25Q64FV support the standard Serial Peripheral Interface
(SPI), Dual/Quad I/O SPI as well as 2- clocks instruction cycle
Quad Peripheral Interface (QPI): 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 416MHz (104MHz x 4)
for Quad I/O when using the Fast Read Dual/Quad I/O and QPI
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, a 64-bit Unique Serial
Number and three 256-bytes Security Registers.
