GENERAL DESCRIPTION
The W25Q80DV (8M-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 1µA for power-down. All
devices are offered in space-saving packages.
The W25Q80DV array is organized into 4,096 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 W25Q80DV has 256 erasable sectors and 16
erasable blocks respectively. The small 4KB sectors allow for
greater flexibility in applications that require data and parameter
storage. (See figure 2.)
The W25Q80DV 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 416MHz (104MHz 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. A Hold pin, Write Protect pin and programmable
write protection, with top, bottom or complement array control,
provide further control flexibility. Additionally, the device
supports JEDEC standard manufacturer and device identification with
a 64-bit Unique Serial Number.
