W25Q80DV集成電路（IC）的存儲器規(guī)格書PDF中文資料

1. GENERAL DESCRIPTION

The W25Q80DV/DL (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 W25Q80DV operates on a single 2.7V to 3.6V and the

W25Q80DL operateds on a single 2.3V to 3.6V power supply with current consumption as low as 1μA

for power-down.

The W25Q80DV/DL 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/DL 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.
