16M-Bit Serial Flash Memory With Dual And Quad SPI

Winbond 

W25Q16BV

1. GENERAL DESCRIPTION

The W25Q16BV (16M-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 devices operate 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 W25Q16BV array is organized into 8,192 programmable pages of 256-bytes each. Up to 256 bytes

can be programmed at a time. 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 W25Q16BV has 512

erasable sectors and 32 erasable blocks respectively. The small 4KB sectors allow for greater flexibility in

applications that require data and parameter storage. (See figure 2.)

The W25Q16BV 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 for Dual Output and 416MHz for Quad Output when using the Fast

Read Dual/Quad Output 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 with a 64-bit Unique Serial Number.
