W25Q16CV
1. GENERAL DESCRIPTION
The W25Q16CV (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 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 W25Q16CV 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 (4KB sector erase), groups of 128
(32KB block erase), groups of 256 (64KB block erase) or the entire chip (chip erase). The W25Q16CV
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 W25Q16CV 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. 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.
