Winbond 25Q16B 16Mbit Serial Flash Memory With Dual and Quad SPI
Availability: In stock
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 1μAfor 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 byte scan be programmed at a time. Pages can be erased in groups of 16 (sector erase), groups of 128 (32KBblock erase), groups of 256 (64KB block erase) or the entire chip (chip erase). The W25Q16BV has 512erasable sectors and 32 erasable blocks respectively. The small 4KB sectors allow for greater flexibility in applications that require data and parameter storage. 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 and16-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.
