Winbond 25Q80B 8MBit Serial Flash Memory with Dual and Quad SPI
Availability: In stock
The W25Q80BV(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 3.6Vpower supply with current consumption as low as 4mA active and 1μA for power-down.The W25Q80BV array is organized into 4,096 programmable pages of 256-bytes each. Up to 256 byte scan be programmed at a time. Pages can be erased in groups of 16 (4KBsector erase),groups of 128(32KB block erase), groups of 256 (64KBblock erase) or the entire chip (chip erase). TheW25Q80BV has 256 erasable sectors and16erasable blocks respectively. The small 4KB sectors allow for greater flexibility in applications that require data and parameter storage. (See figure 2.)The W25Q80BV supports the standard Serial Peripheral Interface (SPI), and a high performance Dual/Quad output as well as Dual/Quad I/OSPI: Serial Clock, Chip Select, Serial Data I/O0 (DI), I/O1(DO), I/O2 (/WP), and I/O 3 (/HOLD). SPI clock frequencies of up to104MHz are supported allowing equivalent clock rates of 208MHz(104MHz x 2)for Dual I/O and 416MHz(104MHz x4)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, bottom or complement array control, provide further control flexibility. Additionally, the device supports JEDEC standard manufacture rand device identification with a 64-bit Unique Serial Number.
