۱۲۸M-bit Serial Flash Memory with uniform 4KB sectors and Dual/Quad SPI and QPI

حافظه spi flash با ظرفیت ۱۶مگابایت

۳V 128M-BIT

The W25Q128FV (128M-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. All devices are offered in spacesaving packages.
The W25Q128FV array is organized into 65,536 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
۱۲۸ (۳۲KB block erase), groups of 256 (64KB block erase) or the entire chip (chip erase). The
W25Q128FV has 4,096 erasable sectors and 256 erasable blocks respectively. The small 4KB sectors
allow for greater flexibility in applications that require data and parameter storage. (See Figure 2.)
The W25Q128FV support the standard Serial Peripheral Interface (SPI), Dual/Quad I/O SPI as well as
۲-clocks instruction cycle Quad Peripheral Interface (QPI): 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 and QPI 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 ID and SFDP Register, a 64-bit Unique Serial Number and three 256-bytes Security Registers.
