The W25Q128JV (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 1µA for power-down. All
devices are offered in space-saving packages.
The W25Q128JV 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 128
(32KB block erase), groups of 256 (64KB block erase) or the entire
chip (chip erase). The W25Q128JV 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 W25Q128JV supports the standard Serial Peripheral Interface
(SPI), Dual/Quad I/O SPI: Serial Clock, Chip Select, Serial Data
I/O0 (DI), I/O1 (DO), I/O2 and I/O3. SPI clock frequencies of
W25Q128JV of up to 133MHz are supported allowing equivalent clock
rates of 266MHz (133MHz x 2) for Dual I/O and 532MHz (133MHz x 4)
for Quad I/O when using the Fast Read Dual/Quad I/O. These transfer
rates can outperform standard Asynchronous 8 and 16-bit Parallel
Flash memories.
Additionally, the device supports JEDEC standard manufacturer and
device ID and SFDP, and a 64-bit Unique Serial Number and three
256-bytes Security Registers.
