Circuit Board Chip 133Mhz 64M BIT W25Q64JVSSIQ Spi Flash with Dual,
Qual SPI & QPI
GENERAL DESCRIPTIONS
The W25Q64JV (64M-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 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 W25Q64JV array is organized into 32,768 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 W25Q64JV has 2,048 erasable sectors and 128 erasable blocks
respectively. The small 4KB sectors allow for greater flexibility
in applications that require data and parameter storage. (See
Figure 2.) The W25Q64JV 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 W25Q64JV 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 a 64-bit Unique Serial Number and three 256-bytes
Security Registers..
