W25Q16DVSSIG中文资料资料

W25Q16DVSSIG阵列被组织成8192个可编程的256字节的每一页。最多256个字节可以被编程一次。页面可以被删除16组（4KB扇区擦除），组128（32KB的块擦除），组256（64KB块擦除）或整个芯片（芯片擦除）。有512的w25q16dv擦除部门和32个可擦除块分别。小4KB扇区允许更大的灵活性，在应用中需要的数据和参数存储。（见图2。）的w25q16dv支持标准的串行外设接口（SPI），和一个高性能的双/四输出以及双/四：I/OSPI串行时钟，芯片选择，串行数据I/O0（DI），I/O1（做），我/O2（/可湿性粉剂），和我/O3（保持）。到104mhzSPI的时钟频率的支持允许208mhz等效时钟频率（104mhz×2）双I/O416mhz（104mhz×4）四I/O当使用快速读取双/四I/O指令。这些传输率可以比标准的异步8和16位并行闪存。连续读模式允许作为指令开销读取一个24位的地址8-clocks一些高效的内存访问，让真正的XIP（执行）的操作。一个针，写保护引脚可编程写保护，在顶部或底部的阵列控制，提供进一步的控制灵活性。此外，该设备支持JEDEC标准的制造商和一个64位的唯一的序列号识别设备。

The W25Q16DVSSIG (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 device operates on a SINGLE 2.7V to 3.6V power supply with current consumption as low as 4mA ACTIVE and 1|ìA for power-down.

The W25Q16DV array is organized into 8,192 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 W25Q16DV has 512 erasable sectors and 32 erasable blocks respectively. The small 4KB sectors allow for greater flexibility in applications that require data and parameter storage. (See figure 2.) The W25Q16DV 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 (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 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 identification with a 64-bit Unique Serial Number.
