W25N01GVZEIG
The W25N01GV (1G-bit) Serial SLC NAND Flash Memory provides a storage solution for systems with limited space, pins and power. The W25N SpiFlash family incorporates the popular SPI interface and the traditional large NAND non-volatile memory space. 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 25mA active and 10µA for standby. All W25N SpiFlash family devices are offered in space-saving packages which were impossible to use in the past for the typical NAND flash memory. The W25N01GV 1G-bit memory array is organized into 65,536 programmable pages of 2,048-bytes each. The entire page can be programmed at one time using the data from the 2,048-Byte internal buffer. Pages can be erased in groups of 64 (128KB block erase). The W25N01GV has 1,024 erasable blocks. The W25N01GV 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 (/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. The W25N01GV provides a new Continuous Read Mode that allows for efficient access to the entire memory array with a single Read command. This feature is ideal for code shadowing applications. A Hold pin, Write Protect pin and programmable write protection, provide further control flexibility. Additionally, the device supports JEDEC standard manufacturer and device ID, one 2,048-Byte Unique ID page, one 2,048-Byte parameter page and ten 2,048-Byte OTP pages. To provide better NAND flash memory manageability, user configurable internal ECC, bad block management are also available in W25N01GV.
W25N01GV(1G位)串行SLC NAND闪存为具有
有限的空间、引脚和电源。W25N SpiFlash系列集成了流行的SPI接口和
传统的大NAND非易失性存储器空间。它们非常适合将代码隐藏到RAM,执行
直接来自双/四路SPI(XIP)的代码,并存储语音、文本和数据。该设备在单个设备上运行
2.7V至3.6V电源,有源功耗低至25mA,备用功耗低至10µA。所有W25N
SpiFlash系列设备采用节省空间的封装,在过去是不可能使用的
典型的NAND闪存。
W25N01GV 1G位存储器阵列被组织成65536个可编程页面,每个页面2048字节。
使用来自2048字节内部缓冲器的数据,可以一次对整个页面进行编程。页
可以以64个为一组的方式擦除(128KB块擦除)。W25N01GV具有1024个可擦除块。
W25N01GV支持标准串行外围接口(SPI)、双/四路I/O SPI:串行时钟、,
芯片选择、串行数据I/O 0(DI)、I/O 1(DO)、I/O 2(/WP)和I/O 3(/HOLD)。SPI时钟频率高达
支持104MHz,允许双I/O和416MHz的等效时钟速率为208MHz(104MHz x 2)
使用快速读取双/四路I/O指令时,用于四路I/O(104MHz x 4)。
W25N01GV提供了一种新的连续读取模式,可有效访问整个
具有单个读取命令的内存阵列。此功能非常适合代码阴影应用程序。
保持引脚、写入保护引脚和可编程写入保护,提供了进一步的控制灵活性。
此外,该设备支持JEDEC标准制造商和设备ID,一个2048字节的唯一ID
页面、一个2048字节参数页面和十个2048字节OTP页面。提供更好的NAND闪存
内存可管理性、用户可配置的内部ECC、坏块管理也可在W25N01GV。
