W25Q128JVSIQ 是 Winbond Electronics 的 128M 位(16M 字节)串行 NOR 闪存设备,采用 8 引脚 SOIC 208-mil 封装。它属于 SpiFlash 系列,支持标准 SPI、双 SPI 和四 SPI 接口,可为代码存储、数据记录和就地执行 (XIP) 应用提供灵活、高速的数据访问。.

存储器阵列分为 65,536 个可编程页,每个页 256 字节。该器件支持灵活的擦除粒度:4 KB 扇区(共 4,096 个)、32 KB 块、64 KB 块(共 256 个)和全芯片擦除。页面编程时间一般为 3 毫秒,32 KB 块的块擦除时间约为 120 毫秒。.

SPI 时钟频率支持高达 133 MHz,在双 I/O 模式下可实现 266 MHz 的等效数据传输速率,在四 I/O 模式下可实现 532 MHz 的等效数据传输速率。在 133 MHz 的四路 SPI 模式下,有效数据吞吐量可达 66 MB/s,超过了许多并行闪存。该器件还支持 SPI 模式 0(CPOL=0,CPHA=0)和模式 3(CPOL=1,CPHA=1)。.

工作电压范围为 2.7V 至 3.6V,与标准 3.3V 逻辑系统兼容。133 MHz 时的有效读取电流通常为 25 mA。待机电流通常为 15 uA,掉电电流降至 1 uA 以下,因此该器件适合电池供电应用。.

安全功能包括:软件和硬件写保护、开机/关机数据保护、用于扇区保护的易失性和非易失性锁定位、256 字节一次性可编程(OTP)安全寄存器、用于设备识别的唯一 64 位序列号,以及用于用户数据存储的三个 256 字节安全寄存器。串行闪存可检测参数(SFDP)寄存器便于软件自动检测和配置。.

该器件支持程序/擦除暂停和恢复操作,允许中断长时间擦除操作,以进行优先级更高的读取。连续读取模式支持 8、16、32 和 64 字节的可配置包络长度,以优化高速缓存。.

W25Q128JVSIQ 每个扇区可进行 100,000 次编程/擦除循环,数据保存期为 20 年。工作温度范围为 -40C 至 +85C(工业级)。该器件符合 RoHS3 标准、MSL 3 级(168 小时),并被归类为 ECCN 3A991B1A。标准管式包装。.

JV 变体是 W25Q128 系列的最新一代产品,与早期的 JQ 和 JM 变体相比,具有增强的 SPI 模式和更高的性能。后缀 SIQ 表示 SOIC-8 封装、工业温度范围和管式封装。.

W25Q128JVSIQ 作为串行 NOR 闪存运行,通过主机微控制器或 SoC 发出的 SPI 兼容命令序列进行控制。.

内存结构:128M 位(16M 字节)阵列采用从 000000h 到 FFFFFFh 的平面地址空间(24 位寻址)。阵列按层次划分为每页 256 字节(共 65,536 页),每 4 KB 扇区 16 页(共 4,096 扇区),每 64 KB 块 256 页(共 256 块)。这种分层结构允许灵活的擦除粒度:单个 4 KB 扇区可独立擦除,而较大的块或整个芯片可进行批量擦除操作。.

SPI 命令协议:主机通过低电平 /CS 与设备通信,在 DI (IO0) 上时钟输入 8 位命令操作码,然后根据特定命令的要求输入地址字节和数据字节。数据在 CLK 上升沿移入,在 CLK 下降沿移出。每个命令序列都以高电平/CS 除断而结束。标准读取命令使用 DI 进行数据输入,使用 DO 进行数据输出。在双通道 SPI 模式下,IO0 和 IO1 都是双向数据线。在四 SPI 模式下,所有四条 IO 线(IO0-IO3)同时传输数据,吞吐量翻了两番。.

写入操作:在写入数据之前,必须先擦除目标内存区域(所有位均置 1)。页面编程命令(02h)可在单页边界内写入多达 256 字节的数据。跨页边界写入的数据会缠绕到同一页的开头,因此需要对较大的数据集进行多次页编程操作。在进行任何编程或擦除操作前,必须发出写入启用命令 (06h)。在设备接受写入命令之前,必须设置状态寄存器 WEL(写入启用锁存器)位。.

擦除操作:提供四种擦除命令:扇区擦除 (20h, 4KB)、32KB 块擦除 (52h)、64KB 块擦除 (D8h) 和芯片擦除 (C7h/60h)。擦除操作将目标区域的所有位设置为 1(逻辑高电平)。典型的擦除时间为:扇区擦除 45 毫秒(最长 200 毫秒),32 KB 块擦除 120 毫秒,64 KB 块擦除 150 毫秒,芯片擦除 40 秒(最长 200 秒)。.

暂停/恢复:程序/擦除暂停命令(75h)允许中断正在进行的程序或擦除操作,以便从内存的不同区域读取数据。恢复编程/擦除命令(7Ah)可重新启动暂停的操作。该功能可在长时间擦除周期内实现实时数据访问。.

保护机制:写保护通过状态寄存器位和锁定机制进行控制。/WP 引脚(IO2)可用于对状态寄存器进行硬件保护,防止意外更改保护设置。单个扇区保护可通过状态寄存器中的块保护位(BP3-BP0)来实现。一旦设置,扇区锁定功能可永久防止修改选定扇区的保护设置。.

电源管理:该器件支持通过命令 B9h 进入深度掉电模式,将电流消耗降至 1 uA 以下。从掉电模式退出需要执行 "从深度掉电模式释放 "命令 (ABh),然后至少延迟 3 秒。上电期间,器件自动进入待机模式,/CS 必须在上电斜坡期间保持高电平,以防止出现虚假命令。.
