REVISION HISTORY (74)Publication Release Date: May 02, 2017- 4 - Revision D1. GENERAL DESCRIPTIONSThe 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.2.

PIN DESCRIPTIONS4.1 Chip Select (/CS)The SPI Chip Select (/CS) pin enables and disables device operation. When /CS is high the device is deselected and the Serial Data Output (DO, or IO0, IO1, IO2, IO3) pins are at high impedance. When deselected, the devices power consumption will be at standby levels unless an internal erase, program or write status register cycle is in progress. When /CS is brought low the device will be selected, power consumption will increase to active levels and instructions can be written to and data read from the device. After power-up, /CS must transition from high to low before a new instruction will be accepted. The /CS input must track the VCC supply level at power-up and power-down (see “Write Protection” and Figure 58). If needed a pull-up resister on the /CS pin can be used to accomplish this.4.2 Serial Data Input, Output and IOs (DI, DO and IO0, IO1, IO2, IO3)The W25Q128JV supports standard SPI, Dual SPI and Quad SPI operation. Standard SPI instructions use the unidirectional DI (input) pin to serially write instructions, addresses or data to the device on the rising edge of the Serial Clock (CLK) input pin. Standard SPI also uses the unidirectional DO (output) to read data or status from the device on the falling edge of CLK.Dual and Quad SPI instructions use the bidirectional IO pins to serially write instructions, addresses or data to the device on the rising edge of CLK and read data or status from the device on the falling edge of CLK. Quad SPI instructions require the non-volatile Quad Enable bit (QE) in Status Register-2 to be set. When QE=1, the /WP pin becomes IO2 and the /HOLD pin becomes IO3.4.3 Write Protect (/WP)The Write Protect (/WP) pin can be used to prevent the Status Register from being written. Used in conjunction with the Status Register’s Block Protect (CMP, SEC, TB, BP2, BP1 and BP0) bits and Status Register Protect (SRP) bits, a portion as small as a 4KB sector or the entire memory array can be hardware protected. The /WP pin is active low.4.4 HOLD (/HOLD)The /HOLD pin allows the device to be paused while it is actively selected. When /HOLD is brought low, while /CS is low, the DO pin will be at high impedance and signals on the DI and CLK pins will be ignored (don’t care). When /HOLD is brought high, device operation can resume. The /HOLD function can be useful when multiple devices are sharing the same SPI signals. The /HOLD pin is active low. When the QE bit of Status Register-2 is set for Quad I/O, the /HOLD pin function is not available since this pin is used for IO3. See Figure 1a-c for the pin configuration of Quad I/O operation.4.5 Serial Clock (CLK)The SPI Serial Clock Input (CLK) pin provides the timing for serial input and output operations. ("See SPI Operations")4.6 Reset (/RESET)A dedicated hardware /RESET pin is available on SOIC-16 and TFBGA packages. When it’s driven low for a minimum period of ~1µS, this device will terminate any external or internal operations and return to its power-on state.Note: Hardware /RESET pin is available on SOIC-16 or TFBGA; please contact Winbond for this package.- 9 -5. BLOCK DIAGRAMFigure 2. W25Q128JV Serial Flash Memory Block Diagram6.FUNCTIONAL DESCRIPTIONS6.1Standard SPI InstructionsThe W25Q128JV is accessed through an SPI compatible bus consisting of four signals: Serial Clock (CLK), Chip Select (/CS), Serial Data Input (DI) and Serial Data Output (DO). Standard SPI instructions use the DI input pin to serially write instructions, addresses or data to the device on the rising edge of CLK. The DO output pin is used to read data or status from the device on the falling edge of CLK.SPI bus operation Mode 0 (0,0) and 3 (1,1) are supported. The primary difference between Mode 0 and Mode 3 concerns the normal state of the CLK signal when the SPI bus master is in standby and data is not being transferred to the Serial Flash. For Mode 0, the CLK signal is normally low on the falling and rising edges of /CS. For Mode 3, the CLK signal is normally high on the falling and rising edges of /CS.6.2Dual SPI InstructionsThe W25Q128JV supports Dual SPI operation when using instructions such as “Fast Read Dual Output (3Bh)” and “Fast Read Dual I/O (BBh)”. These instructions allow data to be transferred to or from the device at two to three times the rate of ordinary Serial Flash devices. The Dual SPI Read instructions are ideal for quickly downloading code to RAM upon power-up (code-shadowing) or for executing non-speed-critical code directly from the SPI bus (XIP). When using Dual SPI instructions, the DI and DO pins become bidirectional I/O pins: IO0 and IO1.6.3Quad SPI InstructionsThe W25Q128JV supports Quad SPI operation when using instructions such as “Fast Read Quad Output (6Bh)”,and “Fast Read Quad I/O (EBh). These instructions allow data to be transferred to or from the device four to six times the rate of ordinary Serial Flash. When using Quad SPI instructions, the DI and DO pins become bidirectional IO0 and IO1, with the additional I/O pins: IO2, IO3.6.4Software Reset & Hardware /RESET pinThe W25Q128JV can be reset to the initial power-on state by a software Reset sequence. This sequence must include two consecutive instructions: Enable Reset (66h) & Reset (99h). If the instruction sequence is successfully accepted, the device will take approximately 30µS (t RST)to reset. No instruction will be accepted during the reset period. For the SOIC-16 and TFBGA packages, W25Q128JV provides a dedicated hardware /RESET pin. Drive the /RESET pin low for a minimum period of ~1µS (tRESET*) will interrupt any on-going external/internal operations and reset the device to its initial power-on state. Hardware /RESET pin has higher priority than other SPI input signals (/CS, CLK, IOs).Note:1.Hardware /RESET pin is available on SOIC-16 or TFBGA; please contact Winbond for his package.2.While a faster /RESET pulse (as short as a few hundred nanoseconds) will often reset the device, a 1us minimum isrecommended to ensure reliable operation.3.There is an internal pull-up resistor for the dedicated /RESET pin on the SOIC-16 and TFBGA-24 package. If the reset functionis not needed, this pin can be left floating in the system.6.5Write ProtectionApplications that use non-volatile memory must take into consideration the possibility of noise and other adverse system conditions that may compromise data integrity. To address this concern, the W25Q128JV provides several means to protect the data from inadvertent writes.6.5.1Write Protect Features∙Device resets when VCC is below threshold∙Time delay write disable after Power-up∙Write enable/disable instructions and automatic write disable after erase or program∙Software and Hardware (/WP pin) write protection using Status Registers∙Additional Individual Block/Sector Locks for array protection∙Write Protection using Power-down instruction∙Lock Down write protection for Status Register until the next power-up∙One Time Program (OTP) write protection for array and Security Registers using Status Register** Note:This feature is available upon special order. Please contact Winbond for details.Upon power-up or at power-down, the W25Q128JV will maintain a reset condition while VCC is below the threshold value of V WI, (See Power-up Timing and Voltage Levels and Figure 43). While reset, all operations are disabled and no instructions are recognized. During power-up and after the VCC voltage exceeds V WI, all program and erase related instructions are further disabled for a time delay of t PUW. This includes the Write Enable, Page Program, Sector Erase, Block Erase, Chip Erase and the Write Status Register instructions. Note that the chip select pin (/CS) must track the VCC supply level at power-up until the VCC-min level and t VSL time delay is reached, and it must also track the VCC supply level at power-down to prevent adverse command sequence. If needed a pull-up resister on /CS can be used to accomplish this.After power-up the device is automatically placed in a write-disabled state with the Status Register Write Enable Latch (WEL) set to a 0. A Write Enable instruction must be issued before a Page Program, Sector Erase, Block Erase, Chip Erase or Write Status Register instruction will be accepted. After completing a program, erase or write instruction the Write Enable Latch (WEL) is automatically cleared to a write-disabled state of 0.Software controlled write protection is facilitated using the Write Status Register instruction and setting the Status Register Protect (SRP, SRL) and Block Protect (CMP, TB, BP[3:0]) bits. These settings allow a portion or the entire memory array to be configured as read only. Used in conjunction with the Write Protect (/WP) pin, changes to the Status Register can be enabled or disabled under hardware control. See Status Register section for further information. Additionally, the Power-down instruction offers an extra level of write protection as all instructions are ignored except for the Release Power-down instruction.The W25Q128JV also provides another Write Protect method using the Individual Block Locks. Each 64KB block (except the top and bottom blocks, total of 126 blocks) and each 4KB sector within the top/bottom blocks (total of 32 sectors) are equipped with an Individual Block Lock bit. When the lock bit is 0, the corresponding sector or block can be erased or programmed; when the lock bit is set to 1, Erase or Program commands issued to the corresponding sector or block will be ignored. When the device is powered on, all Individual Block Lock bits will be 1, so the entire memory array is protected from Erase/Program. An “Individual Block Unlock (39h)” instruction must be issued to unlock any specific sector or block.The WPS bit in Status Register-3 is used to decide which Write Protect scheme should be used. When WPS=0 (factory default), the device will only utilize CMP, SEC, TB, BP[2:0] bits to protect specific areas of the array; when WPS=1, the device will utilize the Individual Block Locks for write protection.。

一辆混凝土罐车转弯时，地面突然塌陷，罐车四个车轮陷入塌陷处后倾倒，砸中路边两辆车；一幢只有20年历史的居民楼突遭粉碎性倒塌，事故造成一人死亡、六人受伤……近年来，随着地下渗水导致楼倒路陷等建筑安全事件的频发，一度被人忽视的建筑地下渗漏问题正愈发引起公众的关注。
而据中国建筑防水协会和北京零点市场调查与分析公司联合发布的《2013年全国建筑渗漏状况调查项目报告》，全国建筑地下渗漏率达到57.51%，个别城市渗透率甚至达到百分之百，我国建筑地下渗漏的现状不容乐观。
楼倒地陷事故累累
近年来频频发生的地面塌陷、楼房倾斜倒塌事件，在很大程度上，与建筑地下长期渗漏有重要关联。
2014年9月，北京市大兴区西红门南桥附近，一辆混凝土罐车转弯时，地面突然塌陷，罐车四个车轮陷入塌陷处后倾倒，砸中路边两辆车，幸无人员伤亡。
据现场工人介绍，该处由于绿化带内电信井渗水，渗入路床内导致基层泥土被涮空，路面下出现一直径约2米的空洞，造成最后的塌陷。
另据公开报道，2014年4月4日，浙江奉化一幢只有20年历史的居民楼突遭粉碎性倒塌，事故造成一人死亡、六人受伤，伤者中一名年轻的女孩惨遭截肢。
此前，倒塌的楼房曾获评样板工程。
事件发生后，技术人员对周边7幢房屋进行质量检测。
在挖开地基时，其中两处仅下挖半米深即冒出大量地下水，工作人员用一台抽水机持续作业都无法抽光。
事后专家分析认为，事故发生原因在于地下防水工程不合格，导致地下长期渗漏，进而引发钢筋锈蚀、混凝土劣化、建筑地下结构形态发生改变等一系列问题。
数据显示，我国每年新增大约20亿平方米的建筑总量，超过全球年建筑总量50%以上，是每年新建建筑量最大的国家，然而这些建筑的寿命却很少能达到设计年限。
“影响建筑寿命的因素很多，包括城市规划的原因，但其中肯定有地下渗漏的问题，如此大的建筑体量，如果不能把好建筑安全这一关，将埋下重大的安全隐患。
”全国政协常委、九三学社中央副主席赖明如是表示。
地下结构存在先天缺陷
结构主体防水没做好，附着在上面的防水层做得再好，也无法避免地下渗漏问题，因为再好的防水材料也不可能保障建筑设计寿命。
记者走访北京及周边多个正在施工的工程项目，在问及现场施工人员该建筑是否做防水处理时，多数项目负责人表示已经做过，有的项目负责人还向记者强调，他们的工程用的是市面上最好的防水材料。
业内防水专家、北京龙阳伟业科技有限公司董事长王伟表示，目前人们对于建筑地下防水的认识走入误区，忽视了结构自防水的主导作用。
地下渗漏在于地下结构存有“先天缺陷”，另外，随着时间推移，有害物质将借助于渗漏水，对本就存在隐患的建筑地下结构造成“后天伤害”，最终将会缩短建筑寿命，也会直接威胁建筑安全。
“结构主体防水没做好，附着在上面的防水层做得再好，也无法避免地下渗漏问题，因为再好的防水材料也不可能保障建筑设计寿命。
”
北京市政府专业顾问、2008奥运工程指挥部领衔专家杨嗣信教授指出，目前建筑地下防水过分依赖“防水材料”的思想已成惯性，造成建筑地下结构的许多问题被忽视和遮蔽，而地下结构设计和管理上的缺陷，是任何防水材料都无法弥补的，“防水材料”不过是建筑结构问题的遮羞布。
事实上，地下工程的混凝土不仅要具有结构功能和安全，同时也要有防水密实的功能。
然而当前我国“结构问题”被忽视，将大量精力专注于地下工程的“材料防水层”，而防水材料寿命也不过只有二三十年，与建筑百年寿命的预期相差甚远。
而按目前相关标准，建筑地下防水保修期仅5年。
建筑地下防水与建筑寿命不匹配的矛盾突出，直接影响建筑安全。
防水工程成摆设
一些地方开发商有个特点，在建筑工程上重造型、重外表，而不重视内在质量好不好，这种思维直接导致在工程中装修的价钱提得很高，而地下工程费用却捉襟见肘。
北京城建科技促进会常务副理事长王建明在接受记者采访时表示，现在在施工过程中，很多人简单凑合地把防水做完，费用压得很低，漏了再堵。
另外，还有一种现象，施工方觉得反正是漏水，干脆就不做防水，漏了以后再去堵、再去修。
实际上大家只是把防水作为功能问题，没有把防水的渗漏问题上升到影响质量安全的高度。
王伟认为，要解决我国地下工程安全问题，首先需要改变的是观念。
“人们过度追求速度、追求利润，不可避免地降低建筑质量标准，忽视建筑质量与建筑安全。
特别是对建筑地下结构隐蔽性工程问题进行遮盖或隐藏的思维方式以及急功近利、忽视质量的价值取向，是导致我国建筑质量普遍较差、建筑寿命过短、建筑安全隐患日益严重的根本原因。
”地下渗漏后患无穷
据统计，我国目前现有400亿平方米的既有建筑，每年新增总量约20亿平方米。
但同时，我国建筑地下渗漏现象与日俱增，“三高现象”凸显。
防水材料生产和施工技术水平越
来越高，建筑地下防水验收合格率越来越高，而建筑地下渗漏率却越来越高，“三高痼疾”长期困扰我国建筑业质量水平的提高，建筑地下渗漏严重影响建筑寿命，威胁建筑安全。
王伟表示，造成这种困境的原因是当前我国大量应用于地下工程防水的“防水层”，其材料寿命最多不过20余年，应用在工程中，实际寿命更短，与建筑百年寿命的预期相差甚远。
按相关标准，建筑地下防水工程保修期仅5年，与建筑结构寿命不匹配的矛盾十分突出。
王伟指出，防水行业是建筑业最底层最末端的一环，处在被忽视、漠视的边缘。
正因如此，近年楼价翻番，装修的投入也在不断增加，但建筑防水造价却在低位运行，行业内偷工减料、以次充好的现象大行其道。
“更可怕的是，现在没人重视建筑地下渗漏对建筑安全的危害，如果当前不解决这一问题，未来会埋下很大的安全隐患。
