GD25LQ16EEIGR是北京兆易创新推出的一款16Mbit(2MB)容量NOR FLASH存储器,专为低功耗、高速读写及宽温应用场景设计,具备SPI串行接口,可满足嵌入式系统、物联网终端等领域的存储需求。
该产品的核心参数覆盖存储、接口、性能及环境等关键维度,清晰适配多场景需求:
高速读写能力
133MHz高速SPI接口支持约16MB/s的典型读速度(133Mbps bit率换算),可满足嵌入式系统固件快速加载需求,提升设备启动及响应速度。
低功耗设计
待机电流仅10uA,远低于多数同容量NOR FLASH,尤其适合电池供电的物联网终端(如智能手环、传感器节点),有效延长设备续航时间。
小体积封装适配
提供SOP8、USON8等小封装形式,节省PCB布局空间,适配紧凑型设备设计(如蓝牙耳机、智能手表)。
指令集兼容性
兼容SPI标准指令集,与市场多数同规格NOR FLASH pin-to-pin兼容,便于系统替换升级,降低设计成本。
GD25LQ16EEIGR的性能特点使其适用于以下场景:
物联网终端设备
智能手环、智能家居传感器、无线蓝牙模块等低功耗设备,可存储配置参数、传感器日志及固件,满足长期续航需求。
工业控制模块
PLC、远程IO模块、工业传感器节点等,宽温范围(-40~85℃)适应户外及工业现场极端温度,10万次擦写寿命支持频繁数据更新。
消费电子配件
蓝牙耳机、智能音箱、智能门锁等,存储固件及用户配置(如蓝牙配对信息、音量设置),小封装适配设备小型化需求。
嵌入式系统固件存储
低电压MCU(如ARM Cortex-M0+/M3系列)的外部固件存储,16Mbit容量可容纳中等复杂度嵌入式程序,无需复杂内存扩展。
长擦写寿命
10万次擦写寿命远超多数同容量NOR FLASH(通常1万次),适合频繁更新数据的场景(如工业日志、物联网固件OTA升级)。
持久数据保留
20年数据保留时间确保断电后长期存储的数据(如设备配置、历史日志)不丢失,满足设备长期使用需求。
抗干扰设计
符合工业级EMC要求,可适应工业现场复杂电磁环境,避免数据传输错误或存储异常。
宽温度范围
-40℃~+85℃工业级温度范围,覆盖户外设备(如太阳能传感器)、冷库监控系统等极端温度场景,无需额外散热/保温设计。
低电压工作
1.65V~2.1V宽电压范围,直接匹配低电压MCU(如部分ARM Cortex-M低功耗版本),无需电平转换电路,简化系统设计并降低功耗。
综上,GD25LQ16EEIGR以16Mbit容量、133MHz高速SPI、低功耗及宽温适配为核心优势,可广泛应用于物联网、工业控制、消费电子等领域,是嵌入式系统存储方案的可靠选择。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
