GD25LQ128EWIGR是北京兆易创新(Gigadevice)推出的一款128Mbit容量SPI NOR FLASH,针对低功耗、高速读写场景优化设计,适配1.65V~2.0V宽电压范围,采用小尺寸WSON-8-EP封装,以下从核心参数、性能优势、应用场景等维度详细概述。
该芯片的核心参数覆盖存储容量、接口、电压、速度及可靠性等关键维度,具体如下:
低电压低功耗适配
1.65V~2.0V的工作电压范围覆盖了大多数低功耗嵌入式系统的供电需求(如锂电池降压后电压、3.3V系统降压设计),无需额外升压/降压电路,简化系统硬件设计;35μA的待机电流可显著延长电池供电设备(如可穿戴、物联网终端)的续航时间。
高速读写能力
120MHz的SPI时钟频率高于行业常规80MHz水平,支持快速数据传输:页写入时间仅500μs,适合固件批量升级;32KB块擦除160ms,满足系统配置数据的快速更新需求,提升整体系统响应速度。
可靠耐用性
10万次擦写寿命是普通NOR FLASH(通常1万次)的10倍,适合频繁更新固件的场景(如智能音箱、路由器);20年数据保留时间确保存储信息长期有效,即使设备长期断电也能保持数据完整,降低数据丢失风险。
小尺寸封装设计
采用WSON-8-EP(5×6mm)封装,体积仅为常规SOP-8封装的1/3左右,适合高密度PCB布局(如可穿戴设备、小型物联网模块);暴露焊盘(EP)设计增强散热性能,降低芯片工作温度,进一步提升可靠性。
GD25LQ128EWIGR凭借低功耗、高速、可靠的特性,广泛适配以下场景:
北京兆易创新作为国内存储芯片龙头企业,GD25系列NOR FLASH已通过严格的可靠性测试(温度循环、湿度老化、ESD测试等),兼容性覆盖主流MCU(STM32、NXP Kinetis等)和MPU平台;同时提供完善的技术支持( datasheet、参考设计、样片申请),助力客户快速实现产品落地。
综上,GD25LQ128EWIGR是一款平衡低功耗、高速读写与可靠性的SPI NOR FLASH,适合大多数嵌入式系统的存储需求,尤其在物联网、消费电子等低功耗场景中具有显著优势。

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.
