ZD24C256A-SSGMB是澜智(Zetta)推出的一款256Kbit非易失性串行EEPROM,主打工业级可靠性与宽适配性,采用I2C高速接口设计,可满足消费电子、工业控制、车载电子等多领域的配置存储需求。作为无需持续供电即可长期保留数据的器件,它支持字节级写入与随机读取,能直接对接主流MCU/MPU的I2C接口,简化硬件设计。
存储容量为256Kbit(即32KB),采用标准I2C串行接口,支持1MHz高速时钟频率——比传统I2C标准模式(100kHz)快10倍,可大幅提升批量数据传输效率(如一次写入64字节页数据仅需约0.6ms)。
支持1.7V~5.5V供电,覆盖从低功耗1.8V MCU(如STM32L系列)到传统5V系统的全场景,无需额外电平转换电路,适配新旧设备的硬件升级需求。
采用SOIC-8表面贴装封装,体积小巧(与DIP-8引脚布局兼容),适合高密度PCB设计;引脚定义符合I2C EEPROM标准:
无需额外布线调整,可直接对接主流MCU的I2C接口。
支持**-40℃~+85℃工业级温度范围**,可适应户外传感器、车载电子等极端温度场景(如北方冬季-30℃、南方夏季车内+60℃)。
内置ESD防护(符合IEC 61000-4-2标准),可抵抗静电干扰;写保护功能可通过WP引脚硬件使能,避免意外擦写导致的系统故障。
澜智(Zetta)作为专注存储器件的品牌,ZD24C256A-SSGMB经过严格的高低温循环测试、寿命测试与ESD测试,符合RoHS环保标准,可提供稳定可靠的存储性能,适用于对可靠性要求较高的工业与消费电子场景。
该产品以高性价比、宽适配性与长寿命为核心优势,可有效解决各类设备的非易失性存储需求。

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.
