P24C128D-SSH-MIR是普冉半导体(PUYA)推出的一款工业级I2C接口EEPROM,主打「高可靠性、宽电压适配、快速读写」三大核心优势,专为需要长期稳定存储小容量数据的嵌入式场景设计。作为128Kbit(16KB)容量的非易失性存储器,它可在无电源状态下永久保留数据,同时支持低功耗运行,适配从智能穿戴到工业控制的多类设备需求。
存储容量为128Kbit(即16384字节),采用「字节/页可写+随机地址访问」设计,支持单次读写任意位置数据,无需按块操作,适合存储传感器校准参数、设备配置信息等小批量数据。
采用I2C两线制串行接口,支持「1MHz快速模式时钟频率」,兼容I2C标准模式(100kHz)与快速模式,可直接对接主流MCU(如STM32、ATmega系列),无需额外电平转换。通过A0-A2地址脚可配置7位设备地址,最多支持8个同型号器件级联在同一总线,简化系统布线。
采用SOP-8表面贴装封装,尺寸紧凑(约5.2mm×6.0mm),适合高密度PCB布局。引脚定义清晰:
相比同类产品,P24C128D-SSH-MIR核心优势突出:
该产品是嵌入式系统中小容量非易失存储的高性价比选择,可满足多行业的稳定存储需求。

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.
