P24C128D-TSH-MIR 产品概述

一、产品简介

P24C128D-TSH-MIR(品牌:PUYA/普冉)是一款128-Kbit (16384 x 8) 的I2C兼容串行EEPROM,采用低功耗CMOS工艺,封装为TSSOP-8。器件支持高达1MHz的I2C时钟频率,单页64字节的页写操作,适用于需高可靠性存储少量非易失性数据的系统。

二、主要规格与特性

  • 存储容量:128 Kbit(16384 x 8);页大小:64 字节
  • 接口类型:I2C(最高时钟频率 fc = 1MHz)
  • 工作电压:1.7 V ~ 5.5 V(宽电压范围,适配多种系统电源)
  • 工作温度:-40 ℃ ~ +85 ℃
  • 读/写电流:读操作典型 400 μA,写操作典型 1.6 mA(低功耗设计)
  • 写周期时间(自定时):最大 Tw = 5 ms
  • 数据保留:TDR ≥ 100 年
  • 擦写/写入寿命:≥ 1,000,000 次
  • 功能特性:硬件写保护、噪声抑制、顺序/随机读取、页写与部分页写支持

三、功能亮点

  1. 硬件写保护:提供外部写保护机制,防止意外写入或软件故障导致的数据破坏。
  2. 噪声抑制:内置噪声抑制功能,提高总线可靠性和读写稳定性,适合工业类干扰环境。
  3. 页写与部分页写:支持最多64字节的页写,可在单次写周期内高效编程;允许部分页写以减少总线传输与功耗。
  4. 顺序与随机读取:支持从任意地址随机读取或连续顺序读取,便于批量数据获取与流式读取。

四、应用场景

  • 工业控制与传感器节点:非易失性配置参数、校准常数存储
  • 家用及消费电子:固件参数、用户设定、计数器保存
  • 医疗和通信设备:要求长寿命、高可靠性的小容量数据保存
  • 智能卡/计量设备:抗干扰要求高且需写保护的存储应用

五、封装与选型建议

  • 封装:TSSOP-8,便于表面贴装(SMT)组装与散热。
  • 选型提示:若系统存在较强电磁干扰或总线抖动,建议启用器件噪声抑制功能并合理设计I2C线路终端;对关键数据使用外部写保护引脚以及系统级备份策略以保证更高可靠性。

六、典型使用注意事项

  • 写操作为自定时,写入后应在下一次总线访问前等待最大 Tw(5 ms)或通过器件的ACK检测确认完成。
  • 页写跨页操作时,仅在单页边界内写入有效,跨页写入会回绕覆盖起始页地址。
  • 长期存储和频繁写入场景应考虑寿命预算(1,000,000 次写周期)与数据保留(≥100 年)匹配。

P24C128D-TSH-MIR在性能、可靠性与低功耗之间取得平衡,适合需要稳定非易失性存储且工作环境复杂的各种嵌入式与工业应用。若需详细电气特性曲线、时序图或参考电路,请告知具体需求以便提供更详尽资料。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
