P24C512-SSH-MIR 产品概述

一、产品简介

P24C512-SSH-MIR 是普冉(PUYA)推出的一款高可靠性、低功耗的串行 EEPROM 存储器,容量为 512‑Kbit(等同于 64K × 8 位),每页 128 字节,采用标准 I2C 接口,兼容工业级温度与电压范围,适用于对数据保持性和写入耐久性有较高要求的嵌入式系统与工业设备。

二、主要规格

  • 存储容量:512 Kbit(64K × 8)
  • 页大小:128 字节/页
  • 接口类型:I2C(支持最高时钟频率 fc = 1 MHz,Fast-mode Plus)
  • 工作电压:1.7 V ~ 5.5 V
  • 工作温度:-40 ℃ ~ +125 ℃
  • 写周期时间(Tw):典型 5 ms(字节/页写入完成时间)
  • 数据保持(TDR):100 年
  • 写周期寿命:1,000,000 次
  • 封装:SOP‑8
  • 品牌:PUYA(普冉)

三、关键特性

  • 页写保护功能:支持以页为单位的写入与保护策略,减少不必要的写磨损并提高数据安全性。
  • 噪声抑制:内部输入滤波/噪声抑制设计,增强总线抗干扰能力,利于工业环境稳定通信。
  • 硬件写保护:提供 WP 引脚(SOP‑8 封装中可用),可通过硬件信号防止误写入。
  • I2C 兼容:支持标准 I2C 时序与协议,主机可通过 7-bit 地址与 16-bit 内部地址进行寻址(适用于 64K 字节空间)。
  • 宽电压与温度范围:兼容低功耗与工业级供电/环境要求,适用于多种电源方案与恶劣工作环境。

四、典型应用

  • 工业控制与数据记录:参数存储、历史记录、配置项保存。
  • 汽车电子(在允许的车规系统中):需注意整车认证与 EMC 要求。
  • 智能计量与楼宇设备:长期数据保持性强,适合计量设备参数及校准数据存储。
  • 消费电子与嵌入式系统:固件参数、序列号、标定数据等非易失性存储。
  • 引导代码/配置备份:用于存储小容量固件片段或启动配置。

五、设计与使用建议

  • 总线电阻:1 MHz 工作时建议使用较小阻值上拉电阻(常用 2.2 kΩ ~ 4.7 kΩ),以满足上升时间要求;较低速率可采用 10 kΩ。
  • 写入策略:尽量采用页写(最多 128 字节)以提高吞吐与减少写次数;写操作完成后需等待 Tw(约 5 ms)或使用 ACK Polling 确认写完成。
  • 电源与滤波:在 VCC 近端放置 0.1 μF 旁路电容以抑制瞬态噪声;保持 SDA/SCL 总线电容尽量低以保障高速通信。
  • 引脚与保护:若需永久只读,可将 WP 引脚拉低或高(根据产品手册),并在 PCB 布局阶段预留焊跳线以便调试与生产测试。
  • EMC 与隔离:在工业或汽车应用中需注意总线滤波与共模抑制,避免长线干扰导致通信错误。

六、封装与订购信息

  • 型号:P24C512-SSH-MIR
  • 品牌:PUYA(普冉)
  • 封装:SOP‑8(工业级)
  • 备注:在选型与部署前,建议参考厂商完整数据手册获取引脚定义、时序图、写保护逻辑与温度漂移等详细电气参数,并与供应商确认量产与可靠性测试标准。

如需引脚分配、时序图或与 MCU/I2C 总线的典型连接电路图,我可以进一步提供参考设计与布局建议。

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
