P24C64C-UNH-MIR 产品概述

一、产品简介

P24C64C-UNH-MIR 是普冉(PUYA)推出的一款 64Kbit 串行 EEPROM,采用 I2C 兼容接口,提供高可靠性与低功耗的非易失性数据存储解决方案。器件基于低功耗 CMOS 工艺设计,支持 1.7V 至 5.5V 宽工作电压范围,适用于多种电源环境。器件内部包含 8K x 8 位存储阵列,每页 32 字节,共 256 页,易于页写入与数据管理。

二、主要规格

  • 存储容量:64Kbit(8K x 8)
  • 接口类型:I2C 兼容,最高时钟频率 1MHz
  • 工作电压:1.7V ~ 5.5V
  • 工作温度:-40℃ ~ +85℃
  • 每页长度:32 字节(Page Write)
  • 写周期时间(Tw):典型 5ms(自定时写入)
  • 写周期寿命:1,000,000 次
  • 数据保留(TDR):100 年
  • 封装:DFN-8-EP (3x2)
  • 品牌:PUYA(普冉)

三、存储组织与操作特性

P24C64C 采用标准 I2C 双线接口(SDA、SCL),支持与主控器的简单串行通信,最高支持 1MHz 时钟,兼容常见单片机与微控制器。器件支持按页写入以提高写入效率,每次页面写入最多 32 字节;单字节写入也受支持。内部具有自定时写周期机制,主机发起写命令后无需额外时序管理,器件在内部完成写入并自动返回就绪状态。

四、可靠性与保护功能

器件采用高可靠性的非易失性存储单元设计,提供长达 100 年的数据保留能力与高达 100 万次的写入寿命,适合需要长期保存配置信息与校准数据的场景。硬件写保护功能可通过器件的写保护引脚实现对整个存储器的物理写入禁止,防止误写入或配置被篡改。此外,芯片集成噪声抑制功能,有助于在有电磁干扰或信号抖动的环境中提高通信稳定性与写入成功率。

五、典型应用

  • 工业控制与自动化设备:参数存储、配置项备份
  • 消费电子与便携设备:启动设置、校准数据保存
  • 通信与仪器仪表:设备识别信息与长期日志保存
  • 医疗与计量仪器:重要参数的非易失性保存

六、封装与选型建议

P24C64C-UNH-MIR 提供 DFN-8-EP(3x2) 紧凑封装,适合空间受限的 SMT 布局并有利于散热与焊接可靠性。选型时建议根据系统电源电压范围、工作温度与写入寿命需求确认器件型号;对需要防误写的系统建议外接写保护控制。使用 I2C 总线时注意总线拉高电阻与时钟频率的匹配以确保可靠通信。

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
