M95640-DRDW8TP/K SPI EEPROM 产品概述

一、产品基本身份与定位

M95640-DRDW8TP/K是意法半导体(ST) 推出的串行电可擦除可编程只读存储器(EEPROM),属于工业级宽温系列核心产品。其定位为小容量、高可靠、高速SPI接口的非易失性存储方案,专为需要长期保存配置参数、状态数据且对环境适应性要求苛刻的电子系统设计,可覆盖工业控制、消费电子、物联网等多领域应用。

二、关键技术参数深度解析

2.1 存储容量与寻址

产品总容量为64Kbit(换算为8KByte),采用字节级寻址方式,可灵活存储设备校准系数、用户参数、状态阈值等小容量信息,无需占用过多硬件资源,适配对存储容量需求精准的场景。

2.2 接口与通信性能

  • 接口类型:标准SPI(串行外设接口),支持协议模式0/3,兼容性覆盖主流MCU/MPU;
  • 时钟频率:最高可达20MHz,支持高速数据读写,满足实时系统对存储响应速度的需求;
  • 引脚精简:仅需4根核心通信引脚(SCK、MOSI、MISO、CS),配合电源与地共8个引脚,简化电路设计与PCB布局。

2.3 电气与可靠性参数

  • 工作电压范围:1.7V~5.5V,覆盖低功耗系统(如1.8V电池供电设备)到常规5V系统,无需额外电平转换电路,降低BOM成本;
  • 写周期特性:单字节写周期时间为4ms,支持页写模式(最大页大小32字节),批量数据写入效率提升显著;
  • 寿命与数据保留:写周期寿命达400万次,可满足频繁参数更新的应用场景;数据保留时间为50年(25℃环境下),确保长期存储数据不丢失;
  • 擦除灵活性:无需整体擦除,支持字节/页级擦除,操作更精准高效。

2.4 环境适应性

  • 工作温度范围:-40℃~+105℃,符合工业级温度标准,可适应户外、 harsh工业环境(如工厂车间、户外传感器节点);
  • 存储温度:常规为-65℃~+150℃,进一步提升极端环境下的存储稳定性。

三、封装与引脚配置

产品采用8-TSSOP(薄型小尺寸封装),尺寸仅为3mm×4.9mm,适合紧凑型PCB设计。引脚功能如下(参考ST标准定义):

引脚号 功能 说明 1 CS 片选(低电平有效) 2 SO(MISO) 从设备输出/主设备输入 3 WP 写保护(低电平有效) 4 VSS 地 5 SI(MOSI) 主设备输出/从设备输入 6 SCK 时钟输入 7 HOLD 保持(可选功能) 8 VCC 电源输入

四、典型应用场景

M95640-DRDW8TP/K凭借宽温、高可靠、小尺寸等特性,广泛应用于以下领域:

  1. 工业控制自动化:PLC模块、电机驱动器、传感器节点的校准参数/状态阈值存储;
  2. 消费电子:智能家居设备(智能灯、环境传感器)、遥控器、小型家电的配置参数存储;
  3. 物联网(IoT)设备:低功耗电池节点(如户外环境监测仪)的状态数据存储,适配1.7V低电压;
  4. 车载辅助系统:车载小模块(胎压监测副件、车载充电器)的参数存储(宽温适配车载环境);
  5. 医疗电子:小型医疗设备(体温计、血糖仪)的校准数据存储(潜在适配性,需结合医疗认证)。

五、核心竞争优势

  1. 宽电压全兼容:1.7V~5.5V覆盖主流电源系统,无需电平转换;
  2. 工业级宽温设计:-40℃~+105℃适应极端环境,无需额外散热防护;
  3. 高可靠性保障:400万次写寿命+50年数据保留,满足长期稳定运行需求;
  4. 高速SPI通信:20MHz时钟提升读写效率,适配实时系统;
  5. 小尺寸封装:8-TSSOP节省PCB空间,支持小型化产品设计;
  6. 灵活操作模式:字节/页写擦除无需整体擦除,操作精准高效。

该产品是ST EEPROM系列中针对工业与消费电子平衡需求的核心型号,兼具高可靠性与成本优势,是小容量非易失性存储的优选方案。

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
