二、存储体系结构

该MCU集成三类存储单元,满足程序、数据与掉电保存的全场景需求:

  1. 程序存储器:128KB FLASH,支持在线编程(ICP)与在线调试(ICD),擦写次数≥10万次,可满足产品生命周期内的固件升级需求;
  2. 数据存储器:12KB RAM,用于实时数据运算、堆栈操作及变量存储,足够支撑中等规模的应用程序(如带多个通信接口的控制逻辑);
  3. 非易失性存储:8KB EEPROM,无需外接独立EEPROM即可实现参数配置、校准数据等掉电保存,降低系统复杂度与成本。

三、外设功能特性

作为通用型MCU,R5F100LGAFA#50配备丰富外设,适配多领域应用:

  1. 数字IO口:共48个通用IO,支持上下拉电阻配置、复用功能(如ADC输入、定时器输出),部分IO具备20mA高驱动能力,可直接驱动小型负载(如LED、继电器);
  2. 模拟外设:集成10位分辨率ADC,单端采样通道数≥16(部分IO复用),采样率可达1Msps,满足快速信号采集(如传感器实时数据)需求;
  3. 定时器与通信:内置3个16位定时器(含PWM输出功能,支持相位控制)、1个看门狗定时器(WDT)保障系统可靠性;支持UART(最多3路)、SPI(2路)、I2C(2路)等串行通信接口,可与传感器、显示屏、无线模块等外设无缝对接。

四、封装与工作环境

采用LQFP64封装(10mm×10mm,引脚间距0.5mm),体积紧凑,适配小型化产品设计;工作电压范围1.6V5.5V,覆盖电池供电(如3.7V锂电池)、5V工业电源等场景;工作温度-40℃+85℃,符合工业级标准,可在低温户外环境或高温车载辅助设备中稳定运行。

五、典型应用场景

基于其性能与特性,R5F100LGAFA#50广泛适用于以下领域:

  1. 工业控制:小型PLC、传感器节点、小型电机控制模块(如步进电机驱动);
  2. 消费电子:智能家居设备(如智能插座、温湿度传感器)、小型家电(如加湿器、空气净化器);
  3. 医疗设备:小型便携式医疗仪器(如血糖监测仪、体温计);
  4. 物联网终端:低功耗物联网节点(如环境监测站、智能穿戴辅助模块)。

六、选型优势分析

相比同类产品,R5F100LGAFA#50具备以下核心优势:

  1. 性能成本平衡:16位内核性能优于8位MCU,成本低于32位MCU,是中等复杂度应用的最优选择;
  2. 集成度高:内置EEPROM无需外挂,减少硬件设计复杂度与BOM成本;
  3. 低功耗特性:RL78内核支持HALT(停止CPU)、STOP(停止时钟)等低功耗模式,静态电流低至μA级,适合电池供电的便携设备;
  4. 开发支持完善:瑞萨提供e2studio开发环境、HAL库、参考设计等,加速产品开发周期;
  5. 可靠性强:宽电压、工业级温度范围,以及瑞萨的高可靠性制造工艺,保障产品长期稳定运行。

该产品凭借平衡的性能、丰富的外设与高集成度,成为工业、消费电子等领域中等复杂度应用的理想选择。

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
