瑞萨R5F21258SNFP#V2 16位单片机产品概述

一、核心架构与运算性能

R5F21258SNFP#V2采用瑞萨自研R8C系列16位CPU内核,这是针对嵌入式控制优化的低功耗架构——指令集兼顾代码密度与执行效率,相比同主频8位MCU,数据处理能力提升约2倍,可支持简单PID控制、数据滤波等实时算法。

CPU最大主频达20MHz,无需外部晶振即可依赖内置振荡器稳定运行,减少外围器件成本;内核支持待机/休眠/停止等多种低功耗模式,适合电池供电或功耗敏感型应用(如小型传感器节点)。

二、存储资源配置

  • 程序存储器:64KB内置FLASH,采用瑞萨成熟的嵌入式非易失性存储技术,擦写周期≥10万次,数据保持时间≥10年(25℃环境下);支持在线编程(ICP)与在应用编程(IAP),便于产品量产与固件远程升级。
  • 数据存储器:3KB SRAM,足够存储临时运算数据、变量及堆栈,满足小型控制程序的内存需求;无需外部RAM扩展即可完成大部分基础功能开发。

三、外设功能与接口

  1. 通用I/O口:共41个双向I/O引脚,支持上拉/下拉电阻配置,多数引脚可复用为外设功能(如ADC输入、定时器输出),提升引脚利用率;
  2. ADC模块:内置10位分辨率逐次逼近型ADC,采样精度满足一般模拟信号采集需求(如传感器电压、电流监测),通道数适配小型系统的多模拟量输入场景;
  3. 辅助外设:内置多个16位定时器(支持PWM输出、定时中断)、串行通信接口(UART、SPI等),可直接对接传感器、蓝牙模块等外围器件。

四、封装与电气特性

  • 封装形式:52引脚LQFP封装(10×10mm),引脚间距0.8mm,属于小尺寸高密度封装,适合PCB空间受限的紧凑型产品设计(如车载小模块、穿戴设备);
  • 电气参数:
    • 工作电压:2.2V~5.5V宽电压范围,兼容3.3V与5V电源系统,适配2节AA电池、工业电源(波动±10%)等不同供电场景;
    • 工作温度:-20℃~+85℃工业级温度范围,可稳定运行于户外、车间等温差较大的环境;
    • 功耗:典型工作电流(20MHz、3.3V)约10mA,休眠模式电流低至μA级,降低系统待机功耗。

五、典型应用场景

R5F21258SNFP#V2凭借平衡的性能、成本与可靠性,广泛适用于以下场景:

  1. 小型工业控制:电机转速监测、温度/压力传感器数据采集、小型PLC辅助模块;
  2. 消费类电子:智能加湿器、小型打印机、家用安防传感器;
  3. 汽车电子:车载胎压监测接收器、车内氛围灯控制、后视镜辅助模块;
  4. 物联网终端:低功耗环境监测节点(如温湿度采集)、智能门锁辅助单元。

该产品是瑞萨R8C系列中高性价比的16位MCU,适合对性能要求高于8位、无需复杂外设扩展的嵌入式控制场景,兼顾开发成本与系统可靠性。

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
