R7FA2E1A72DFM#AA0 产品概述
一、概述
R7FA2E1A72DFM#AA0 是瑞萨（Renesas Electronics America Inc.）RA2E1 系列的 32 位微控制器，基于 ARM® Cortex®-M23 内核，主频 48MHz，面向嵌入式、低功耗和工业控制应用。器件为在售产品，采用 64 引脚 LFQFP（10×10）封装，托盘包装，基本件号 R7FA2E1。
二、存储与内核特性
- 程序闪存：64KB（64K x 8）；
- EEPROM：4KB（4K x 8）用于非易失性参数存储；
- SRAM：16KB（16K x 8）用于运行时数据与堆栈；
- 32 位 ARM Cortex‑M23 内核，48MHz 提供良好的功耗与性能平衡。
三、片上外设与接口
- 串行通信：I²C、SPI、UART/USART 满足常见外设和传感器连接需求；
- A/D：13 路 12-bit SAR ADC（13×12b），适合多通道模拟传感器采样；
- 定时与控制：PWM 外设、DMA、看门狗（WDT）；
- 电源管理：低压检测（LVD）与上电复位（POR）机制，提高系统可靠性；
- 通用 I/O：56 个可用 I/O，支持多种功能复用。
四、电气与机械特性
工作电压范围宽：1.6V ~ 5.5V，适应电池供电与多种电源拓扑；工作温度范围 -40°C ~ +85°C（TA），适合工业级环境；振荡器类型为外部晶振，封装为表面贴装 64‑LQFP。
五、典型应用场景
适用于工业控制、传感器节点、消费类设备、家电控制、低功耗物联网终端、便携式测量仪表及电机/伺服控制等场合，尤其在对尺寸、成本与功耗有要求且需多模拟通道与丰富通信接口的设计中表现突出。
六、设计与布局建议
- 电源：为 MCU 核心与外设配置独立去耦电容，注意上电复位及稳压器的软启动；
- 模拟接口：ADC 引脚与模拟地分离，靠近器件布置采样电阻与滤波；
- 晶振：外部晶振元件紧靠振荡器引脚布置，减小干扰；
- 外设保护：对外部通信总线添加防浪涌/ESD 保护，特别是在工业现场应用。
七、采购与封装信息
完整料号：R7FA2E1A72DFM#AA0；封装 64‑LFQFP（10×10）；包装类型：托盘；器件状态：在售。基本产品编号：R7FA2E1。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
