ATMEGA88PA-MU 产品概述

一、概要介绍

ATMEGA88PA-MU 是 Microchip(美国微芯)出品的一款基于 AVR 8-bit 内核的低功耗单片机。器件配备 8KB Flash 程序存储、1KB RAM 与 512Byte EEPROM,最高主频 20MHz,工作电压范围宽(1.8V 至 5.5V),工作温度覆盖工业级 -40°C 到 +85°C,内置振荡器,适用于体积受限且需可靠长期运行的嵌入式系统。

二、主要规格一览

  • CPU 内核:AVR 8-bit;最高主频:20MHz
  • 程序存储:8KB Flash;RAM:1KB;EEPROM:512Bytes
  • I/O 数量:23 个通用 I/O 引脚
  • ADC:10-bit 分辨率多路模数转换器
  • 工作电压:1.8V ~ 5.5V;工作温度:-40°C ~ +85°C
  • 封装:MLF-32(5×5)型号后缀 MU;品牌:Microchip(美国微芯)
  • 时钟:片内振荡器(支持外部晶振/时钟源)

三、外设与功能亮点

ATMEGA88PA 提供丰富的片上外设,常见用于控制与通信场景:多通道 10-bit ADC、定时器/计数器(含 PWM 输出)、硬件 SPI、I2C (TWI)、UART/USART、模拟比较器、看门狗定时器及多种省电模式。器件支持在系统编程(ISP)并兼容 debugWIRE 调试(需关注引脚复用与复位功能)。

四、电源与可靠性建议

该器件支持 1.8V 到 5.5V 的宽电源范围,便于与不同电源域的系统集成。开发时应注意:在 AVCC/AREF 引脚处提供低杂讯电源与去耦电容;在 Vcc 处放置近端 0.1µF 去耦;若使用外部晶振,布局需尽量靠近晶体并使用地平面隔离模拟与数字地。工业级温度范围适合长期运行和户外/工业场景。

五、封装与板级注意事项

MU 系列的 MLF-32(5×5)封装占板面积小,适合高密度 PCB 设计。布线要点包括:电源与地的充足铺铜、AVCC 单独供电路径、ADC 输入走线避免长线和强干扰源、保留编程与调试接口(ISP)走线并留出焊盘以便生产编程和调试。

六、典型应用与选型建议

适用于便携式产品、传感器节点、工业控制、人机界面、小型电机驱动、消费电子及教育开发平台等。选型时若需更多 Flash 或更大 RAM/EEPROM,应对比同系列其他型号;若对封装焊接可维护性有更高要求,可考虑引脚可焊的 TQFP 封装版本。总体而言,ATMEGA88PA-MU 在功能与成本之间具有良好平衡,适合对电源范围、工业温度与通用外设有需求的小型应用。

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
