ATTINY404-SSNR 产品概述

一、简介

ATTINY404-SSNR 是 MICROCHIP(美国微芯)推出的一款小型 8 位 AVR 单片机,采用 14 引脚 SOIC 封装(SSNR)。器件工作频率最高可达 20 MHz,工作电压范围宽(1.8V~5.5V),并在工业级温度范围(-40°C ~ 105°C)内可靠工作,适合对尺寸和成本敏感但要求丰富接口与外设的嵌入式应用。

二、主要规格一览

  • 核心/架构:8 位 AVR 内核,内置振荡器,最高 20 MHz。
  • 存储:程序闪存 4 KB(4K x 8);EEPROM 128 x 8;SRAM 256 x 8。
  • I/O 与外设:12 个通用 I/O;支持 I²C、SPI、UART/USART 通信。
  • A/D:10 通道 10 位 ADC(10x10b)。
  • 其他外设:PWM、看门狗(WDT)、欠压检测/复位、上电复位(POR)等。
  • 封装与引脚:表面贴装 SOIC-14(0.154", 3.90 mm 宽)。
  • 供电与温度:Vcc 1.8V~5.5V;工作温度 -40°C~105°C(TA)。

三、关键特性与优势

  • 宽电压范围支持单节锂电池及 5V 系统,便于电源设计与多平台兼容。
  • 小封装、低成本、功能全面,适合空间受限的控制与采集模块。
  • 内置多种常用外设(串口、PWM、ADC、WDT),可完成传感器采集、通信与简单控制任务而无需外部复杂器件。
  • 10 位 ADC 多通道采样适合中精度模拟量测量与电池检测。

四、典型应用场景

  • 低功耗传感节点、便携测量仪器、遥控器与按键控制器。
  • 小型电机/舵机控制(利用 PWM)、LED 驱动与灯光调节。
  • 工业/车载边缘控制(宽温度支持)。
  • 简单网关与串行外设集中器,用于 I²C/SPI 设备管理。

五、设计与开发建议

  • 电源旁路:Vcc 引脚靠近器件布置 0.1 µF 陶瓷电容以抑制瞬态噪声,重要电源路径考虑加 1 µF 多层电容。
  • 复位与欠压:若对启动可靠性要求高,保留外部复位电路或上电复位增强措施。
  • ADC 采样:模拟输入宜使用稳定参考并做好输入滤波/阻抗匹配以提高测量精度。
  • IO 驱动:注意在不同 Vcc 下 I/O 驱动能力与容性负载,避免超出输出电流等级。
  • 软件生态:可使用 Microchip 提供的开发工具及开源 AVR-GCC 工具链进行固件开发,配合 Microchip 的 IDE 与调试器可加速开发与验证。

六、选型与采购注意

选择 ATTINY404-SSNR 时,确认所需 I/O、存储空间与 ADC 通道是否满足应用需求。SOIC-14 封装适合贴片生产与手工焊接验证。基于 Microchip 品牌,供货与技术支持成熟,适合中小批量至量产项目采用。

总结:ATTINY404-SSNR 以其紧凑封装、宽电压和完整的基础外设组合,为对成本、尺寸与可靠性有严格要求的应用提供了一个高性价比的 AVR 解决方案。

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
