ATTINY1614-SSNR 产品概述

一、产品简介

ATTINY1614-SSNR 是 Microchip(美国微芯)推出的 8 位 AVR 单片机,基于经典的 AVR 指令集,面向低功耗、小尺寸和成本敏感型嵌入式应用。器件具有 16KB 的闪存程序空间、2KB RAM 和 256Byte EEPROM,最大工作主频 20MHz,工作电压范围 1.8V~5.5V,工作温度范围 -40℃~+105℃,封装为 SOIC-14,提供约 12 个通用 I/O 引脚,内置振荡器,并集成 10-bit ADC 与 8-bit DAC 等模拟功能。

二、主要性能特点

  • 处理能力:AVR 8-bit 内核,最高 20MHz,适合控制类任务、简单信号处理与通信协议实现。
  • 存储资源:16KB FLASH(程序)、2KB SRAM(运行数据)、256Byte EEPROM(非易失性参数存储)。
  • 外设与 I/O:约 12 个通用 I/O,适配小型板级连接;集成 10-bit ADC 用于模拟传感器采集,8-bit DAC 便于模拟输出或参考信号生成。
  • 时钟与电源:内置振荡器可实现免晶振设计,支持 1.8V 至 5.5V 宽电压供电,便于电池或多电压系统集成。
  • 工业级温度范围:-40℃ 至 +105℃,适合要求较高环境耐受性的应用。
  • 封装与品牌:SOIC-14 商业封装,Microchip 原厂,便于采购与可靠性保证。

三、典型应用场景

  • 低功耗物联网节点:借助内置振荡器与低电压工作特性,可在电池供电的传感器节点中长期运行。
  • 工业控制与传感:10-bit ADC 与耐高温特性适合工业现场采集与简单控制回路。
  • 家用及消费电子:作为键盘控制、背光驱动、简单电机/继电器控制等微控制单元使用。
  • 人机界面与信号输出:利用 DAC 输出模拟参考或驱动小型模拟电路,实现更丰富的 HMI 设计。

四、系统设计与工程注意事项

  • 电源设计:建议在 VCC 近端放置 0.1µF 陶瓷旁路电容,减少振荡器与 ADC 的噪声干扰;若在 1.8V 工作时,应检查外设电平兼容性。
  • ADC 与 DAC:ADC 精度受供电与参考电压影响,使用稳压或外部参考能显著改善测量稳定性;DAC 为 8-bit,适合粗调与模拟驱动场景。
  • 引脚与封装:SOIC-14 便于原型和小批量生产,布板时注意地线回流与敏感信号隔离。
  • 编程与调试:器件支持单线编程/调试方案(UPDI),可使用 Microchip 提供的开发工具链与常见 UPDI 编程器进行固件烧写与调试。
  • EEPROM 与闪存:请在设计中妥善安排 EEPROM 写入频率,以延长器件寿命;FLASH 可用作程序和只读常量存储。

五、选型与购买建议

ATTINY1614-SSNR 适合需要中等存储与基本模拟接口、要求低成本与小封装的嵌入式方案。选型时按系统电压、所需 I/O 数量、ADC/DAC 精度及工作温度范围综合评估。作为 Microchip 系列器件,配套软件与参考设计丰富,可缩短开发周期。购买时注意型号后缀与封装(SSNR 对应 SOIC-14),并优先选择正规代理以保证质量与技术支持。

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
