HT16C21A-28SSOP 产品概述

一、产品简介

HT16C21A 为 HOLTEK(台湾合泰/盛群)推出的一款高集成度显示驱动器,采用 SSOP-28 封装,适用于便携与低功耗 LCD/点阵显示场合。器件内置升压电路与 32kHz 振荡器,简化外部电源与时钟设计,便于在电池供电系统中实现稳定显示。

二、关键规格

  • 工作电压:2.4V ~ 5.5V
  • 接口类型:I²C(双线串行总线)
  • 占空比(Multiplex):1/8、1/4
  • 偏压(Bias):1/4、1/3
  • 工作电流:典型 18 µA(低功耗运行)
  • 振荡频率:内置 32 kHz 振荡器
  • 显示配置支持:16×8 bit、20×4 bit 等常见组合
  • 工作温度:-40℃ ~ +85℃

三、电气与时序特性

器件支持宽电压范围 2.4V~5.5V,适配多种电池或稳压供电方案。内置升压电路可为 LCD 提供所需偏压,减少外部生成高压的元件。典型工作电流仅 18µA,适合对功耗敏感的手持终端。I²C 接口使主控 MCU 与显示驱动之间通信简单可靠。

四、显示支持与驱动特性

HT16C21A 可驱动多种点阵或字符型显示模块,支持 1/8 与 1/4 占空比以及 1/4、1/3 偏压组合,兼容常见 LCD 的驱动要求。内部振荡器(32kHz)为驱动时序提供参考,配合内部升压电路可直接驱动小至中等规模的显示面板。

五、接口与控制

通过 I²C 总线进行寄存器读写与显示数据传输,便于与主控微控制器对接。I²C 的引脚与时序需符合主流规范,器件内部含常用控制寄存器,可实现显示开关、偏压与占空比设置等功能,软件层面控制灵活。

六、封装、环境与可靠性

HT16C21A 提供 SSOP-28 封装,便于中小批量生产与贴片工艺,工作温度范围 -40℃~+85℃ 满足工业级应用需求。器件内部集成关键功能可减少外部元件,提升整体系统可靠性与抗干扰能力。

七、典型应用

  • 手持仪表、便携式终端显示
  • 小型字符/点阵 LCD 模块驱动
  • 低功耗消费电子(例如遥控器、计时器)
  • 工业控制面板的简单显示单元

八、设计与使用建议

  • 电源端建议近芯片放置 0.1µF 去耦电容,以抑制升压切换噪声。
  • 若对显示对比度或刷新频率有特殊要求,需在设计初期确认占空比与偏压组合。
  • I²C 总线拉升电阻需根据系统电压与总线长度选取,避免通信异常。
  • 开发阶段建议参考 HOLTEK 官方数据手册与评估板进行功能验证,保证驱动参数匹配目标面板。

订货型号一般以 HT16C21A-28SSOP 标识,选型时请核对官方数据手册以获取完整时序、寄存器定义与电气特性。

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
