PCF8551ATT/AY 产品概述

一、产品概览

PCF8551ATT/AY 是恩智浦(NXP)推出的一款字符型 LCD 驱动器,支持最多 18 位字符显示,工作电压范围覆盖 2.5V、3.3V 与 5V,封装为 48 引脚 TSSOP。器件集成升压电路以生成 LCD 所需偏压,并内置振荡器以驱动多路复用与时序,旨在简化 LCD 模块的外围电路、降低总体 BOM 成本并缩短开发周期。

二、主要功能与特点

  • 支持 18 位字符显示,适配常见字符型 LCD 排列;
  • 宽电源兼容:2.5V / 3.3V / 5V 多电压工作,便于与不同逻辑电平系统配合;
  • 集成升压电路:为 LCD 提供所需的偏压电平,减少或消除外部高压生成器与相关滤波器件;
  • 内置振荡器:提供驱动时钟与多路复用定时,降低对外部时钟源的依赖;
  • 48 引脚 TSSOP 封装,便于表面贴装与自动化生产;
  • 面向低功耗设计,适合电池供电与便携设备场景。

三、典型应用场景

  • 家用电器面板(微波炉、空调、洗衣机等);
  • 仪器仪表与工业控制显示;
  • 医疗设备中的字符显示单元;
  • 手持终端、计量表与消费电子产品的状态/数值显示。

四、设计与使用建议

  • 电源侧应使用适当的去耦电容,靠近器件 VDD 引脚布置以抑制开关噪声;
  • 升压输出及振荡部分建议按参考设计布置滤波与旁路电容,以保证显示稳定性与低噪声;
  • LCD 引脚走线要注意阻抗匹配与屏蔽,避免长导线引入辐射与干扰;
  • 在电池供电系统中关注升压转换效率与静态电流,必要时采用电源管理策略延长续航。

五、封装与订货信息

封装型号:TSSOP-48。订货型号示例:PCF8551ATT/AY(恩智浦品牌)。在选型与采购前建议参考官方数据手册以获取完整电气参数、引脚定义与典型应用电路。若需后续的电路参考设计或替代器件建议,可进一步沟通。

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
