PCF85176T/1Y 产品概述

一、产品概述

PCF85176T/1Y 是恩智浦(NXP)面向低复用(low multiplex)液晶显示的通用驱动器,支持 40 x 4 位显示配置,适用于字符型与简单图形型 LCD 面板。器件通过 I2C 总线控制,工作电压范围宽(1.8V ~ 5.5V),并在-40℃到+85℃工业温度范围内可靠工作,适合对功耗和体积有要求的嵌入式系统应用。

二、主要参数

  • 工作电压:1.8V ~ 5.5V
  • 接口类型:I2C(串行总线)
  • 工作电流:典型值 3.5 μA(低功耗运行,有利于电池供电设备)
  • 偏压选择:1/3、1/2(可根据面板与对比度要求选择)
  • 工作温度:-40℃ ~ +85℃
  • 显示配置:40 x 4 bit(支持大字符行数/列数组合)
  • 品牌与封装:NXP,TFSOP-56-6.1mm

三、功能与特性

  • 采用 I2C 接口,简化与 MCU 的连线与控制逻辑,节省 GPIO 资源;
  • 低功耗设计,待机/工作电流小,适合便携设备与电池供电场合;
  • 支持两种偏压分压比(1/3、1/2),便于适配不同类型的 LCD 面板对对比度的需求;
  • 宽电压工作范围,兼容多种供电架构;
  • 封装紧凑,便于 PCB 布局与空间受限的产品设计。

四、典型应用场景

  • 手持仪器与便携设备(如便携测量仪、手持终端);
  • 工业控制面板与人机界面(HMI);
  • 家用电器的状态显示与控制界面;
  • 任何需要低功耗字符/简单图形显示的小型嵌入式系统。

五、设计与使用建议

  • 在 VCC 与 GND 之间靠近封装加 0.1 μF 陶瓷去耦电容,抑制电源噪声;
  • I2C 总线 SDA/SCL 引脚需外接上拉电阻,典型值 4.7kΩ(根据总线速率与节点数调整);
  • 根据面板建议选择偏压比 1/3 或 1/2,并在调试阶段确认对比度效果;
  • 注意 PCB 布局时为 LCD 驱动器预留散热与地平面,避免信号线与高频噪声源并行;
  • 在多器件系统中注意 I2C 地址管理与总线完整性。

六、封装与环境可靠性

器件采用 TFSOP-56(6.1 mm)小型封装,适合空间受限的应用,同时支持工业温度等级(-40℃ 至 +85℃),满足苛刻环境下的长期可靠性需求。

以上为 PCF85176T/1Y 的简介与设计参考,开发时建议结合具体面板与系统需求查阅官方数据手册以获得详细寄存器、时序与电气特性信息。

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
