NT3H2211W0FHKH 产品概述

NT3H2211W0FHKH 是恩智浦(NXP)面向近场通信(NFC)与13.56MHz 射频识别应用的非接触式 RF 接口 IC。器件支持 ISO 14443 标准(Type A),同时提供主机通信接口,适合在智能标签、电子名片、配件配对及物联网识别等场景中作为低功耗、体积微小的 NFC 识别与数据交换器件使用。

一、主要特点

  • 支持协议:ISO 14443(Type A)兼容 NFC Forum 规范,工作频率 13.56 MHz。
  • 主机接口:I2C 与 SPI(片上寄存器与数据存取),便于与 MCU/应用处理器对接。
  • 工作电压:1.67 V ~ 3.6 V,适配多种供电域(包括单节锂电池或 3.3V 系统)。
  • 封装:XQFN-8(1.6 mm × 1.6 mm),占板面积小,适合空间受限的便携式产品。
  • 低功耗特性,支持睡眠/唤醒机制以延长系统待机时间。

二、主要技术参数

  • 射频频率:13.56 MHz,符合近场通信应用要求。
  • 协议兼容:ISO 14443 / NFC Forum。
  • 接口电气特性:典型 I2C 电平兼容标准逻辑电压,支持主/从架构;SPI 接口用于高速主机访问(具体时序与最大速率请参考数据手册)。
  • 环境与可靠性:工业级工作范围(请以官方资料中温度与 ESD 规范为准)。

三、封装与引脚提示

器件采用 XQFN-8 小型封装(1.6×1.6 mm),引脚排列紧凑。典型 PCB 布局建议:

  • 在 VCC 与 GND 引脚附近放置去耦电容(典型 100 nF + 1 µF 组合),靠近芯片引脚。
  • 为 RF 天线留出合适的板边或独立线圈区域,注意周围金属件对天线性能的影响。
  • I2C 总线侧建议使用上拉电阻,若与多个从设备共用请注意总线电容限制。

四、典型应用场景

  • 智能标签与门禁卡片(短距离识别与授权)。
  • 配件配对与消费电子设备身份识别(耳机、手表、智能家居配件)。
  • 物联网节点的快速配网与凭证读取。
  • 电子名片、智能海报与交互式展示。

五、设计与选型建议

  • 天线设计为关键点:推荐与天线工程师协作,确保谐振频率与匹配网络优化,避免 PCB 噪声源靠近天线。
  • 电源完整性:使用良好的电源去耦并保持地平面连续,减少射频干扰对射频接收灵敏度的影响。
  • 接口兼容性:根据主控器件选择 I2C 或 SPI 接入方式,评估访问延迟与带宽需求后决定接口模式。
  • PCB 布局:保持 RF 区域清洁,避免过孔与金属覆盖影响天线场分布。

六、注意事项与兼容性

  • 实装前请参阅恩智浦官方数据手册与应用笔记,确认引脚功能、时序限制及推荐外围元件值。
  • 在系统设计中需兼顾电磁兼容(EMC)与射频法规要求,必要时进行符合性测试。
  • 若需特定功能(安全加密、能量采集、记忆容量等)或更详细的时序与寄存器说明,请参考 NXP 正式技术文档或联系供应商获取支持。

本概述提供产品的功能定位与工程应用建议,便于在方案评估阶段快速判断 NT3H2211W0FHKH 是否满足项目需求。实际设计与量产前,请以恩智浦最新数据手册为准并完成验证测试。

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
