LPC1112FHN33/202K 产品概述

一、概述

LPC1112FHN33/202K 是恩智浦(NXP)推出的一款基于 ARM Cortex‑M0 内核的 32 位微控制器,最高主频 50MHz,片上程序存储器为 16KB FLASH,片上 RAM 2KB。器件提供约 28 路可配置 I/O,内置振荡器,工作电压范围 1.8V ~ 3.6V,工作温度范围 -40℃ ~ +85℃,封装为 HVQFN‑32‑EP(7x7),适合对体积、功耗与成本有严格要求的嵌入式控制应用。

二、主要特性

  • ARM Cortex‑M0 32 位内核,性能与低功耗兼顾,最高 50MHz。
  • 16KB FLASH 程序存储与 2KB RAM,满足中小规模嵌入式程序需求。
  • 大约 28 路多功能 I/O 引脚,支持外设复用,适配多种接口需求。
  • 内置振荡器,简化时钟设计,支持片上时钟/电源管理以降低功耗。
  • 工作电压 1.8V3.6V,工业级温度(-40℃+85℃)范围适应较宽的应用环境。
  • 封装为 HVQFN‑32 带外露焊盘(EP),有利于散热与接地。

(器件常用片上外设包括定时器、串行通讯接口如 UART/SPI/I2C、ADC 等,具体外设型号/数量请以器件手册为准。)

三、封装与引脚建议

HVQFN‑32‑EP(7x7)封装占板面积小,外露焊盘用于接地与散热。布局时建议:

  • 在外露焊盘下方打通多处过孔接到地平面,提高散热与接地完整性。
  • 关键电源引脚处放置 0.1µF~1µF 去耦电容,靠近器件引脚布局。
  • 将模拟信号与高速数字信号分区,减小干扰;敏感模拟输入宜短线并靠近 ADC 引脚。
  • 预留 SWD 调试/编程 接口引脚,便于在线调试与固件下载。

四、典型应用场景

  • 低功耗物联网终端与传感节点。
  • 消费类小家电与智能配件控制器。
  • 工业传感与简单控制系统。
  • 人机界面(按键、LED 驱动)、协议桥接与数据采集等嵌入式应用。

五、设计与使用要点

  • 电源设计:确保稳定电压源并做好去耦与滤波;考虑上电复位和欠压保护。
  • 时钟选择:内置振荡器可降低 BOM,必要时外接晶振以获得更高精度。
  • 软件优化:16KB FLASH 与 2KB RAM 资源有限,建议使用精简的运行时库与优化编译选项,合理分配缓冲区与栈空间。
  • 调试与烧录:使用 SWD 等工业标准调试接口进行在电调试和程序下载。
  • 热与 EMI 管理:HVQFN 外露焊盘和走线布局对热管理与电磁兼容性能影响明显,需在 PCB 布局阶段考虑。

六、选型建议

在选型时请核对具体封装引脚分配、片上外设数量与 ADC 分辨率等详细参数是否满足项目需求。若应用对程序容量或运行 RAM 有较高要求,可考虑更高容量的同系器件或其他系列芯片。

总体而言,LPC1112FHN33/202K 适合对成本、体积与功耗敏感且对计算与外设需求适中的嵌入式控制应用。若需进一步的引脚图、外设清单或参考电路,请查阅 NXP 官方数据手册与参考设计。

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
