MCP23017T-E/ML 是由美国微芯(Microchip)公司生产的一款高性能、16 位 I²C 总线 I/O 扩展器。该器件专为需要扩展微控制器或其他主机设备的输入/输出能力而设计,特别适用于各种嵌入式系统和工业自动化应用。
MCP23017T-E/ML 支持高达 1.7MHz 的 I²C 总线时钟频率,这使得它能够在高速数据传输场景中发挥作用。同时,器件还支持标准模式(100kHz)、快速模式(400kHz)和高速模式(1.7MHz),提供灵活的配置选项。
该器件的 16 个 I/O 引脚都是可编程的,可以配置为输入或输出。每个 I/O 引脚都具有独立的方向控制寄存器,这意味着你可以根据具体应用需求灵活地设置每个引脚的功能。
MCP23017T-E/ML 提供了强大的中断功能。它支持两种中断模式:端口A和端口B的任意变化都会触发中断,或者只有当配置的特定引脚发生变化时才触发中断。这一功能大大减少了主机设备对 I/O 状态的轮询需求,从而提高系统整体效率。
器件内置了电源复位功能,在电源上电时自动将所有寄存器初始化为默认状态。这确保了设备在启动过程中始终处于知名状态,有助于提高系统的可靠性和稳定性。
每个 I/O 引脚都支持推挽式输出,这意味着它们可以驱动较大的负载,如 LED、继电器等。这种输出类型在需要驱动外部设备时尤为有用。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
