MCP23016-I/SP集成電路（IC）的I/O擴展器規(guī)格書PDF中文資料

MCP23016-I/SP屬于集成電路（IC）的I/O擴展器。由微芯科技股份有限公司制造生產(chǎn)的MCP23016-I/SPI/O 擴展器該系列器件可與微控制器、微處理器或類似器件結(jié)合使用，目的是增加可用于連接外設(shè)的信號連接數(shù)量。典型的工作概念涉及使用串行通信，只需主機設(shè)備上的幾根 I/O 線，即可讀/寫擴展器設(shè)備上的許多輸入/輸出引腳的狀態(tài)。該技術(shù)的通信速度不佳，但連通性較高，最適合快速響應(yīng)不是很關(guān)鍵的應(yīng)用，例如許多人機界面應(yīng)用。

DEVICE OVERVIEW

The MCP23016 device provides 16-bit, general purpose, parallel I/O expansion for I2C bus applications. This device includes high-current drive capability, low supply current and individual I/O configuration. I/O expanders provide a simple solution when additional I/Os are needed for ACPI, power switches, sensors, push buttons, LEDs and so on.
