MCP23017T-E/SS規(guī)格書詳情
MCP23017T-E/SS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MCP23017T-E/SSI/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 MCP23017/MCP23S17 (MCP23X17) device family provides 16-bit, general purpose parallel I/O expansion for I2C bus or SPI applications. The two devices differ only in the serial interface:
? MCP23017 – I2C interface
? MCP23S17 – SPI interface
The MCP23X17 consists of multiple 8-bit configuration registers for input, output and polarity selection. The system master can enable the I/Os as either inputs or outputs by writing the I/O configuration bits (IODIRA/B).
The data for each input or output is kept in the corresponding input or output register. The polarity of the Input Port register can be inverted with the Polarity Inversion register. All registers can be read by the system master.
Features
? 16-Bit Remote Bidirectional I/O Port:
- I/O pins default to input
? High-Speed I2C Interface (MCP23017):
- 100 kHz
- 400 kHz
- 1.7 MHz
? High-Speed SPI Interface (MCP23S17):
- 10 MHz (maximum)
? Three Hardware Address Pins to Allow Up to Eight Devices On the Bus
? Configurable Interrupt Output Pins:
- Configurable as active-high, active-low or open-drain
? INTA and INTB Can Be Configured to Operate Independently or Together
? Configurable Interrupt Source:
- Interrupt-on-change from configured register defaults or pin changes
? Polarity Inversion Register to Configure the Polarity of the Input Port Data
? External Reset Input
? Low Standby Current: 1 μA (max.)
? Operating Voltage:
- 1.8V to 5.5V @ -40°C to +85°C
- 2.7V to 5.5V @ -40°C to +85°C
- 4.5V to 5.5V @ -40°C to +125°C
