The MCP23017-E/SO is a popular 16-bit I/O expander integrated circuit (IC) manufactured by Microchip Technology. It allows you to add 16 general-purpose input/output (GPIO) pins to a microcontroller using only two pins via the I2C serial interface.
Features
• AEC-Q100 Qualified
• 16-Bit Remote Bidirectional I/O Port (Pins GPA7, GPB7 are output only for MCP23017):- I/O pins default to input
• High-Speed I2C Interface (MCP23017):- 100kHz- 400kHz- 1.7MHz
• High-Speed SPI Interface (MCP23S17):- 10MHz (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: 1µA (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
