MCP23017E/SP IC I/O EXPANDER I2C 16B 28SDIP

The MCP23017E/SP is a versatile 16-bit I/O expander with an I2C interface, housed in a 28-pin SDIP (Skinny Dual In-line Package). This integrated circuit (IC) provides additional digital input/output pins for microcontrollers, allowing you to expand the capabilities of your embedded systems without using up valuable microcontroller pins. The MCP23017E/SP communicates with the microcontroller via the I2C serial interface, requiring only two pins for communication. This simplifies the wiring and reduces the complexity of the circuit. The 16 I/O pins can be individually configured as either inputs or outputs, providing flexibility in designing your application. The MCP23017E/SP features interrupt capability, allowing it to signal the microcontroller when an input pin changes state.

This eliminates the need for the microcontroller to constantly poll the I/O expander, saving processing power. The IC also includes internal pull-up resistors, which can be enabled or disabled on each pin. This simplifies the design of circuits that require pull-up resistors. The MCP23017E/SP operates over a wide voltage range, making it compatible with various microcontroller systems. Its low power consumption makes it suitable for battery-powered applications. The SDIP package allows for easy insertion and soldering on printed circuit boards (PCBs) and breadboards.
