MCP23017-E/SP General Description

The MCP23017-E/SP is an 16-bit I/O expander with I2C interface from Microchip Technology. It offers 16 GPIO pins that can be individually configured as input or output, allowing for additional digital I/O capabilities in embedded systems. The device operates on a wide supply voltage range of 1.8V to 5.5V, making it suitable for a variety of applications. It also features programmable pull-up resistors, interrupt support, and a configurable hardware address. The MCP23017-E/SP communicates with the microcontroller over a 2-wire I2C serial interface, simplifying connections and reducing pin count. It can be used in conjunction with other devices on the same I2C bus, making it a versatile solution for expanding I/O capabilities in embedded systems.
