## Overview

The MCP23017-E/SP is a versatile 16-bit I/O expander designed for I2C bus applications, offering configurable input/output ports, dual interrupt pins with flexible operation modes, and a high-speed 1.7 MHz interface. It supports up to eight devices on a single bus via hardware addressing and features ultra-low standby current, making it ideal for scalable, energy-efficient embedded systems.

## Description

The MCP23017 device family provides 16-bit, general purpose parallel I/O expansion for I2C bus applications. The MCP23017-E/SP 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. The 16-bit I/O port functionally consists of two 8-bit ports (PORTA and PORTB). The MCP23017 can be configured to operate in the 8-bit or 16-bit modes via IOCON.BANK. There are two interrupt pins, INTA and INTB, that can be associated with their respective ports, or can be logically OR’ed together so that both pins will activate if either port causes an interrupt.

## Features

- 16 bit remote bidirectional I/O port, Configurable interrupt output pins, INTA and INTB can be configured to operate independently or together
- High speed I2C interface: 100 kHz, 400 kHz, 1.7 MHz, Configurable interrupt source, Polarity Inversion register to configure the polarity of the input port data
- Three hardware address pins to allow up to eight devices on the bus
- External Reset input, Low standby current: 1A max.
