MCP23017T-E/SS

The MCP23017T-E/SS is a 16-bit I/O expander with integrated address and direction registers, designed to extend the capabilities of an MCU (Microcontroller Unit). It allows for additional GPIO (General Purpose Input/Output) lines to be controlled by the MCU, enabling it to handle more inputs and outputs than its physical pin count would allow. This device is ideal for applications where the number of required IO pins exceeds the MCU's available pins.

Key Features:

• 16 bidirectional I/O pins

• Integrated address and direction registers

• Interrupt functionality for input state changes

• Programmable input polarity

• Selectable current levels for output and input pins

• Wide operating voltage range

• Supports both SPI and I2C interfaces for communication with MCU

• Low power consumption

• Available in various package types to suit different applications

Applications:

The MCP23017T-E/SS can be utilized in a broad array of applications where an extension of GPIOs is necessary, such as:

• Automotive systems requiring complex control

• Industrial automation and control

• Consumer electronics with multi-functional interfaces

• Communication systems needing additional IO for signaling • Smart home devices and IoT (Internet of Things) solutions

• Robotics and mechatronics projects

• Custom electronics development where space and pin availability are constrained
