Description

Microchip Technology's MCP23017-E/SO I/O Expander

The MCP23017-E/SO by Microchip Technology is a robust, high-performance 16-bit I/O expander that operates via an I²C-compatible serial interface. This versatile component is housed in a sleek SOIC-28 package and is designed to provide a simple solution for expanding the number of I/O pins available to a microcontroller or microprocessor system. The MCP23017-E/SO is perfect for applications where additional I/Os are necessary but board space is limited or when minimizing the number of pins on a microcontroller is a priority.

With its two independent 8-bit I/O ports (Port A and Port B), the MCP23017-E/SO can be configured to operate in 8-bit, 16-bit, or mixed modes, providing flexibility for a variety of design requirements. Each port can be independently set as an input or output, allowing for a diverse range of applications such as button interfacing, LED driving, and more.

The device features an interrupt output that can be configured to reflect a change in state on the input pins, which is invaluable for applications that require immediate attention from the host microcontroller. Additionally, the MCP23017-E/SO offers polarity inversion registers that allow users to invert the polarity of the input port data without affecting the actual data on the port.

Integration with various microcontrollers is made seamless thanks to the MCP23017-E/SO's support for multiple I²C addresses, enabling the connection of up to eight devices on the same bus without address conflicts. This capability is essential for complex systems that require a large number of I/O expansions. The device operates over a wide voltage range, typically from 1.8V to 5.5V, making it suitable for both low-voltage and standard-voltage applications.

Overall, the MCP23017-E/SO is a highly adaptable and efficient solution for system designers looking to increase the I/O capabilities of their projects without undergoing a major redesign. Its ease of use, combined with Microchip's reputation for reliability, makes it an excellent choice for expanding the functionality of any embedded system.
