I/O Expanders Microchip Technology MCP23017-E/SSVAO Overview
The MCP23017-E/SSVAO from Microchip Technology is a highly versatile I/O expander that enhances the functionality of any microcontroller-driven system. As an integral part of the I/O Expanders category, this device offers a seamless way to increase the number of input/output ports, which are crucial for handling various devices and peripherals. This product stands out by providing 16 additional I/O ports that can be individually controlled through a simple two-wire bidirectional bus (I2C). The MCP23017-E/SSVAO is a perfect solution for applications requiring additional ports without the need for upgrading the main microcontroller, thus minimizing system costs and complexity.
MCP23017-E/SSVAO Features
The MCP23017-E/SSVAO expander includes several key features that make it an essential component for expanding the capabilities of embedded systems. These features include high-speed I2C interface at 400 kHz, 16 individually configurable I/O pins, interrupt output pins for input change notification, and a hardware address pin to allow up to eight devices on the same bus. This allows for a possible expansion of up to 128 I/Os. Its robust serial interface ensures easy integration with most microcontrollers.
