Specification

Product Name: MCP23017 16-bit I/O Expander with I2C Interface
Key Features:
<ol>
<li>
I2C Interface: The MCP23017 provides a high-performance, only two-wire serial interface (I2C) for connection to a microcontroller, reducing the need for additional data lines compared to conventional parallel I/O interfaces. This feature facilitates a cleaner and more space-optimized design in your electronic projects.
</li>
<li>
16 General-Purpose Input/Output Pins: Each MCP23017 chip features 16 pinup/down edges capable of functioning as general-purpose input/output (GPIO) pins. These pins offer independent control of each pin's direction (Input/Output), and can be configured as open-drain or interrupt-on-change outputs for flexibility in a wide range of applications.
</li>
<li>
Latching Inputs and Active-Low Open Drain Outputs: The MCP23017's latching inputs ensure that the input state data is retained even when the microcontroller is not supplying power to the I/O expander, providing a stable reference for your design. The active-low open drain outputs, on the other hand, offer greater control, allowing your microcontroller to release (low) or pull up (high) each output, reducing power consumption and controlling multiple outputs simultaneously.
</li>
<li>
On-chip 8-bit Address Select Pins: The MCP23017 features on-chip 8-bit address select pins that allow cascading multiple MCP23017 devices, enabling you to expand the number of available I/O pins without complicating your addressing scheme or adding additional microcontrollers.
</li>
<li>
Internal 10-bit Analog-to-Digital Converter (ADC): Each MCP23017 chip contains an internal 10-bit analog-to-digital converter (ADC), enabling you to measure and convert over 1024 analog voltage levels to digital values. This allows for the integration of electronic sensors in your projects without the need for an additional separate ADC device.
</li>
<li>
Programmable Internal Pull-ups: The MCP23017 offers programmable internal pull-ups on the input pins, making it much easier to interface with various sensors and external devices with different voltage levels and impedances.
</li>
<li>
On-chip Overvoltage Protection: The MCP23017 includes built-in overvoltage protection, ensuring the device's long-term reliability by guarding against voltage spikes or transients that may occur due to dynamic conditions in your project.
</li>
<li>
Peripheral Functions: In addition to the main GPIOs, the MCP23017 offers a range of useful peripheral functions, including an alarm output, software-writable polarity selectable open-drain power-good output, and a configurable internally pull-up programmable input (for sensor interfacing), making it a versatile choice for your IoT, automation, and other electronics projects.
</li>
<li>
Compact Size for Reduced PCB Footprint: The MCP23017's small form factor makes it an ideal addition to space-constrained projects, allowing you to pack more functionality into your designs without incurring the added costs and complications of multiple components.
</li>
<li>
Approved for Automotive Applications: The MCP23017 is AEC-Q100 qualified, ensuring that the device is suitable for use in automotive and harsh environments due to its enhanced reliability and temperate tolerance.
