    常見問題解答

    What is MCP23017-E/ML?

    The MCP23017-E/ML is a 16-bit I/O expander with I2C interface designed by Microchip Technology. It provides additional digital input/output pins to a microcontroller using only two wires (I2C communication), making it ideal for expanding the I/O capabilities of microcontroller-based systems.

    How Does MCP23017-E/ML Work?

    The MCP23017-E/ML works by communicating with a microcontroller through the I2C serial interface. It can be configured to operate in input or output mode for each of its 16 GPIO pins. The device can be addressed and controlled to read digital input states or set digital output states, effectively expanding the I/O capacity of the host microcontroller.

    How Many Pins does MCP23017-E/ML have and What are the Functions of the Pinout Configuration?

    The MCP23017-E/ML is housed in a 28-pin SSOP (Shrink Small Outline Package) package. The pinout configuration includes:

    • VDD: Power supply pin.
    • GND: Ground pin.
    • A0, A1, A2: Address selection pins for I2C communication.
    • SCL: Serial Clock for I2C communication.
    • SDA: Serial Data for I2C communication.
    • INTA, INTB: Interrupt pins.
    • GP0-GP7: General Purpose I/O pins (Port A).
    • GP8-GP15: General Purpose I/O pins (Port B).

    What are the Pros and Cons of MCP23017-E/ML?

    Pros:

    • Expand I/O Capability: Allows for easy expansion of digital I/O pins for microcontrollers.
    • I2C Interface: Simple 2-wire serial interface for communication with the host microcontroller.
    • Programmable Input/Output: Can configure each port pin individually as input or output.
    • Interrupt Support: Provides interrupt pins for efficient I/O monitoring.
    • Low Power Consumption: Operates with low power consumption, suitable for battery-powered applications.

    Cons:

    • Speed Limitation: I2C communication may have limitations in high-speed applications.
    • Complexity: Requires understanding of I2C protocol and address configurations for proper operation.
    • Additional Address Pins: May need additional pins for address selection in multi-device applications.

    Are There Any Equivalents/Alternatives to MCP23017-E/ML for Recommendation?

    • The PCF8574 from Texas Instruments is a similar I2C I/O expander with 8 GPIO pins.
    • Alternatives to the MCP23017-E/ML include the SX1509 from Semtech and the MAX7311 from Maxim Integrated.
