What Stands Out

16-bit Expansion
The MCP23017 allows for easy expansion of microcontroller I/O ports by 16 additional pins, enhancing project capabilities without the need for multiple chips.
I2C Interface
Designed with an I2C communication protocol, it facilitates simple connections and multiple device handling on a single bus, making it ideal for complex applications.
Flexible Configuration
Configurable for input or output modes per pin, the MCP23017 accommodates diverse project requirements, providing versatility for varied electronics applications.

有疑問？ 和我們聊天

客戶問答

  • 問題: How to set I²C address?

    Answer: Configure A0/A1/A2 pins (e.g., all grounded = address 0x20).
  • 問題: How to enable pull-up resistors?

    Answer: Set the GPPU register bit (e.g., write 0xFF to GPPUA for port A pull-up).
  • 問題: Can it drive relays directly?

    Answer: Yes, it can drive relays directly with a 25mA pin output but add buffers for high-power loads.
