MCP23S17-E/SS Frequently Asked Questions (FAQ)

  • The maximum frequency of the SPI interface is 10 MHz.

  • The MCP23S17 is a 1.8V to 5.5V device, but for 3.3V operation, ensure the VDD pin is connected to a 3.3V power supply and the VREF pin is connected to a 3.3V reference voltage.

  • Yes, the MCP23S17 is 5V tolerant, but ensure the VDD pin is connected to a 3.3V power supply and the VREF pin is connected to a 3.3V reference voltage.

  • The MCP23S17 can be reset by pulling the RESET pin low for at least 100 ns.

  • The WP (Write Protect) pin is used to prevent accidental changes to the configuration registers. When WP is low, the configuration registers are write-protected.
