Information

The MCP23X18 device provides 16-bit, general purpose parallel I/O expansion for I2C bus or SPI applications. The two devices differ only in the serial interface. MCP23018 - I2C interface MCP23S18 - SPI interface The MCP23X18 consists of multiple 8-bit configuration registers for input, output and polarity selection. The system master can enable the I/Os as either inputs or outputs by writing the I/O configuration bits. The data for each input or output is kept in the corresponding input or output register. The polarity of the input port register can be inverted with the polarity inversion register. All registers can be read by the system master. The 16-bit I/O port functionally consists of two (2) 8-bit ports (PORTA and PORTB). The MCP23X18 can be configured to operate in 8-bit mode or 16-bit mode via IOCON.BANK.

Key Features

  • 16-bit remote bidirectional I/O port: - I/O pins default to input
  • Open-drain outputs: - 5.5V tolerant - 25 mA sink capable (per pin) - 400 mA total - 100 kHz - 400 kHz - 3.4 MHz
  • High-speed SPI interface: (MCP23S18) - 10 MHz: 2.7V ≤ VDD ≤ 5.5V - Voltage input to allow up to eight devices on the bus
  • Configurable interrupt output pins: - Configurable as active-high, active-low or open-drain
  • Configurable interrupt source: - Interrupt-on-change from configured defaults or pin change
  • Polarity inversion register to configure the polarity of the input port data
  • External reset input
  • Low standby current: - 1 µA (-40°C ≤ TA ≤ +85°C) - 6 µA (+85°C ≤ TA ≤ +125°C)
  • Operating voltage: - 1.8V to 5.5V
