Product Overview

The MCP23018-E/SP is a 16-bit I/O Expander for high speed I²C™ compatible interface. 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. The MCP23X18 consists of multiple 8-bit configuration registers for input, output and polarity selection. The system master enables 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 8-bit ports (PORTA and PORTB).
  • Low standby current as low as 1µA
  • High-speed I²C™ interface up to 3.4MHz
  • Single hardware address pin, voltage input to allow up to eight devices on the bus
  • Configurable interrupt output pins - Configurable as active-high, active-low or open-drain
  • 1µA Typical low standby current
