Product Overview

The MCP23016-I/SO is a 16-bit I²C™ I/O Expander provides 16-bit general purpose, parallel I/O expansion for I²C™ compatible bus applications. It includes high-current drive capability, low supply current and individual I/O configuration. I/O expander provides a simple solution when additional I/Os are needed for ACPI, power switches, sensors, push buttons, LEDs and so on. The MCP23016 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 read register can be inverted with the polarity inversion register. All registers can be read by the system master.
  • 16-bit I/O port Expander with interrupt
  • 3 Hardware address pins allow user to use up to 8 of these devices on the same I²C/SMBus
  • 25mA source/sink capability per I/O
  • I²C and SMBus compatible interface (0 to 400kHz clock frequency)
  • 16 programmable bi-directional I/Os compatible with most processors
  • Outputs can directly drive LEDs (source and sink current 25mA)
  • Polarity inversion register to configure the polarity of the input port data
  • Internal power on reset (POR)
  • Open-drain interrupt output activated when input changes state
  • Low supply current
