Features & Applications
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. MCP23S18 is available in the following packages: 28-pin PDIP (300 mil,)28-pin SOIC (300 mil), 24-pin QFN (4x4)
Features:
- 16-bit remote bidirectional I/O port
- Open-drain outputs:
- 5.5 V tolerant
- 25 mA sink capable
- 400 mA total current out
- High-speed SPI™ interface up to 10 MHz
- Configurable interrupt output pins: active-high, active-low or open-drain
- Low standby current:1 μA (typ.)
