The MCP23017 device provides 16-bit, general purpose, parallel I/O expansion for I2C bus applications. This device includes high-current drive capability, low supply current and individual I/O configuration. I/O expanders provide a simple solution when additional I/Os are needed for ACPI, power switches, sensors, push buttons, LEDs and so on. The MCP23017 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.
- 16-bit remote bidirectional I/O port - I/O pins default to input
- High-speed I2C™ interface (MCP23017) - 100 kHz - 400 kHz - 1.7 MHz
- High-speed SPI interface (MCP23S17) - 10 MHz (max.)
- Three hardware address pins to allow up to eight devices on the bus
- Configurable interrupt output pins - Configurable as active-high, active-low or open-drain
- INTA and INTB can be configured to operate independently or together
- Configurable interrupt source - Interrupt-on-change from configured register defaults or pin changes
- Polarity Inversion register to configure the polarity of the input port data
- External Reset input
- Low standby current: 1 µA (max.)
- Operating voltage: - 1.8V to 5.5V @ -40°C to +85°C - 2.7V to 5.5V @ -40°C to +85°C - 4.5V to 5.5V @ -40°C to +125°C
