DEVICE OVERVIEW
The MCP23016 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 MCP23016 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 read register
can be inverted with the polarity inversion register (see
“Input
Polarity
Registers”).
All
registers can be read by the system master.
The open-drain interrupt output is activated when any
input state differs from its corresponding input port
register state. This is used to indicate to the system
master that an input state has changed. The interrupt
capture register captures port value at this time. The
Power-on Reset sets the registers to their default val-
ues and initializes the device state machine.
Three device inputs (A0 - A2) determine the I2C
address and allow up to eight I/O expander devices to
share the same I2C bus.
