Overview
The PCA8575 provides general purpose remote I/O expansion for most microcontroller families via the two-line bidirectional I²C-bus serial clock SCL, serial data SDA.
The device consists of a 16-bit quasi-bidirectional port and an I²C-bus interface. The PCA8575 has a low current consumption and includes latched outputs with high current drive capability for directly driving LEDs.
The PCA8575 also possesses an interrupt line INT which can be connected to the interrupt logic of the microcontroller. By sending an interrupt signal on this line, the remote I/O can inform the microcontroller if there is incoming data on its ports without having to communicate via the I²C-bus. The internal Power-On Reset POR initializes the I/Os as inputs.
