General description
The PCA9675 provides general purpose remote I/O expansion for most microcontroller
families via the two-line bidirectional bus (I2C-bus) and is a part of the Fast-mode Plus
family.
The PCA9675 is a drop in upgrade for the PCF8575 providing higher Fast-mode Plus
(Fm+) I2C-bus speeds (1 MHz versus 400 kHz) so that the output can support PWM
dimming of LEDs, higher I2C-bus drive (30 mA versus 3 mA) so that many more devices
can be on the bus without the need for bus buffers, higher total package sink capacity
(400 mA versus 100 mA) that supports having all 25 mA LEDs on at the same time and
more device addresses (64 versus 8) are available to allow many more devices on the
bus without address conflicts.
The device consists of a 16-bit quasi-bidirectional port and an I2C-bus interface. The
PCA9675 has a low current consumption and includes latched outputs with high current
drive capability for directly driving LEDs.
It 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) or software reset sequence initializes
the I/Os as inputs.
