PCA9675D Datasheet | NXP Semiconductors

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 k Hz) so that the output can support PWM dimming of LEDs, higher I2C-bus drive (30 m A versus 3 m A) so that many more devices can be on the bus without the need for bus buffers, higher total package sink capacity (400 m A versus 100 m A) that supports having all 25 m A 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 ining data on its ports without having to municate via the I2C-bus. The internal Power-On Reset (POR) or software reset sequence initializes the I/Os as inputs. 2.
