XRA1404 8-BIT SPI GPIO EXPANDER

XRA1404 Description

XRA1404 8-BIT SPI GPIO EXPANDER WITH INTEGRATED LEVEL SHIFTERS SEPTEMBER 2011 REV.1.0.0 GENERAL .
The XRA1404 is an 8-bit GPIO expander with an SPI interface.

XRA1404 Features

* 1.65V to 3.6V operating voltage
* Integrated level shifters
* 8 General Purpose I/Os (GPIOs)
* 5V tolerant inputs
* Maximum stand-by current of 1uA at +1.8V
* SPI bus interface
* SPI Clock Frequency up to 26MHz
* Individually programmable

XRA1404 Applications

* where the power is removed from the remote devices, but they may still be connected to the GPIO expander. As inputs, the internal pull-up resistors can be enabled or disabled and the input polarity can be inverted. The interrupt can be programmed for different behaviors. The interrupts can be progra
