XRA1201P 16-BIT I2C/SMBUS GPIO EXPANDER

The XRA1201/1201P is a 16-bit GPIO expander with an I2C/SMBus interface. After power-up, the XRA1201 has internal 100K ohm pull-up resistors on each I/O pin that can be individually enabled. The XRA1201P has the internal pull-up resistors enabled upon power-up in case it is necessary for the inputs .

XRA1201P Features

* 1.65V to 3.6V operating voltage

* 16 General Purpose I/Os (GPIOs)

* 5V tolerant inputs

* Maximum stand-by current of 1uA at +1.8V

* I2C/SMBus bus interface

* I2C clock frequency up to 400kHz

* Noise filter on SDA and SCL inputs

* Up to 32 I2C Sla
