XRA1200P Description

The XRA1200/1200P is an 8-bit GPIO expander with an I2C/SMBus interface. After power-up, the XRA1200 has internal 100K ohm pull-up resistors on each I/O pin that can be individually enabled. The XRA1200P have the internal pull-up resistors enabled upon power-up in case it is necessary for the inputs to be in a known state.
