XRA1404 Datasheet (MaxLinear) - 8-Bit SPI GPIO Expander

XRA1404, 8-Bit SPI GPIO Expander

The XRA1404 is an 8-bit GPIO expander with an SPI interface.

After power-up, the XRA1404 has internal 100K ohm pull-up resistors on each I/O pin that can be individually enabled.

In addition, the GPIOs on the XRA1404 can individually be controlled and configured.

As outputs, the GPIOs can be outputs
