The XRA1405 is an 16-bit GPIO expander with an SPI interface. After power-up, the XRA1405 has internal 100K ohm pull-up resistors on each I/O pin that can be individually enabled.

In addition, the GPIOs on the XRA1405 can individually be controlled and configured. As outputs, the GPIOs can be outputs that are high, low or in three-state mode. The three-state mode feature is useful for 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 programmed to generate an interrupt on the rising edge, falling edge or on both edges. The interrupt can be cleared if the input changes back to its original state or by reading the current state of the inputs.

The XRA1405 is available in 24-pin QFN and 24-pin TSSOP packages.

Distribution Date Description File
07/17/2023 In 2023, MaxLinear will be converting all shipping labels for the parts noted from an EXAR format to MaxLinear’s label. During this transition customers may receive either label. This change affects only shipping and packing labels. This change will not affect the part number, part marking, manufacturing process or manufacturing sites. Only work in progress material will be converted. Existing inventory from MaxLinear’s warehouse, channel sales, distributor, and such, will not be converted. Hence, customers may experience receiving mixed shipments with both Exar and MaxLinear labels for some period until existing inventory of old labels is eventually cleared out. Situation is product to product with no predictable way to determine when all old labels will be exhausted. No change to product form, fit, function and reliability. ADDENDUM A: Fixed MBB label logo for DX204001 to MaxLinear logo. ADDENDUM B: Replaced ‘All other affected products outer box label’ with clearer pictures. Corrected Date Issued (from original PCN) issue date +90 days to August 30, 2023.
