XRA1402IL16-F

Overview

The XRA1402IL16-F is an 8-bit SPI GPIO expander manufactured by MaxLinear. It operates within a supply voltage range of 1.65 V to 3.6 V and supports a maximum clock frequency of 26 MHz. The device provides 160 mA output current capability and dissipates up to 200 mW of power. It functions reliably between -40°C and +85°C. The component is housed in a QFN-16 package with dimensions of 3 mm x 3 mm and a height of 0.90 mm.

Feature Summary

• Supports high-speed serial peripheral interface communication for efficient data transfer
• Provides interrupt output functionality for event-driven system responses
• Features open-drain outputs suitable for various logic level interfacing

Applications

• General purpose input/output expansion in embedded systems
• Interface extension for microcontrollers requiring additional digital pins
• Consumer electronics devices needing low-pin-count I/O management

Procurement Notes

Verify the specific suffix and package variant against official datasheets before integration, as manufacturing sources may vary. Confirm end-of-life status and discontinuation notifications from the manufacturer to ensure long-term supply chain stability. Cross-reference RoHS compliance details directly with the latest regulatory documentation provided by MaxLinear.

Selection Notes

Select this component when an 8-bit parallel port expansion via SPI is required within a compact QFN footprint. Ensure the host controller supports the specified 26 MHz clock speed and that the operating voltage aligns with the 1.65 V to 3.6 V range. Consider the thermal dissipation limits and ambient temperature requirements for the final enclosure design.

Part Context

This part belongs to the XRA1402 series of I/O expanders from MaxLinear. It shares functional similarities with other models in the family but differs in package type and specific pinout configuration. The IL16 suffix denotes the QFN-16 packaging option, distinguishing it from TSSOP or other available variants within the same product line.

Replacement Considerations

Check for direct substitutes within the XRA1402 series that offer compatible pinouts. Verify if alternative packages like TSSOP-16 provide necessary mechanical fit without electrical modification. Consult official cross-reference lists for any discontinued equivalents.
