XRA1402IL16TR-F

Overview

The XRA1402IL16TR-F is an 8-bit SPI General Purpose Input/Output (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 15 MHz. The device provides interrupt output capabilities and delivers an output current of 160 mA with a power dissipation limit of 200 mW. Designed for surface mount applications, it is housed in a QFN-16 package measuring 3 x 3 mm with a height of 0.90 mm and 0.50 mm pitch. It functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Provides eight general-purpose input/output pins accessible via a serial peripheral interface.
• Includes interrupt output functionality to signal state changes to the host processor.
• Supports low-voltage operation suitable for portable and battery-powered systems.

Applications

• Embedded systems requiring additional GPIO pins via SPI communication
• Portable electronic devices with limited pin availability on main controllers
• Industrial control interfaces needing isolated or expanded I/O handling

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status using official documentation. Check for product discontinuation notices as some sources indicate end-of-life status. Ensure packaging specifications match design requirements before procurement.

Selection Notes

Select this component when an 8-bit SPI GPIO expander is required within a 1.65 V to 3.6 V operating range. Verify that the QFN-16 package dimensions fit the PCB layout constraints. Ensure the host system supports SPI communication at frequencies up to 15 MHz. Consider thermal management if power dissipation approaches the 200 mW limit.

Part Context

This part belongs to the XRA1402 series of SPI GPIO expanders from MaxLinear. It shares functional similarities with other members like the XRA1402IG16-F but differs in packaging and termination style. The IL suffix indicates the QFN-16 package variant, while TR-F denotes tape and reel packaging for automated assembly processes.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with similar SPI GPIO expanders only after verifying electrical compatibility and pinout alignment.
