Overview
The XRA1402IL16MTR-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 15 MHz. The device features an interrupt output capability and is housed in a QFN-16 package with surface mount installation style. It functions reliably across a temperature range of -40°C to +85°C, dissipating up to 200 mW of power while delivering an output current of 160 mA.
Feature Summary
- Provides 8-bit general-purpose input/output expansion via SPI interface
- Includes interrupt output functionality for efficient event handling
- Operates on low voltage supplies ranging from 1.65 V to 3.6 V
Applications
- General purpose I/O expansion in embedded systems
- GPIO port extension for microcontrollers using SPI communication
- Low voltage portable electronic devices requiring I/O multiplexing
Procurement Notes
Verify component authenticity through authorized channels due to obsolete status. Confirm RoHS compliance details as specified in official documentation. Check for moisture sensitivity level requirements during storage and handling. Ensure the specific suffix matches design specifications before procurement.
Selection Notes
Select this component when SPI-based I/O expansion is required in space-constrained designs. The QFN-16 package suits applications needing compact footprints. Verify that the 15 MHz SPI speed meets system timing requirements. Ensure the operating voltage aligns with the target logic levels.
Part Context
This part belongs to the XRA1402 series of I/O expanders. It shares functional similarities with other models in the family but differs in packaging and termination options. The IL16 designation indicates the QFN-16 package variant, while MTR-F specifies the tape and reel packaging format.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided data. Consult manufacturer documentation for potential cross-references or updated product line replacements.
