Overview
The XRA1405IL24TR-F is a 16-bit Serial Peripheral Interface (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 clock frequencies up to 26 MHz. The device features open-drain outputs capable of sourcing 160 mA, with an interrupt output capability for efficient host notification. It is housed in a QFN-24 package and functions reliably across an industrial temperature range from -40°C to +85°C.
Feature Summary
- Provides 16 bidirectional I/O channels via SPI interface
- Includes dedicated interrupt output pin for event signaling
- Supports open-drain output configuration with high current drive
Applications
- Embedded systems requiring additional GPIO pins
- Industrial control panels with limited microcontroller ports
- Consumer electronics with space-constrained PCB layouts
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level prior to soldering. Check for end-of-life notifications as discontinuation may affect long-term availability. Ensure packaging specifications match production requirements.
Selection Notes
Select this component when 16 digital I/O lines are required alongside SPI connectivity. Consider the QFN-24 footprint for board space optimization. Verify that the host controller supports the necessary SPI modes and interrupt handling capabilities. Evaluate power consumption against system battery constraints given the operating voltage range.
Part Context
This part belongs to the XRA1405 series of GPIO expanders. It shares functional similarities with other MaxLinear interface ICs but is distinct in its 16-bit capacity and specific package type. It complements the broader portfolio of serial interface solutions designed for low-power embedded applications.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult MaxLinear technical support for potential cross-references or updated product line recommendations.
