Overview
The XRA1203IL24-F is a 16-bit I/O expander manufactured by MaxLinear, designed for serial interface applications. It operates via I2C, Serial, and SMBus protocols with a maximum clock frequency of 100 kHz. The device supports an operating supply voltage range from 1.65 V to 3.6 V and provides an interrupt output capability. It features a total output current capacity of 160 mA and a power dissipation rating of 200 mW. The component is housed in a QFN-EP-24 package suitable for SMD/SMT installation. It functions within a temperature range of -40°C to +85°C and includes humidity sensitivity characteristics.
Feature Summary
- Supports I2C, Serial, and SMBus communication interfaces
- Includes interrupt output functionality
- Provides 16 general-purpose input/output pins
Applications
- General purpose I/O expansion in embedded systems
- Interface extension for low-speed serial communication buses
- Consumer electronics requiring additional control lines
Procurement Notes
This component is officially listed as End-of-Life (EOL) by the manufacturer. Distribution channels indicate restricted availability or discontinuation status. Verification of current stock levels and final obsolescence notices through official MaxLinear channels is required before procurement planning. Alternative sourcing strategies should be considered due to the discontinued lifecycle status.
Selection Notes
Designers should verify compatibility with existing I2C or SMBus bus architectures given the 100 kHz maximum clock speed limitation. The QFN-EP-24 package requires appropriate PCB footprint design and thermal management considerations. Ensure the system voltage aligns with the 1.65 V to 3.6 V operating range. Evaluate if the 160 mA aggregate output current meets the load requirements for the intended application.
Part Context
The XRA1203IL24-F belongs to the XRA1203 series of I/O expanders from MaxLinear. This series focuses on providing serial interface connectivity for systems needing expanded GPIO capabilities. It shares similar packaging and electrical characteristics with other members like the XRA1201, though interface speeds may vary across the family.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, engineers must identify functional equivalents independently or consult manufacturer recommendations for pin-compatible or software-compatible alternatives.
