XRA1203IG24TR-F

Overview

The XRA1203IG24TR-F is a 16-bit I/O expander manufactured by MaxLinear, designed for serial interface expansion. It operates via I2C and SMBus protocols with a maximum clock frequency of 100 kHz. The device supports a 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 surface mount technology. It functions within a temperature range of -40°C to +85°C and includes humidity sensitivity characteristics.

Feature Summary

• Provides 16 general-purpose input/output pins accessible through standard I2C and SMBus serial interfaces.
• Includes an interrupt output pin to signal state changes on the GPIO lines without continuous polling.
• Supports low-voltage operation ranging from 1.65 V to 3.6 V for compatibility with various logic levels.

Applications

• Embedded systems requiring additional digital I/O ports via serial buses
• Consumer electronics utilizing I2C or SMBus communication standards
• Industrial control modules needing extended GPIO capabilities in compact packages

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing this part number. Confirm the manufacturer designation remains MaxLinear, Inc., as corporate structures may affect documentation sources. Check for End-of-Life status or Product Change Notices prior to final design approval. Ensure the QFN-EP-24 footprint matches the target PCB layout requirements exactly.

Selection Notes

Select this component when a 16-bit expansion is required over I2C or SMBus interfaces. Compare against the XRA1203IL24-F variant if tray packaging is preferred over reel packaging. Verify that the 100 kHz maximum clock speed meets the system timing requirements. Ensure the operating voltage range aligns with the host controller's logic levels.

Part Context

This part belongs to the XRA1203 series of I/O expanders from MaxLinear. It shares functional similarities with the XRA1201IL24TR-F but differs in packaging and potentially clock speed specifications. The series is categorized under Interface ICs, specifically I/O Expanders. It serves as a solution for increasing pin counts in space-constrained designs using standard serial protocols.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided data. Evaluate the XRA1203IL24-F for potential pin-compatible alternatives if packaging differences are acceptable. Consult official MaxLinear documentation for any discontinued product replacement recommendations.
