XRA1202IL16MTR-F

Overview

The XRA1202IL16MTR-F is an 8-bit I/O expander from MaxLinear, designed to expand GPIO capabilities via I2C and SMBus interfaces. It operates within a supply voltage range of 1.65V to 3.6V and supports clock frequencies up to 400 kHz. The device features interrupt output functionality and functions across a temperature range of -40°C to +85°C. Packaged in a 16-QFN (3x3) format, it provides efficient serial interface expansion for embedded applications requiring additional digital input/output lines.

Feature Summary

• Provides 8-bit general-purpose input/output expansion through standard I2C and SMBus protocols
• Includes dedicated interrupt output capability for efficient event-driven system communication
• Operates with low-voltage power supplies ranging from 1.65V to 3.6V for flexible integration

Applications

• Embedded systems requiring additional GPIO control
• Consumer electronics with limited pin availability
• Industrial control modules needing interface expansion

Procurement Notes

Verify the specific suffix MTR-F against official MaxLinear documentation to confirm tape-and-reel packaging and exact variant specifications. Ensure compatibility with your target I2C/SMBus bus speeds and voltage levels before procurement. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when an I2C or SMBus interface is preferred over SPI for GPIO expansion. It is suitable for designs requiring interrupt-driven I/O handling rather than polling. Consider the 16-QFN package size constraints and thermal requirements during PCB layout. Verify that the host controller supports the necessary clock frequencies and address configurations for reliable operation.

Part Context

This device belongs to the XRA series of I/O expanders from MaxLinear, focusing on serial interface solutions. It complements other products like the XRA1404 (SPI-based) and XRA1200 (TSSOP package) by offering a compact QFN form factor with I2C/SMBus connectivity. The series targets applications needing scalable digital I/O management in space-constrained environments.

Replacement Considerations

The XRA1202IL16TR-F may serve as a functional substitute if packaging differences are acceptable. Check datasheets for pinout compatibility and electrical parameter alignment. No direct cross-model replacements are explicitly confirmed in public data; verify interface protocol support before substitution.
