XRA1206IG16TR-F

Overview

The XRA1206IG16TR-F is an 8-bit I/O expander manufactured by MaxLinear, designed to expand system input/output capabilities via an I2C or SMBus interface. It operates within a supply voltage range of 1.65 V to 3.6 V and supports a maximum clock frequency of 400 kHz. The device features interrupt output functionality and is housed in a TSSOP-16 package suitable for surface mount installation. It functions as a serial interface component within the broader category of interface integrated circuits.

Feature Summary

• Provides eight general-purpose digital input and output lines for system expansion
• Interfaces with host processors using standard I2C or SMBus communication protocols
• Includes dedicated interrupt output capability to signal data availability or status changes

Applications

• Embedded systems requiring additional GPIO connectivity
• Industrial control modules needing remote I/O expansion
• Consumer electronics utilizing I2C/SMBus architectures

Procurement Notes

Verify current manufacturing status as this component may be obsolete. Confirm compatibility with existing I2C or SMBbus bus speeds and voltage levels before integration. Check for authorized distributors offering valid stock, as availability is restricted. Ensure replacement parts meet identical electrical specifications and pinout requirements for seamless substitution in existing designs.

Selection Notes

Select this component when an 8-bit expansion is required on an I2C or SMBus bus. Consider the TSSOP-16 package size for space-constrained applications. Verify that the operating voltage range aligns with the system's power supply rails. Evaluate the need for interrupt-driven operations versus polling methods based on system latency requirements.

Part Context

This part belongs to the XRA1200 series of I/O expanders from MaxLinear. It serves as a bridge between microcontrollers and peripheral devices, allowing for flexible system configuration without consuming additional processor pins. The series focuses on low-power operation and reliable serial communication for embedded environments.

Replacement Considerations

Check for direct substitutes within the XRA1200 family. Verify pin-to-pin compatibility if replacing in existing PCB layouts. Ensure the substitute supports the same I2C/SMBus protocol and voltage ranges.
