XRA1206IG16-F

Overview

The XRA1206IG16-F is an 8-bit I2C and SMBus 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 400 kHz. The device features open-drain outputs with configurable pull-up resistors and includes an interrupt output for efficient host notification. It is housed in a 16-pin TSSOP package and functions across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Supports standard I2C and SMBus communication protocols
• Provides eight general-purpose input/output pins
• Includes interrupt output capability for event-driven operation

Applications

• Embedded systems requiring additional GPIO ports
• Industrial control interfaces
• Consumer electronics peripheral expansion

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm RoHS compliance status via the manufacturer datasheet before integration. Check for end-of-life notices or obsolescence warnings to ensure long-term supply stability for production runs.

Selection Notes

Select this component when an 8-bit I/O expander with I2C/SMBus interface is required. Ensure the system voltage aligns with the 1.65 V to 3.6 V operating range. Verify that the TSSOP-16 package fits the PCB layout constraints and that the 400 kHz bus speed meets application timing requirements.

Part Context

This part belongs to the XRA1200 series of I/O expanders, which are designed for low-voltage applications. It serves as a pin-expansion solution for microcontrollers lacking sufficient GPIO lines. The series typically includes variants with different bit widths and package options to suit various design needs.

Replacement Considerations

Compatible alternatives include the XRA1200IG16-F and XRA1201IG24-F. Verify pin compatibility and register mapping before substitution. Ensure the replacement part supports the same I2C address configuration and interrupt logic.
