XRA1200IG16TR-F

Overview

The XRA1200IG16TR-F is an 8-bit I2C/SMBus GPIO expander manufactured by MaxLinear, formerly Exar Corporation. It operates within a supply voltage range of 1.65V to 3.6V and supports I2C clock frequencies up to 400kHz. The device features individually programmable inputs with internal pull-up resistors and polarity inversion, as well as outputs capable of high, low, or three-state modes. It includes an open-drain active-low interrupt output configurable for rising, falling, or both edges. The component is housed in a 16-pin TSSOP package and functions across an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports I2C and SMBus interfaces with up to 32 selectable slave addresses via hardware pins.
• Provides individually programmable GPIO inputs with internal pull-ups and polarity inversion options.
• Features open-drain active-low interrupt output with configurable edge detection and input filtering.

Applications

• Personal Digital Assistants (PDA)
• Cellular Phones and Data Devices
• Battery-Operated Devices
• Global Positioning System (GPS) Modules
• Bluetooth Modules

Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when sourcing this part number. Confirm that the 'I' designation corresponds to the TSSOP-16 package variant rather than the QFN-16 option. Ensure compatibility with existing I2C bus addressing schemes, as multiple address configurations are available through the A0-A2 pins. Check for RoHS compliance status if required by local regulations.

Selection Notes

Select the XRA1200IG16TR-F when an 8-bit GPIO expansion solution is needed with I2C connectivity. Choose this model over the XRA1200P variant if internal pull-up resistors must be disabled by default after power-up. Consider the TSSOP-16 package for surface mount applications requiring this specific footprint. Verify that the 5V tolerant inputs meet the system's logic level requirements.

Part Context

This component belongs to the XRA1200 series of 8-bit I/O expanders from MaxLinear. It is pin and software compatible with the CAT9534, PCA9534, CAT9554, and PCA9554 devices. The 'IG16' suffix specifically denotes the TSSOP-16 package type, distinguishing it from the 'IL16' QFN-16 variant within the same functional family.

Replacement Considerations

Pin and software compatible replacements include CAT9534, PCA9534, CAT9554, and PCA9554. Note that the XRA1200P variant differs only in default internal pull-up resistor states. Verify package dimensions match the TSSOP-16 form factor when substituting.
