XRA1200PIG16-F

Overview

The XRA1200PIG16-F is an 8-bit I2C/SMBus GPIO expander manufactured by MaxLinear. It operates within a supply voltage range of 1.65V to 3.6V and supports clock frequencies up to 400kHz. The device features 5V tolerant inputs, open-drain active low interrupt output, and 3kV HBM ESD protection. It is housed in a 16-pin TSSOP package with an operating temperature range of -40°C to +85°C. Internal pull-up resistors are enabled upon power-up for the 'P' variant.

Feature Summary

• Pin and software compatible with CAT9534, CAT9554, PCA9534, and PCA9554 devices
• Individually programmable inputs with internal pull-ups, polarity inversion, and edge-selectable interrupts
• Individually programmable outputs with level control and three-state mode capability

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for End-of-Life notices. Ensure storage conditions meet moisture sensitivity requirements prior to assembly.

Selection Notes

Select this model when pin compatibility with existing PCA9534/PCA9554 designs is required. Choose the 'P' suffix variant if internal pull-up resistors must be enabled automatically after power-up. Verify that the 16-pin TSSOP package fits the target PCB footprint.

Part Context

This component belongs to the XRA1200 series of I/O expanders. It serves as a drop-in replacement for legacy Exar and National Semiconductor GPIO expanders. The 'P' designation specifically indicates the inclusion of enabled internal pull-up resistors on all GPIO pins upon reset.

Replacement Considerations

Direct pin-compatible substitutes include CAT9534, CAT9554, PCA9534, and PCA9554. Verify register mapping and interrupt behavior differences before swapping.
