Overview
The XRA1200PIL16TR-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 open-drain active low interrupt output, 5V tolerant inputs, and 3kV HBM ESD protection. It utilizes a 16-pin QFN package with an exposed thermal pad for improved thermal conductivity. Internal pull-up resistors are enabled upon power-up for the 'P' variant, ensuring known input states.
Feature Summary
- Pin and software compatible with CAT9534, CAT9554, PCA9534, and PCA9554
- Individually programmable inputs with internal pull-ups and polarity inversion
- Configurable interrupt generation on rising or falling edges
Applications
- Personal Digital Assistants (PDA)
- Cellular Phones/Data Devices
- Battery-Operated Devices
Procurement Notes
Verify component authenticity through authorized distributors or certified suppliers. Confirm RoHS compliance status and check for moisture sensitivity labeling prior to soldering. Ensure storage conditions meet specified humidity limits to prevent package damage during handling and assembly processes.
Selection Notes
Select this model when internal pull-up resistors must be active immediately after power-up. Verify that the 16-pin QFN footprint matches the PCB layout requirements. Ensure the system design accommodates the exposed thermal pad connection to ground for optimal heat dissipation and mechanical stability.
Part Context
This component belongs to the XRA1200/1200P series of 8-bit I/O expanders. It serves as an enhanced version of earlier models, offering improved interrupt capabilities and configurable input/output states. The 'P' suffix specifically denotes devices with permanently enabled internal pull-up resistors upon reset.
Replacement Considerations
Compatible replacements include CAT9534, CAT9554, PCA9534, and PCA9554 due to pin and software compatibility. Verify register mapping and interrupt behavior differences before substitution.
