Overview
The XRA1200PIG16TR-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 I2C clock frequencies up to 400kHz. The device features 5V tolerant inputs, individually programmable internal pull-up resistors, and polarity inversion capabilities. It includes an open-drain active low interrupt output with configurable edge detection. 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 A0-A2 pins.
- Features individually programmable outputs with three-state control for remote device power management.
- Includes configurable interrupt generation on rising or falling edges with input filtering.
Applications
- Personal Digital Assistants (PDA)
- Cellular Phones and Data Devices
- Battery-Operated Devices
Procurement Notes
Verify the specific suffix 'TR' indicates tape and reel packaging when sourcing this component. Confirm that the 'P' designation corresponds to the variant with internal pull-up resistors enabled upon power-up. Ensure compatibility with existing I2C bus addressing schemes before procurement.
Selection Notes
Select the XRA1200PIG16TR-F over the standard XRA1200IG16TR-F if internal pull-up resistors are required to be enabled immediately after power-up. This variant ensures inputs remain in a known state without external components. Verify that the 16-pin TSSOP package meets the board layout requirements.
Part Context
This component belongs to the XRA1200/1200P series of 8-bit GPIO expanders. It serves as a pin and software compatible replacement for devices such as the CAT9534, PCA9534, CAT9554, and PCA9554. The 'P' suffix specifically denotes the inclusion of internal pull-up resistors enabled at startup.
Replacement Considerations
Pin and software compatible replacements include CAT9534, PCA9534, CAT9554, PCA9554, PCA9554A, and TCA9554A. Verify that the substitute part matches the specific 'P' variant requirement for enabled internal pull-ups if applicable.
