Overview
The XRA1203IG24-F is a 16-bit I2C/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 100 kHz. The device features an interrupt output capability and provides a total output current of 160 mA with a power dissipation limit of 200 mW. It is housed in a QFN-EP-24 package, suitable for surface mount installation, and functions reliably across an industrial temperature range from -40°C to +85°C.
Feature Summary
- Provides 16 general-purpose input/output pins accessible via standard I2C or SMBus interfaces.
- Includes an interrupt output pin to signal state changes to the host processor without continuous polling.
- Supports low-voltage operation compatible with modern embedded systems requiring 1.65 V to 3.6 V supplies.
Applications
- Embedded systems requiring additional digital I/O lines for sensor interfacing
- Consumer electronics utilizing space-constrained PCB layouts
- Industrial control modules needing reliable GPIO expansion under varying temperatures
Procurement Notes
Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status directly with the manufacturer or certified distributors. Ensure storage conditions respect humidity sensitivity levels specified in the datasheet to prevent moisture-induced damage during soldering processes.
Selection Notes
Select this component when a high-density 16-bit expansion is required on an I2C bus. Compare against the XRA1201 series if higher speed (400 kHz) or reel packaging is needed. Verify that the QFN-24 footprint matches the target PCB design constraints and thermal requirements.
Part Context
This part belongs to the XRA1203 family of I/O expanders from MaxLinear. It shares functional similarities with other members like the XRA1201 but differs in interface speed and packaging options. The IG24 suffix indicates the specific TSSOP/QFN variant and lead-free finish configuration defined by the manufacturer.
Replacement Considerations
Direct substitutes include the XRA1201IL24-F for similar functionality with different speed ratings. Cross-reference pinouts carefully as package variations may exist between TSSOP and QFN forms within the same logical device family.
