Overview
The XRA1201IL24TR-F is a 16-bit I2C and 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 400 kHz. The device features open-drain outputs with a total output current capability of 160 mA and includes interrupt output functionality. It is housed in a QFN-EP-24 package suitable for surface mount installation. The component functions across an operating temperature range from -40°C to +85°C, with a maximum power dissipation of 200 mW.
Feature Summary
- Provides 16 configurable general-purpose input/output channels via I2C/SMBus interface
- Includes dedicated interrupt output pin for efficient event handling
- Supports low-voltage operation down to 1.65 V for energy-efficient designs
Applications
- Embedded systems requiring expanded GPIO capabilities
- Consumer electronics with limited microcontroller pins
- Industrial control interfaces needing reliable I/O expansion
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for end-of-life notices or product discontinuance announcements. Ensure storage conditions meet humidity sensitivity requirements to prevent damage during soldering processes.
Selection Notes
Select this component when a 16-bit I/O expansion solution is required with I2C compatibility. Consider the QFN-EP-24 package size constraints and thermal dissipation limits. Verify that the system voltage aligns with the 1.65 V to 3.6 V operating range. Evaluate interrupt line availability if real-time response is necessary for connected peripherals.
Part Context
This part belongs to the XRA1201 series of I/O expanders from MaxLinear. It shares functional similarities with other models in the family but differs in pin count and package type. The IL24 suffix indicates the specific QFN-EP-24 packaging variant. Related parts include the XRA1200 and XRA1202 series for different bit-width requirements.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with similar 16-bit I2C GPIO expanders only after verifying pinout and electrical parameter compatibility.
