XRA1201PIL24TR-F

Overview

The XRA1201PIL24TR-F is a 16-bit I/O expander manufactured by MaxLinear, Inc., designed for serial interface applications. It operates via I2C and SMBus protocols within a supply voltage range of 1.65 V to 3.6 V. The device features an interrupt output capability and supports clock frequencies up to 400 kHz. It is housed in a QFN-EP-24 package suitable for surface mount technology. The component functions as a general-purpose input/output extender with open-drain outputs capable of sourcing 160 mA total current. It includes ESD protection rated at 3 kV and dissipates up to 200 mW of power.

Feature Summary

• Provides 16 configurable general-purpose I/O pins accessible through standard I2C and SMBus serial interfaces.
• Includes an interrupt output pin that signals state changes on inputs or configuration updates to the host processor.
• Features open-drain output structures allowing flexible voltage level interfacing across the supported supply range.

Applications

• Expanding GPIO availability in embedded systems with limited controller pins.
• Interface extension for IoT devices requiring low-power I/O management.
• Control logic expansion in industrial automation modules using SMBus communication.

Procurement Notes

Verify the specific suffix 'P' against official MaxLinear documentation to confirm if it denotes a specific tape-and-reel variant or packaging distinction compared to the standard XRA1201IL24TR-F. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to assembly planning. Ensure the supplier provides traceability data matching the manufacturer's lot codes.

Selection Notes

Select this component when a system requires multiple digital inputs or outputs controlled via I2C or SMBus without dedicated parallel ports. Consider the 160 mA total sink/source limit for load requirements. Verify that the target application environment remains within the -40°C to +85°C operating temperature range. Ensure the host controller supports the required clock speeds up to 400 kHz.

Part Context

This part belongs to the XRA1201 series of I/O expanders from MaxLinear. It shares functional similarities with other members like the XRA1203 but differs in package type and specific interface support. The series is designed to replace traditional parallel I/O solutions in space-constrained designs. It complements MaxLinear's broader portfolio of interface and power management ICs.

Replacement Considerations

Publicly confirmed direct substitutes are not available in the provided source material. The XRA1201IL24TR-F appears to be the primary commercial variant; verify if the 'P' suffix indicates a non-functional packaging difference. Cross-reference pinouts and electrical characteristics carefully before substituting with generic I2C expanders.
