XRA1201PIG24TR-F

Overview

The XRA1201PIG24TR-F is a 16-bit I/O expander manufactured by MaxLinear, belonging to the XRA1201 series. It interfaces via I2C, Serial, and SMBus protocols with a maximum clock frequency of 400 kHz. The device operates on a supply voltage ranging from 1.65 V to 3.6 V and supports an output current of 160 mA. It features open-drain outputs, interrupt capabilities, and ESD protection rated at 3 kV. Designed for surface mount applications in a QFN-EP-24 package, it functions within a temperature range of -40°C to +85°C.

Feature Summary

• Provides 16 general-purpose input/output pins accessible through standard I2C, Serial, or SMBus communication interfaces.
• Includes dedicated interrupt output functionality to signal state changes to the host processor without continuous polling.
• Integrates electrostatic discharge protection rated at 3 kV to enhance component reliability during handling and operation.

Applications

• Embedded systems requiring expanded GPIO capabilities for sensor integration or control logic
• Portable consumer electronics utilizing low-voltage power domains
• Industrial control modules operating within extended temperature environments

Procurement Notes

Verify the specific suffix 'PIG' against official MaxLinear documentation to confirm pinout and electrical characteristics, as suffixes often denote package variations or tape-and-reel specifications. Confirm RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Ensure the source provides valid traceability for this discontinued or limited-supply component.

Selection Notes

Select this component when a system requires multiple digital inputs or outputs controlled via a serial bus interface. It is suitable for designs needing low-power operation within the 1.65 V to 3.6 V range. Consider the QFN-EP-24 package constraints for PCB layout. Verify that the 400 kHz I2C speed meets the system's timing requirements and that the 160 mA total output current is sufficient for the connected loads.

Part Context

This part belongs to the XRA1201 family of I/O expanders from MaxLinear. It shares functional similarities with other devices in the series but differs in package type and specific suffix designations. The XR20M1170 and XRA1203 are related interface components from the same manufacturer, serving UART and GPIO expansion roles respectively.

Replacement Considerations

Publicly confirmed substitute part numbers for the XRA1201PIG24TR-F are not available in the provided reference data. Consult MaxLinear's official obsolescence notices or PCN documents for recommended alternatives if this part is no longer in production.
