XRA1201PIL24-F

Overview

The XRA1201PIL24-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 an interrupt output capability and provides a total output current of 160 mA with a power dissipation rating of 200 mW. It is housed in a QFN-EP-24 package designed for surface mount installation. The component 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 serial interfaces.
• Includes dedicated interrupt output functionality to signal state changes to the host processor.
• Supports low-voltage operation suitable for modern embedded systems requiring efficient power management.

Applications

• Embedded systems requiring additional digital I/O ports via serial communication.
• Consumer electronics utilizing I2C/SMBus peripheral expansion.
• Industrial control modules needing reliable GPIO interfacing in harsh environments.

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm RoHS compliance status prior to integration. Check for moisture sensitivity handling requirements during storage and assembly processes. Ensure packaging integrity matches design specifications for surface mount technology applications.

Selection Notes

Select this model when 16-bit expansion is required over other variants like the XRA1200 series which offers fewer bits. Consider the QFN-EP-24 package size against board space limitations. Verify that the 400 kHz maximum clock speed meets system timing requirements compared to slower 100 kHz alternatives.

Part Context

This component belongs to the XRA1201 series of I/O expanders. It shares functional similarities with the XRA1203 but differs in maximum clock frequency specifications. The part is distinct from UART interface ICs such as the XR20M series, serving specifically as a parallel-to-serial converter for GPIO signals rather than serial communication bridging.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official MaxLinear resources for qualified replacements or evaluate pin-compatible alternatives within the same product family if sourcing becomes restricted.
