XR28V382IL32-F

Overview

The XR28V382IL32-F is a dual Low Pin Count (LPC) Universal Asynchronous Receiver/Transmitter manufactured by MaxLinear. It operates on a single 3.3 V power supply with a voltage range of 2.97 V to 3.63 V. The device features two independent UART channels, each equipped with a 128-byte FIFO buffer for data storage. It supports data transmission rates up to 3 Mb/s and draws a typical operating current of 12 mA. Designed for surface-mount installation, it is housed in a QFN-32 package. The component functions within an industrial temperature range from -40°C to +85°C.

Feature Summary

• Dual-channel architecture providing independent LPC UART interfaces
• Integrated 128-byte FIFO per channel to manage data flow
• Supports high-speed asynchronous serial communication up to 3 Mb/s
• Operates on a standard 3.3 V single power supply

Applications

• Industrial control systems requiring robust serial connectivity
• Embedded devices utilizing LPC bus protocols
• Data acquisition modules needing buffered serial input/output
• Communication gateways interfacing multiple peripheral devices

Procurement Notes

This component is officially classified as End-of-Life (EOL) by the manufacturer. Distribution availability is restricted, and Mouser indicates that the product is currently not sold in certain regions. Verification of final supplier stock and alternative sourcing channels is required before procurement planning.

Selection Notes

Designers should consider the EOL status when selecting this part for new products. The QFN-32 package requires specific PCB footprint considerations. Ensure the application environment stays within the specified -40°C to +85°C operating temperature range and strictly adheres to the 3.3 V power supply constraints.

Part Context

The XR28V382IL32-F belongs to the XR28V382 series of LPC UARTs. It is distinct from the XR28V382IL32-0A-EB, which is an evaluation board used for testing this specific IC. The device serves as a core interface controller for converting parallel internal data to serial streams in low-pin-count applications.

Replacement Considerations

As the part is discontinued, verify if the XR28V382IL32 variant without the suffix or other MaxLinear LPC UARTs are suitable replacements. Cross-reference pinouts and electrical specifications carefully to ensure compatibility.
