XR28V382IL32TR-F

Overview

The XR28V382IL32TR-F is a dual Low Pin Count (LPC) Universal Asynchronous Receiver/Transmitter manufactured by MaxLinear. It integrates two independent UART channels, each equipped with a 128-byte FIFO buffer to enhance data throughput and reduce CPU overhead. The device operates on a single 3.3 V power supply within a voltage range of 2.97 V to 3.63 V. It supports data rates up to 3 Mb/s and functions reliably across an industrial temperature range from -40°C to +85°C. The component draws 12 mA during operation and is housed in a QFN-32 surface-mount package.

Feature Summary

• Dual-channel architecture providing independent LPC UART interfaces
• Integrated 128-byte FIFO per channel for efficient data buffering
• Supports high-speed asynchronous communication up to 3 Mb/s
• Designed for low-power operation with standard 3.3 V logic levels

Applications

• Industrial control systems requiring multiple serial connections
• Embedded devices needing LPC bus interface capabilities
• Automotive electronics utilizing robust UART communication
• IoT gateways managing sensor data streams

Procurement Notes

Verify the specific suffix TR-F against official MaxLinear documentation to confirm tape-and-reel packaging requirements. Confirm RoHS compliance status through current datasheets as regulatory standards may evolve. Check for End-of-Life notifications or Product Change Notices that could impact long-term availability. Ensure the supplier provides traceability documents matching the manufacturer's lot codes.

Selection Notes

Select this component when a design requires two isolated UART ports with substantial buffering capacity. The 128-byte FIFO is suitable for applications with bursty data traffic to prevent overflow. Verify that the system voltage aligns with the 3.3 V nominal requirement. Consider the QFN-32 thermal performance if operating at maximum data rates in enclosed environments.

Part Context

This part belongs to the XR28V382 series of LPC UARTs from MaxLinear. It complements other interface solutions like the XR34350 multiprotocol transceiver by focusing specifically on asynchronous serial communication. Unlike general-purpose UARTs, this device is optimized for LPC bus compatibility, making it distinct within the MaxLinear portfolio of interface integrated circuits.
