XR16V2551IL-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16V2551IL-F is a dual universal asynchronous receiver/transmitter (UART) integrated circuit manufactured by MaxLinear. It features two independent UART channels, each equipped with a 16-byte transmit and receive FIFO buffer to enhance data throughput and reduce CPU intervention. The device supports high-speed serial communication with data rates up to 16 Mb/s. It operates within a supply voltage range of 2.25 V to 3.6 V and is designed for industrial temperature ranges from -40°C to +85°C. The component is housed in a 48-lead Thin Quad Flat Package (TQFP) with a 7x7 mm footprint.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Dual-channel architecture providing independent serial communication paths
• Integrated 16-byte FIFO buffers per channel to minimize processor overhead
• Support for multiple baud rate generators and standard protocol formats
• Low power consumption suitable for battery-operated systems

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation control systems requiring reliable serial I/O
• Telecommunications equipment utilizing RS-232 or RS-422 interfaces
• Embedded computing platforms needing additional UART ports
• Medical instrumentation with serial data acquisition requirements

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix and manufacturer revision level against current MaxLinear documentation to ensure compatibility with design specifications. Confirm availability status as components may be subject to discontinuation notices. Validate package markings and lot traceability requirements prior to procurement to meet quality standards.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual independent UARTs with moderate FIFO depth are required. Compare against the XR16V2651 if 32-byte FIFOs are needed, or the XR16V2552 if quad channels are necessary. Ensure the 48-TQFP package fits the PCB layout constraints and thermal management plan. Verify voltage levels match the target system logic families.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16V255x family of dual UART controllers. It shares architectural similarities with the XR16V2552 but offers fewer channels. It serves as a bridge between parallel bus systems and serial communication protocols, commonly replacing legacy 16C550 or 16C650 equivalents with enhanced performance and lower power characteristics.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Check for direct pin-compatible alternatives such as the XR16V2552IMTR-F if higher channel count is acceptable. Verify functional equivalence with other dual UART ICs from different manufacturers regarding register compatibility and electrical specifications before substitution.
