XR16M554IV80TR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16M554IV80TR-F is a quad universal asynchronous receiver/transmitter (UART) integrated circuit manufactured by MaxLinear. It features four independent channels with 64-byte transmit and receive FIFOs, supporting data rates up to 16 Mb/s. The device operates on a single supply voltage ranging from 1.62 V to 3.63 V and is housed in an 80-LQFP package measuring 12x12 mm. Key functional blocks include internal oscillators, timer/counters, auto flow control, IrDA encoder/decoder, false start bit detection, and modem control capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Quad UART architecture with 64-byte FIFOs per channel for enhanced throughput management
• Integrated IrDA encoder and decoder supporting infrared communication protocols
• Hardware auto flow control and false start bit detection for signal integrity

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• High-speed serial communication interfaces requiring multiple independent ports
• Infrared data association (IrDA) compliant devices and peripherals
• Industrial control systems utilizing RS-232 signaling standards

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix TR-F indicates tape and reel packaging configuration. Check for current product lifecycle status as this series may be subject to discontinuation notices. Ensure compatibility with required voltage levels and operating temperature ranges before procurement.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when four independent UART channels are required within a single footprint. The 64-byte FIFO depth suits applications needing moderate buffering without external memory. Verify that the 1.62 V to 3.63 V supply range aligns with system power rails. Consider the 80-LQFP package dimensions for PCB layout constraints compared to smaller alternatives.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16M554 family of quad UARTs. It shares architectural similarities with other members like the XR16M554DIV64TR-F but differs in package type and pin count. The IV80 designation specifically refers to the 80-pin LQFP form factor, distinguishing it from 64-pin variants while maintaining identical electrical performance characteristics.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct substitutes include other XR16M554 variants such as XR16M554DIV64TR-F if pin compatibility allows. Cross-reference with XR16M654IV80-F for similar quad UART functionality. Verify pin-to-pin compatibility and register mapping before replacing existing designs.
