XR16V654IVTR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16V654IVTR-F is a quad universal asynchronous receiver/transmitter (UART) interface integrated circuit manufactured by MaxLinear. It features four independent UART channels, each equipped with 64-byte transmit and receive FIFOs to enhance system throughput and reduce CPU overhead. The device supports data rates up to 16 Mbps and operates within a supply voltage range of 2.25 V to 3.6 V. It integrates an internal oscillator and timer/counter capabilities. The component is housed in a 64-pin LQFP package measuring 10 mm x 10 mm with a height of 1.40 mm. It supports Intel and Motorola bus interfaces and includes automatic flow control and modem control signals.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'IVTR-F' against official MaxLinear documentation to confirm temperature grade and tape-and-reel packaging specifications. Cross-reference the manufacturer's discontinuation notices, as related variants in this series have been subject to end-of-life notifications. Ensure compatibility with existing PCB footprints for the 64-LQFP package before procurement.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a design requires four independent UART channels with substantial FIFO depth to minimize processor interrupts. Verify that the operating environment falls within the specified voltage range of 2.25 V to 3.6 V. Consider the 64-LQFP package dimensions if space constraints are critical. Compare against lower-capacity variants like the XR16V554 if fewer channels or smaller FIFOs suffice.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16V654D family of low-voltage UART controllers. It shares architectural similarities with other members like the XR16V654IL-F but differs in package type and potentially temperature rating. The 'DIVTR' designation typically indicates a specific tape-and-reel configuration for automated assembly, distinct from tray-packaged equivalents.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct substitutes include the XR16V654DIVTR-F, which shares identical electrical characteristics and pinout. Evaluate the XR16V654IL-F if a QFN package is acceptable for the design. Verify functional equivalence regarding FIFO size and supported baud rates before swapping components.
