XR16V554IVTR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16V554IVTR-F is a quad universal asynchronous receiver/transmitter (UART) interface integrated circuit manufactured by MaxLinear. It operates within a supply voltage range of 2.25 V to 3.6 V and supports data rates up to 4 Mb/s. The device features sixteen-byte transmit and receive FIFOs for each channel, enhancing system performance by reducing CPU intervention. It is housed in a surface-mount LQFP-64 package and is rated for an operating temperature range from -40°C to +85°C. The typical operating current ranges between 1.7 mA and 3 mA.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Integrates four independent UART channels with dedicated 16-byte transmit and receive FIFOs to minimize processor overhead.
• Supports high-speed serial communication with data rates reaching 4 Mb/s across all channels.
• Compatible with Intel bus protocols for seamless integration into standard computing architectures.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial control systems requiring multiple serial communication ports
• Embedded computer motherboards and expansion cards
• Telecommunications equipment utilizing Intel bus interfaces

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'IVTR-F' against official MaxLinear documentation to confirm the exact tape-and-reel packaging configuration and industrial temperature grade. Ensure compatibility with the target board's 3.3 V logic levels and LQFP-64 footprint before finalizing procurement orders.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a design requires four distinct UART interfaces with moderate speed capabilities under low-voltage operation. It serves as a suitable alternative to legacy 5 V UARTs when transitioning to 3.3 V or lower power domains while maintaining FIFO-based data buffering.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16V554D series of VLIO UARTs from MaxLinear. It shares functional similarities with other quad UART devices like the XR16M554DIV64TR-F but is distinguished by its specific 2.25 V to 3.6 V operating range and 4 Mb/s data rate specification.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The XR16V554DIV-F is a tray-packaged variant of the same core device. Verify if the change from tape-and-reel to tray packaging affects the assembly process requirements.
