XR16V554IV-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16V554IV-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 four independent channels, each equipped with 16-byte transmit and receive FIFOs to enhance system performance. It is housed in a 64-pin LQFP package and is designed for industrial temperature ranges from -40°C to +85°C. The component draws between 1.7 mA and 3 mA during operation.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Integrates four independent UART channels with dedicated 16-byte FIFO buffers for each transmitter and receiver path.
• Supports high-speed serial communication with data rates reaching 4 Mb/s under standard operating conditions.
• Compatible with Intel bus architecture for simplified integration into legacy or specific embedded systems.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation controllers requiring multiple serial communication ports.
• Embedded systems utilizing Intel-compatible bus interfaces.
• Telecommunications equipment needing reliable RS-232 or RS-485 connectivity.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the exact suffix IV against official MaxLinear documentation to confirm pinout and package dimensions. Ensure compatibility with the target board's thermal management requirements for the LQFP-64 form factor. Cross-reference RoHS compliance status directly with the manufacturer's current product change notices before finalizing procurement plans.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when four independent UART channels are required within a single IC footprint. The 16-byte FIFO depth helps mitigate buffer overflows in high-throughput applications. Verify that the system power supply remains stable within the 2.25 V to 3.6 V window to ensure correct logic level translation and timing accuracy across all channels.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16V554D series of quad UARTs. It shares functional similarities with other members like the XR16V554DIV-F but differs in packaging and temperature grade specifications. The IV suffix typically denotes a specific industrial-grade variant within the broader VLIO UART family offered by MaxLinear.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The XR16V554DIV-F is a related variant within the same series. Verify if the package type and temperature range differences allow for direct substitution without PCB redesign. Consult official cross-reference guides for any electrical parameter deviations.
