XR16V654IV-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16V654IV-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 data 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, supporting both Intel and Motorola bus protocols. The component is housed in a 48-lead QFN package and is rated for industrial temperature operation from -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix IV against official MaxLinear documentation to confirm the industrial temperature grade (-40°C to +85°C) and package type (QFN-48). Ensure compatibility with the target system's voltage levels and bus protocol requirements before integration. Cross-reference the part number with current manufacturer lifecycle status to avoid obsolescence risks during production planning.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when multiple UART ports are required in a compact form factor. The 64-byte FIFOs are suitable for applications with bursty data traffic. Verify that the host processor can interface with the supported Intel or Motorola bus modes. Consider power consumption specifications if battery-operated, noting the operating current varies with speed and voltage.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16V654 series of quad UARTs from MaxLinear. It shares functional similarities with other members like the XR16V654IL-F but differs in package and temperature rating. The series is designed for embedded applications needing robust serial I/O capabilities without external FIFO buffers.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Check for direct pin-to-pin replacements within the same family, such as the XR16V654IL-F, ensuring temperature and package differences are acceptable. Verify electrical parameters match exactly to ensure seamless integration without schematic changes.
