UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16M654IV80-F is a quad Universal Asynchronous Receiver and Transmitter (UART) integrated circuit manufactured by MaxLinear, Inc. It operates within a supply voltage range of 1.62V to 3.63V and supports data rates up to 16 Mbps at a 4X sampling rate. Each of the four independent channels includes 64 bytes of transmit and receive FIFOs with programmable trigger levels. The device features automatic hardware (RTS/CTS) and software (Xon/Xoff) flow control, IrDA 1.0 encoder/decoder support, and selectable Intel or Motorola bus interfaces. It is housed in an 80-pin LQFP package.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

Quad UART architecture with 64-byte transmit and receive FIFOs per channel
Support for both Intel and Motorola data bus interface modes
Automatic hardware and software flow control mechanisms
Integrated wireless infrared (IrDA 1.0) encoder and decoder

UARTs (Universal Asynchronous Receiver Transmitter) Applications

Telecommunication network routers
Ethernet network routers
Cellular data devices
Factory automation and process controls

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range. Confirm that the 'F' suffix aligns with the required tape and reel packaging format if applicable. Ensure compatibility with existing system power supplies operating between 1.62V and 3.63V before finalizing procurement specifications.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a low-voltage quad UART solution with high throughput is required. The 80-pin LQFP package is suitable for designs needing Intel bus compatibility without the additional pinout of the 100-pin variant. Consider the 64-byte FIFO depth for applications requiring reduced CPU interrupt servicing overhead compared to standard 16-byte FIFO devices.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16M654 series, which provides enhanced quad UART functionality compatible with industry standards like the ST16C554. The IV80 designation specifically identifies the 80-lead LQFP package variant designed for Intel bus mode operation. It serves as a modern replacement for legacy UARTs in portable and telecommunications equipment requiring multi-channel serial communication.
