XR16L784IV-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16L784IV-F is a quad universal asynchronous receiver transmitter (QUART) 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 intervention. The device supports data rates up to 6.25 Mbps and operates within an industrial temperature range of -40°C to +85°C. It accepts supply voltages ranging from 2.25 V to 3.6 V and is housed in a 64-pin LQFP package measuring 10x10 mm.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Integrates four independent UART channels with dedicated 64-byte transmit and receive FIFOs for efficient data buffering.
• Supports standard Intel and Motorola bus interfaces for flexible system integration.
• Operates reliably across the full industrial temperature range of -40°C to +85°C.
