XR16L788CQ-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16L788CQ-F is an octal Universal Asynchronous Receiver/Transmitter (UART) interface integrated circuit manufactured by MaxLinear. It features eight independent UART channels, each equipped with a 64-byte transmit and receive FIFO buffer to enhance data throughput and reduce CPU overhead. The device supports data rates up to 6.25 Mb/s and operates within a supply voltage range of 2.97 V to 5.5 V. It is designed for industrial applications with a specified operating temperature range from 0°C to +70°C. The component is housed in a 100-lead QFP package and supports both Intel and Motorola bus interfaces.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer. Current availability is restricted, and standard procurement channels may not stock new units. Engineers should verify the authenticity of any remaining inventory through authorized distributors and review official discontinuation notifications for timeline details before initiating orders.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Designers requiring this specific octal configuration must account for its EOL status when planning long-term production. Alternative selection should focus on newer MaxLinear VLIO UART families that offer comparable channel counts and FIFO depths. Verify that the replacement part supports the required 64-byte FIFO size and compatible bus protocols to ensure seamless integration into existing system architectures.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The XR16L788CQ-F belongs to the XR16L788 series of VLIO UARTs, which are optimized for high-performance serial communication in embedded environments. This series integrates level shifters and supports various baud rates, making it suitable for legacy and modern industrial interfaces. The 'CQ' suffix indicates the commercial temperature grade and QFP packaging variant.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Official substitutes include other parts within the MaxLinear VLIO UART portfolio that maintain octal channel configurations. Verify compatibility regarding FIFO depth, voltage levels, and package dimensions to ensure mechanical and electrical fit during board redesigns.
