XR16L788IQ-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16L788IQ-F is a quad-channel Universal Asynchronous Receiver/Transmitter (UART) interface integrated circuit manufactured by MaxLinear. It features four independent UART channels with 128-byte transmit and receive FIFOs for each channel, supporting data rates up to 2 Mb/s. The device operates on a single power supply ranging from 2.97 V to 5.5 V, with typical operation at 3.3 V or 5 V. It is housed in a 100-lead PQFP package and supports industrial temperature ranges from -40°C to +85°C. The component includes support for IrDA, RS-232, and RS-485 protocols.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Integrates four independent UART channels with substantial 128-byte FIFO buffers per channel to minimize CPU intervention.
• Supports multiple communication standards including IrDA, RS-232, and RS-485 within a single package.
• Features low-power operation modes designed to reduce current consumption during idle periods.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring multi-port serial connectivity.
• Telecommunications equipment utilizing RS-232 or RS-485 interfaces.
• Embedded control units needing high-throughput serial data handling with IrDA support.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify component authenticity through authorized distributors or certified secondary market suppliers due to potential availability constraints. Confirm the specific manufacturing date code and lot traceability to ensure compliance with RoHS directives and humidity sensitivity levels. Request detailed datasheets and test reports to validate electrical parameters against original specifications before integration into production designs.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a design requires four distinct serial ports with deep buffering capabilities in a compact form factor. Ensure the system voltage aligns with the 2.97 V to 5.5 V operating range. Consider the 100-lead PQFP package size and thermal requirements during PCB layout. Verify that the target application does not require higher data rates than 2 Mb/s or additional protocol support beyond IrDA, RS-232, and RS-485.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16C864 series of quad-channel UARTs from MaxLinear. It shares architectural similarities with other members of the family but is distinguished by its specific pinout, packaging, and FIFO depth configuration. The series is designed for applications demanding high-density serial communication interfaces in embedded environments.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct replacements may include other quad-channel UARTs from MaxLinear or compatible devices from other manufacturers offering similar FIFO depths and pinouts. Verify electrical compatibility, especially regarding voltage levels and signal integrity. Check for pin-to-pin compatibility if board space is constrained. Consult official substitution guides for any functional differences in register maps or control signals.
