XR16C850CJ-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16C850CJ-F is a single-channel Universal Asynchronous Receiver/Transmitter (UART) interface integrated circuit manufactured by MaxLinear. It features 128-byte transmit and receive FIFOs with counters to facilitate efficient data loading and unloading from the controlling CPU. The device supports operation at data rates up to 2.25 Mb/s and accepts supply voltages of 3.3 V or 5 V, operating within a voltage range of 2.97 V to 5.5 V. It is housed in a 48-pin Thin Quad Flat Package (TQFP-48) and functions as a drop-in replacement for standard PC COM ports and Intel bus architectures.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Integrates 128-byte transmit and receive FIFOs equipped with counters to optimize CPU data transfer efficiency.
• Supports dual voltage operation at 3.3 V and 5 V levels for flexible system integration.
• Compatible with Intel bus and PC COM port standards for direct architectural substitution.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• PC COM port implementations
• Intel bus architecture interfaces
• General-purpose serial communication systems

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify component authenticity through official MaxLinear channels or authorized distributors. Confirm RoHS compliance status and check current lifecycle status, as availability may vary. Ensure the TQFP-48 package matches your PCB footprint requirements before procurement.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single UART channel with deep buffering is required. It is suitable for designs needing compatibility with legacy Intel bus protocols or standard PC serial ports. Verify that the 2.25 Mb/s maximum data rate meets your application's throughput needs.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16C850 series of enhanced UARTs. It shares functional similarities with other members like the XR16C850CM-F but differs in package type. The series is designed to provide high-performance serial I/O capabilities with reduced CPU overhead via large FIFO buffers.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The XR16C850CM-F is a related variant within the same product family. Verify pinout compatibility and package dimensions (TQFP-48 vs. alternative packages) before substituting. Ensure electrical specifications align with the target design requirements.
