XR16C850IJTR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16C850IJTR-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 optimize data loading and unloading from the controlling CPU. The device supports data rates up to 2.25 Mb/s and operates within a supply voltage range of 2.97 V to 5.5 V, compatible with 3.3 V and 5 V logic levels. It is housed in a TQFP-48 surface-mount package and functions within an industrial temperature range of -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Integrates 128-byte TX and RX FIFOs with counters for efficient CPU data management
• Supports Intel bus and PC COM port compatibility
• Operates on dual voltage supplies of 3.3 V and 5 V

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Intel bus interface systems
• PC COM port implementations
• Industrial communication modules requiring high-capacity buffering

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status via official datasheets before integration. Check for End-of-Life (EOL) notifications or Product Change Notices (PCN) that may affect long-term availability or manufacturing specifications.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this model when a single UART channel with large FIFO depth is required for CPU-intensive applications. Ensure the design accommodates the TQFP-48 footprint and thermal requirements for the specified operating temperature range. Verify voltage level compatibility between the host processor and the 3.3 V/5 V operational modes.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This component belongs to the XR16C850 series of VLIO UARTs. It shares functional similarities with other MaxLinear UARTs but is distinct in its single-channel configuration and specific FIFO counter architecture designed for Intel bus and PC COM port standards.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct substitutes include the XR16C850CM-F and XR16C850CV-F. These variants offer identical electrical characteristics but differ in packaging type, such as TQFP-48 tray options, which may impact board layout and assembly processes.
