XR16C854CJ-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16C854CJ-F is a quad-channel Universal Asynchronous Receiver/Transmitter (UART) interface integrated circuit manufactured by MaxLinear. It features 128-byte transmit and receive FIFOs for each channel, supporting data rates up to 2 Mb/s. The device operates within a supply voltage range of 2.97 V to 5.5 V and draws between 3 mA and 6 mA. It is housed in a PLCC-68 package suitable for surface mount installation. The component supports both Intel and Motorola bus interfaces and functions across an industrial temperature range from -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Quad-channel architecture with independent 128-byte FIFOs per channel
• Support for Intel and Motorola bus compatibility modes
• Integrated internal oscillator and timer/counter functionality

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial communication systems requiring multi-port serial connectivity
• Embedded controllers needing high-speed UART interfaces
• Data acquisition systems utilizing buffered serial transmission

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'CJ' against official MaxLinear documentation to confirm pinout and electrical specifications, as distributor listings may vary. Confirm RoHS compliance status directly with the manufacturer or authorized agents. Check for End-of-Life (EOL) notices or Not Recommended for New Designs (NRND) status before finalizing procurement plans.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when four independent UART channels with deep buffering are required in a single package. Ensure the design accommodates the PLCC-68 footprint and meets the 2.97V to 5.5V power supply requirements. Verify that the operating temperature range of -40°C to +85°C aligns with the target application environment.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16C854 series of enhanced UARTs from MaxLinear. It shares core functional similarities with other variants like the XR16C854IJ-F but differs in package type and potentially thermal characteristics. The series is designed for applications demanding reliable serial communication with reduced CPU overhead through hardware flow control and FIFO management.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct substitutes include other members of the XR16C854 family such as the XR16C854IJ-F or XR16C854DIV-F, provided the package difference (PLCC vs LQFP) is acceptable. Cross-reference with the XR16C864CQ-F if a QFP package is preferred, noting the change in pin count.
