XR16C854IJ-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16C854IJ-F is a quad universal asynchronous receiver and transmitter manufactured by MaxLinear. It features four independent UART channels with 128-byte transmit and receive FIFOs, supporting data rates up to 2 Mb/s. The device operates within a supply voltage range of 2.97 V to 5.5 V, consuming 6 mA of operating current. It supports dual bus interfaces compatible with Intel and Motorola protocols. The component is housed in a PLCC-68 package for surface mount installation and functions reliably across an industrial temperature range from -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Quad channel architecture with 128-byte TX and RX FIFOs for enhanced throughput
• Dual footprint interface supporting both Intel and Motorola bus protocols
• Integrated modem control signals and automatic flow control capabilities

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial communication systems requiring multi-port serial connectivity

• Data acquisition equipment needing high-capacity FIFO buffering

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix and package type against the original design specifications before procurement. Confirm that the PLCC-68 footprint matches the PCB layout requirements. Check for any recent product discontinuation notices or lifecycle changes from MaxLinear to ensure long-term availability for production runs.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when four independent UART ports are required with substantial FIFO depth to handle burst data traffic. Ensure the system power supply accommodates the 2.97 V to 5.5 V input range. Verify compatibility with the target microcontroller's bus protocol, as the device supports specific Intel and Motorola interface modes.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16C854 series of enhanced quad UARTs. It shares functional similarities with other members like the XR16C854DIV-F but differs in package style, using PLCC-68 instead of LQFP-64. The series is designed for applications demanding reliable serial communication with reduced CPU overhead due to large FIFO buffers.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The XR16C854DIV-F offers identical electrical performance and functionality but utilizes an LQFP-64 package. Direct substitution requires verifying PCB footprint compatibility. Other series members may differ in pinout or package dimensions.
