XR16C854CJTR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16C854CJTR-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 on a single power supply ranging from 2.97 V to 5.5 V, with typical current consumption of 3 mA at 3.3 V and 6 mA at 5 V. It is housed in a PLCC-68 surface-mount package and supports both Intel and Motorola bus protocols.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Quad channel architecture with dedicated 128-byte FIFOs for each transmitter and receiver to enhance CPU efficiency.
• Dual bus compatibility supporting both Intel and Motorola interface protocols for flexible system integration.
• Integrated modem control signals and automatic flow control capabilities for reliable serial communication.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring multiple serial ports
• Telecommunications equipment with high-throughput serial interfaces
• Embedded computing platforms needing robust UART connectivity

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'CJTR' against official MaxLinear documentation to confirm tape-and-reel packaging and temperature grade. Confirm end-of-life status as distributor listings may vary. Ensure RoHS compliance matches project requirements before procurement.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when four independent UART channels are required in a compact PLCC-68 footprint. Compare against the XR16C854DIV-F if an LQFP-64 package is preferred. Verify that the 2 Mb/s maximum baud rate meets application needs compared to higher-speed alternatives like the XR16V654 series.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the MaxLinear VLIO UART family, designed for high-performance serial communication. It serves as a multi-channel solution replacing discrete UART components or lower-density interface ICs in complex embedded designs.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The XR16C854IJ-F is a pin-compatible alternative in a PLCC-68 package. For lead-free or different temperature variants, check the XR16C854DIV-F in LQFP-64. Verify electrical specifications match before substitution.
