XR16C854IQTR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16C854IQTR-F is a quad universal asynchronous receiver and transmitter manufactured by MaxLinear. It operates within a supply voltage range of 2.97 V to 5.5 V, with a maximum data rate of 2 Mb/s per channel. The device features 128-byte transmit and receive FIFOs for each UART channel. It is housed in a PLCC-68 package designed for surface mount technology. The component supports an operating temperature range from -40°C to +85°C and includes internal oscillator and timer/counter capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Quad UART architecture with dual footprint interface compatibility
• 128-byte TX and RX FIFOs per channel for enhanced throughput
• Support for Intel and Motorola bus protocols

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial communication systems requiring multiple serial ports
• Embedded control units utilizing RS-232 or RS-485 interfaces
• Data acquisition modules needing high-capacity buffering

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'IQTR' against official MaxLinear documentation to confirm the tape-and-reel packaging and industrial temperature grade. Confirm current lifecycle status as distributors may list this part as obsolete or not recommended for new designs. Ensure ESD handling procedures are followed during assembly due to moisture sensitivity classification.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this model when four independent UART channels are required in a single package. Compare against the XR16C854DIV-F if a LQFP-64 package is preferred instead of PLCC-68. Verify that the 2 Mb/s data rate meets system requirements, noting that higher-speed alternatives like the XR16V654 series offer faster rates but different power characteristics.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This component belongs to the XR16C854 series of enhanced UARTs from MaxLinear. The series is characterized by large FIFO buffers and flexible bus interface options. The 'I' indicates industrial temperature range, while 'QTR' specifies the reel packaging format. This family serves as a drop-in replacement for legacy 16C854 devices in many applications.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Designers should consult MaxLinear's official obsolescence notices or technical support for validated cross-reference recommendations before finalizing the design.
