ST16C550CJ44TR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C550CJ44TR-F is a single Universal Asynchronous Receiver/Transmitter (UART) integrated circuit manufactured by MaxLinear. It features a 16-byte transmit and receive FIFO buffer to enhance data throughput and reduce CPU overhead. The device operates within a supply voltage range of 2.97 V to 5.5 V, supporting both 3.3 V and 5 V logic systems. It is housed in a PLCC-44 surface-mount package and supports data rates up to 4 Mb/s. The component is designed for industrial applications with an operating temperature range from 0°C to +70°C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Integrated 16-byte transmit and receive FIFO buffers for efficient data handling
• Compatible with Intel and Motorola bus protocols for flexible system integration
• Supports dual voltage operation at 3.3 V and 5 V levels

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial communication systems requiring reliable serial data transfer
• Embedded controllers utilizing Intel or Motorola bus architectures
• Multi-drop serial networks needing FIFO-based buffering

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing this part number. Confirm the manufacturer designation as MaxLinear, noting previous branding under Exar Corporation. Ensure compatibility with the PLCC-44 footprint during procurement planning.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component for designs requiring a single UART channel with moderate FIFO depth. It serves as a direct replacement for legacy Exar ST16C550 devices. Verify that the PLCC-44 package size fits the target PCB layout constraints before finalizing the design.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the ST16C550 series of UART interface ICs. It provides a single channel solution, distinguishing it from dual-channel variants like the ST16C2550 or quad-channel models such as the ST16C554. The series is characterized by its 16-byte FIFO architecture and broad voltage compatibility.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The ST16C550CJ44 is functionally equivalent to the XR16C550CJ44. Designers may also consider the ST16C550CJ44-F as a standard tube-packaged alternative if reel quantities are not required.
