ST16C450CQ48-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C450CQ48-F is a single-channel Universal Asynchronous Receiver/Transmitter (UART) manufactured by MaxLinear. It operates within a supply voltage range of 2.97V to 5.5V and supports data rates up to 4 Mbps. The device features a 16-byte transmit FIFO and a 16-byte receive FIFO to enhance throughput efficiency. It is housed in a 48-pin TQFP surface-mount package with dimensions of 9.2mm length and 1.2mm height. The component functions reliably across an industrial temperature range from -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Integrates 16-byte transmit and receive FIFOs for improved data handling
• Supports high-speed asynchronous communication up to 4 Mbps
• Compatible with standard UART protocols including RS-232 and RS-485

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation control systems
• Embedded computing platforms requiring serial connectivity
• Telecommunications equipment interfaces

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific manufacturer source, as MaxLinear acquired Exar/Sipex product lines. Confirm that the part number suffix corresponds to the correct tape-and-reel or tray packaging variant intended for your assembly process. Ensure compatibility with existing design-in documentation before finalizing procurement orders.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single UART channel with moderate FIFO depth is required. It serves as a direct replacement for legacy Exar ST16C450 devices. Consider alternative models if multiple channels or higher data rates are necessary. Verify pinout compatibility during PCB layout updates to ensure seamless integration into existing designs.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This component belongs to the ST16C45x family of UART interface controllers. It shares functional similarities with other single-channel variants like the ST16C450CJ44TR but utilizes a different package configuration. The series is widely used in applications requiring reliable serial data transmission with reduced CPU overhead due to hardware flow control support.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The ST16C450CJ44TR is a documented equivalent offering identical functionality in a PLCC-44 package. Designers must account for physical footprint differences when substituting components. Electrical characteristics remain consistent between these variants.
