ST16C450CQ48

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C450CQ48 is a single Universal Asynchronous Receiver/Transmitter (UART) integrated circuit manufactured by Sipex. It operates within a supply voltage range of 3.0V to 5.5V and supports data transmission rates up to 2.5 Mbps. The device features a 16-byte transmit and receive FIFO buffer, which enhances system performance by reducing CPU intervention during high-speed serial communication. It is housed in a 48-lead Thin Quad Flat Package (TQFP) with dimensions of 7mm x 7mm. The component includes comprehensive control signals for flow management and interrupt generation, ensuring reliable asynchronous data transfer in embedded applications.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Integrated 16-byte FIFO buffers for both transmission and reception to minimize processor overhead
• Supports standard asynchronous serial protocols with programmable baud rate generators
• Includes hardware flow control signals such as RTS, CTS, DTR, and DSR for robust data management
• Provides interrupt capabilities based on receive data availability, transmit holding register empty, and status changes

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring reliable serial communication interfaces
• Embedded controllers needing high-speed UART connectivity with reduced CPU load
• Telecommunications equipment utilizing asynchronous data transfer standards
• Point-of-sale terminals and barcode scanners requiring robust serial I/O

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the manufacturer designation, as Sipex assets were acquired by MaxLinear. Confirm the package type is TQFP-48 and check for RoHS compliance status. Ensure the operating temperature range matches your specific application requirements before finalizing procurement decisions.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single UART channel with moderate FIFO depth is required. It is suitable for applications where 3.3V or 5V logic levels are used. Consider alternative parts if higher pin counts or multiple UART channels are needed simultaneously.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the ST16C45x series of UART controllers. It shares functional similarities with other members like the ST16C450 but differs in package options and specific electrical characteristics. The series is designed for general-purpose asynchronous communication tasks in industrial and commercial environments.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Check for direct equivalents from MaxLinear, which now holds the Sipex portfolio. Verify pin compatibility and electrical specifications against similar UART ICs from other manufacturers if sourcing from alternative suppliers.
