ST16C550CQ48-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C550CQ48-F is a single-channel Universal Asynchronous Receiver/Transmitter (UART) interface integrated circuit manufactured by MaxLinear. It operates within a supply voltage range of 2.97 V to 5.5 V and supports data rates up to 1.5 Mb/s. The device features a 16-byte transmit and receive FIFO buffer to enhance throughput efficiency. It is housed in a 48-lead TQFP package with dimensions of 7x7 mm and is rated for an operating temperature range of -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Integrates a 16-byte transmit and receive FIFO buffer to minimize CPU intervention during serial data transfers.
• Supports both Intel and Motorola bus interfaces for flexible system integration.
• Operates on a wide supply voltage range from 2.97 V to 5.5 V, compatible with 3.3 V and 5 V logic systems.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial control systems requiring reliable asynchronous serial communication.
• Embedded computing platforms utilizing standard UART protocols.
• Telecommunications equipment interfacing with peripheral devices.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'F' against the manufacturer's current datasheet to confirm packaging and material compliance details. Check for End-of-Life (EOL) status or Production Change Notices (PCN) as availability may be limited. Ensure the 48-TQFP footprint matches the target PCB design constraints before finalizing procurement.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single UART channel with moderate FIFO depth is required. Compare against the quad-channel ST16C554 series if multiple independent serial ports are needed. Verify that the 1.5 Mb/s maximum data rate meets the application's baud rate requirements and that the TQFP-48 package is suitable for the assembly process.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the ST16C55xD family of UART controllers. It shares functional similarities with other single-channel variants like the ST16C1550 but offers higher data rate capabilities. The device is designed to replace legacy UART components in modern embedded designs requiring robust serial I/O management.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Potential substitutes include the ST16C1550CQ48-F for lower-speed applications or the ST16C554DIJ68-F for multi-channel requirements. Verify pin compatibility and FIFO sizes when cross-referencing with other MaxLinear or Exar UART controllers.
