ST16C580CQ48-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C580CQ48-F is a single-channel 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 intervention. The device supports high-speed serial communication with a maximum data rate of 1.5 Mbps. It operates within a supply voltage range of 2.97V to 5.5V, ensuring compatibility with both 3.3V and 5V logic systems. The component is housed in a 48-pin Thin Quad Flat Package (TQFP) designed for surface-mount assembly, measuring 9.2mm in length and 1.2mm in height. It 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 FIFO buffers to minimize processor overhead during serial data transfers.
• Supports auto-flow control mechanisms to manage data transmission efficiency and prevent buffer overflows.
• Operates on a wide supply voltage range of 2.97V to 5.5V, compatible with standard 3.3V and 5V logic levels.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring reliable serial communication interfaces
• Embedded devices needing UART connectivity for configuration or debugging
• Telecommunications equipment utilizing RS-232 or RS-485 protocols

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'F' against the manufacturer's current datasheet to confirm package dimensions and pinout compatibility. Ensure that the operating environment remains within the specified -40°C to +85°C range to maintain performance integrity. Confirm that the system power supply stays strictly between 2.97V and 5.5V to avoid electrical overstress. Check for any recent product change notices regarding lead times or material composition updates.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single UART channel with moderate speed requirements up to 1.5 Mbps is sufficient. The 16-byte FIFO offers a balance between cost and performance for applications not demanding high-throughput buffering. Consider the 48-pin TQFP package only if the PCB layout accommodates the required footprint and thermal dissipation characteristics. Evaluate alternative models if higher channel counts or faster data rates are necessary for the target application.
