Universal Asynchronous Receiver Transmitters

TL16C554IFN Description

The TL16C554IFN from Texas Instruments is a high-performance quad UART (Universal Asynchronous Receiver Transmitter) designed for embedded communication systems requiring robust serial data handling. Housed in a 68-PLCC package, this IC integrates four independent UART channels, each equipped with a 16-byte FIFO to enhance data throughput and reduce CPU overhead. Operating within a 4.75V to 5.25V supply range, it supports data rates up to 1Mbps, making it suitable for high-speed serial communication. The device is RoHS3 compliant and adheres to REACH and EAR99 regulations, ensuring environmental and export compliance.

TL16C554IFN Features

• Quad UART Channels: Four independent UARTs enable simultaneous multi-port communication, ideal for systems requiring parallel serial interfaces.
• 16-Byte FIFOs: Each channel includes a FIFO buffer to minimize CPU interrupts and improve data flow efficiency.
• Modem Control: Integrated modem control signals (RTS, CTS, DSR, DTR, etc.) simplify interfacing with peripheral devices.
• False Start Bit Detection: Enhances data integrity by identifying and handling erroneous start bits in noisy environments.
• High-Speed Operation: Supports 1Mbps data rates, suitable for demanding industrial and embedded applications.
• Surface-Mount Design: 68-PLCC package ensures compact PCB integration, with MSL 3 (168 hours) moisture sensitivity for reliable assembly.
