Universal Asynchronous Receiver Transmitters

TL16C550CIFN Description

The TL16C550CIFN from Texas Instruments is a high-performance Universal Asynchronous Receiver Transmitter (UART) designed for reliable serial communication in embedded systems. This obsolete but robust IC integrates a single-channel UART with advanced features, supporting data rates up to 1Mbps and operating within a 3V to 5.25V supply range. Packaged in a 44-PLCC form factor, it is optimized for surface-mount applications and complies with ROHS3 and REACH environmental standards. Its 16-byte FIFO buffers enhance data throughput, while integrated modem control, auto flow control, and false start bit detection ensure signal integrity in noisy environments.

TL16C550CIFN Features

• 16-byte FIFOs: Reduces CPU overhead by buffering transmit/receive data.
• Auto Flow Control: Hardware-based (CTS/RTS) for seamless data synchronization.
• Modem Control: Supports DSR, DTR, RI, and CD signals for modem interfacing.
• False Start Bit Detection: Improves noise immunity in asynchronous communication.
• Wide Voltage Range (3V–5.25V): Compatible with 3.3V and 5V systems.
• 1Mbps Max Data Rate: Suitable for high-speed serial links.
• Surface-Mount (44-PLCC): Compact footprint for space-constrained designs.
• Industrial Compliance: EAR99, RoHS3, and REACH Unaffected certified.

TL16C550CIFN Applications

• Industrial Automation: Reliable UART for PLCs, sensors, and control systems.
• Telecom Equipment: Modem and legacy serial port interfaces.
• Embedded Systems: Microcontroller-based designs requiring buffered serial I/O.
• Point-of-Sale (POS) Terminals: Robust communication in retail hardware.
• Medical Devices: Secure data transmission in diagnostic equipment.

Conclusion of TL16C550CIFN

The TL16C550CIFN stands out for its FIFO-enhanced performance, auto flow control, and noise-resistant design, making it ideal for legacy or noise-prone serial communication systems. While marked obsolete, its wide voltage range and modem support ensure compatibility with diverse applications.
