TI TL16C554AIPN Quad UART with 16-Byte FIFOs
The Texas Instruments TL16C554AIPN is a highly integrated quad universal asynchronous receiver/transmitter (UART) designed to streamline serial communication in embedded systems. This CMOS-based IC features four independent UART channels, each equipped with 16-byte transmit and receive FIFO buffers to minimize CPU overhead during high-speed data transfers. Housed in a 68-pin plastic quad flat package (PN), the device operates within a wide voltage range of 2.97V to 5.5V and supports industrial temperature ranges (-40°C to +85°C), ensuring reliability in harsh environments. Compliant with industry-standard communication protocols, it is tailored for applications requiring multiple serial ports with robust error detection and flexible baud rate generation.
Features
The TL16C554AIPN distinguishes itself with advanced functionality, including programmable baud rates up to 1.5 Mbps, automatic hardware/software flow control, and support for 5-bit to 8-bit data formats. Each UART channel incorporates modem control signals (RTS, CTS, DSR, DTR) and parity error detection, alongside break character generation and multi-drop addressing modes. The 16-byte FIFOs reduce interrupt frequency by 16x compared to single-byte systems, enhancing system efficiency. Additional features include a loopback diagnostic mode, prioritization of interrupt-driven I/O, and compatibility with RS-232, RS-485, and IrDA protocols, making it adaptable to diverse communication standards.
Applications
This UART is ideal for systems demanding multi-channel serial communication, such as industrial automation controllers, point-of-sale terminals, networking equipment, and legacy device interfacing. It is widely deployed in embedded computing platforms, including IoT gateways and telecommunication infrastructure, where reliable data transfer between microcontrollers, sensors, and peripherals is critical. The TL16C554AIPN also serves in medical devices, automotive diagnostics, and multi-port serial server applications, offering scalability for designs requiring simultaneous management of multiple serial data streams.
Selection Advantages
Choosing the TL16C554AIPN provides a cost-effective solution for reducing system complexity through its quad-channel integration, eliminating the need for multiple discrete UARTs. Its deep FIFOs and intelligent interrupt handling significantly optimize CPU utilization, while broad protocol compatibility ensures seamless integration into existing designs. The device's low-power CMOS technology and extended temperature tolerance cater to energy-sensitive and ruggedized applications. Furthermore, Texas Instruments' robust technical support and long-term product lifecycle commitment make it a dependable choice for both prototyping and high-volume production environments.
