UARTs (Universal Asynchronous Receiver Transmitters) are important components of the interface, allowing communications between two devices or systems. The TL16C554APN is an integrated circuit designed by Texas Instruments that serves as a UART with features and capabilities suitable for a wide range of applications from industrial and commercial to consumer applications. This article provides an overview of the TL16C554APN application field and its working principle.

The TL16C554APN is a 5V powered UART with low-cost and high performance. It includes advanced features such as intelligent handshake capability and more, with onboard programmable 65 byte FIFO. It is suitable for use in environments where high speed is required, such as high-speed modems and portable applications. The device has sixteen independent receive/transmit channels providing up to a total of eight independent communications ports in a single device.

The TL16C554APN is available in two distinct families, namely TL16C554APN[C/N] and TL16C554APN[CL/NL]. The former includes hardware flow control and the latter does not. Industry standard data transmission formats like 8/16-bit UART word lengths, odd/even/sticky parity and 5/6/7/8/9 bit stop are available in both families, providing maximum design flexibility. The TL16C554APN’s integrated FIFO allows multiple characters to be sent or received with greater reliability and fewer interrupts than other UARTs.

In terms of applications, the TL16C554APN can be used to construct applications such as the following: serial data acquisition systems, serial data communications systems, multi-frequency modems, high speed serial bus, and especially where low cost and high speed communication is critical, such as portable electronics, home automation, industrial controls, etc. Its integrated FIFO allows it to interface with other communication protocols and be used to build multi-port communication devices of various types, including network terminal servers, disk controllers, and multi-mode modems.

The TL16C554APN follows the UART principle of operation. The device includes two major components, the transmit register and the receive register. Data transmitted from the external device by the Transmit Register is placed in the Tx buffer. The receive register captures data from the receiver and places it in the Rx buffer. The device also includes an integrated FIFO that stores both data sent and received between the registers in the device. The device then sends both data stored in the transmit and receiver registers to the respective ports.

As part of its operation, the TL16C554APN includes various pin signals to indicate the start and end of packet transmission. It also includes a built-in error checking feature, allowing the device to detect errors in the transmitted or received data. Its integrated FIFO allows the device to efficiently store data, reducing delays and allowing higher data throughput. The device also includes programmable registers that allow users to set various communication modes according to their requirements.

In summary, the TL16C554APN is a powerful and low-cost UART device suitable for a wide range of applications. It includes many advanced features such as a versatile FIFO and error checking, allowing for higher performance and increased reliability. With its features and capabilities, the device is well suited for a wide range of applications, from industrial and commercial to consumer applications.
