ST16C554DCJ68-F is a universal asynchronous receiver-transmitter (UART) chip designed for use in asynchronous communication systems. It is capable of operating with a wide range of standard baud rates from 1200-115200 bps depending on the model. The ST16C554DCJ68-F is a highly integrated single-chip UART that improves the reliability of data transmission and reduces the external components needed for a complete solution. The device provides a full-duplex 9-bit synchronous/asynchronous serial port and is suitable for both full-duplex synchronous communication and simplex asynchronous communication.

The ST16C554DCJ68-F offers various features such as programmable clocks, a data-rate generator, a TX/RX encryption engine, and an integrated FIFO buffer. The device supports an adjustable 15-character buffer for data transmitted/received in both directions and a 115,200bps baud rate. The ST16C554DCJ68-F was designed with an operating temperature range of -40°C to +85°C.

Applications of ST16C554DCJ68-F include:

• Serial communication systems such as RS-232, RS-485 and IrDA.
• Industrial automation.
• Modems, barcode scanners and other consumer electronics.
• Automobile telemetry and data acquisition.
• Other embedded applications.

The ST16C554DCJ68-F has two communication modes to support asynchronous or synchronous data transfer. Both the hardware and software UARTs can operate in asynchronous mode. This mode allows data to be transmitted without the need for any synchronization between the transmitting and receiving devices. The UART sample data from the receiving side and transmits them on the transmitting side.

The synchronous mode supports bidirectional, half-duplex operation. In this mode, data is transmitted in 8-bit frames, with the start and stop bits being used to differentiate between actual data and the start/stop markers. A synchronous UART can operate in master and slave modes. In master mode, the UART sends a synchronization signal and then sends data over the line. In slave mode, the UART receives the synchronization signal and then waits to receive the incoming data.

The ST16C554DCJ68-F can also be used to provide an alternative to RS-232 in terms of its electrical interfaces. The device has a fully bidirectional data bus with programmable pins that can be used to connect the signal lines of transmitters and receivers. A maximum TX/RX signal frequency of up to 115200bps can be achieved with the ST16C554DCJ68-F.

The ST16C554DCJ68-F also supports other features such as auto-flow control for easy data transmission, programmable baud rates, transmission and receive line status detection, transmit/receive interrupt control, and error checking using parity, frame and CRC. It also supports auto-flow control, a hardware control line in the hardware UART.

In summary, ST16C554DCJ68-F is an ideal solution for serial communication applications, offering a wide range of features and reliable data transmission at high baud rates. With its wide operating temperature range and a host of features, the ST16C554DCJ68-F chip is suitable for various interface communication applications such as RS-232, RS-485, IrDA and other embedded systems.
