UARTs (Universal Asynchronous Receiver Transmitter) are one of the most widely used communication interface in embedded systems and PC applications. For instance, PC16552DV/NOPB is a serial communication device belonging to this family that plays an important role in serial switching, controlling, and data transfer activities.

The PC16552DV is a dual Universal Asynchronous Receiver / Transmitter (UART) device providing 5.0V TTL I/O and 3.3V LVTTL I/O levels. The device can be used in two independent UARTs for two-port applications or in combine mode for four-port applications such as dual RS-232 and dual RS-422 applications. Applications such as Automatic Call distributors, Automatic Message Handling Systems, X.21, ESCC, V.35 and other embedded systems can use this device for serial communication.

It is designed to accommodate the demanding telecommunications environment. As well as supporting high speeds, low-power consumption and small footprint, the PC16552DV/NOPB provides full-duplex (RS-232 and RS-422/RS-485) communication support with control and status signals that allow sophisticated system implementation.The integrated Spartan-6 LX16 FPGA features a 16K Gate capacity and is programmed via PCI to instantly change the operating mode and optimize communication throughput.

The PC16552DV/NOPB consists of two separate UARTs that each have their own transmitter and receiver, clock generator, FIFO, and control/status logic. It operates as an I2C slave device, allowing for faster data transfer between two ports. There is an input clock that is synchronized with an external clock that allows for low-power operation. It also reduces jitter and provides better accuracy for data transfers.

There is a Data Control register that is used to set various operating modes and data transfer rates. Additionally, a status register is provided that gives information about the current status of the device. Additionally, an 8-bit transmit and receive FIFO is provided for each UART,Allowing for data buffering in the UART and lowering the load on the external system.

The PC16552DV/NOPB also has a variety of advanced features, including an interrupt controller, error detection, and automatic baud rate detection. This allows it to be used in applications that require a higher level of accuracy.

Due to all these features, PC16552DV/NOPB is incredibly useful for a variety of applications. It offers fast data transfer rates, low power consumption, and low cost due to its small size.
