Abstract: Universal Asynchronous Receiver Transmitter (UART) is usually an individual integrated circuit used for serial communication over a computer or peripheral device serial port. This UART is designed for make an interface between RS232 line and a microcontroller or an IP core. It works fine connected to a serial port of a PC for data exchange with custom electronic. UARTs are now commonly included in microcontrollers. A UART is a full duplex transmitter or receiver. UART is the kind of serial communication protocol. In parallel communication the cost as well as complexity of the system increases due to simultaneous transmission of data bits on multiple serial communications alleviates this drawback of parallel communication and emerges the effectively in many applications for long distance communication as it reduces the signal distortion because of its simple structure. The high speed UART is designed using verilog and delay is minimized (5.582ns). The synthesis of UART is done by using Xilinx 13.2 and simulation is done by ModelSim10.1.
