interfacing rs 232 with spartan 6 fpga


Posted on Feb 7, 2014

The UART (universal asynchronous receiver/transmitter) is a serial protocol with separate transmits and receives lines, and can be used for full duplex communication. The Spartan-6 board has 2 Serial Port, indicated as in Figure. RS-232 serial communication is performed through a 9-pin SUB-D connector and the FPGA UART module. The UART is one of t

he most common ways of exchanging data between the FPGA and peripheral components. In order to enable this communication, it is necessary to establish a connection between RX and TX lines on SUB-D connector and the same pins on the target FPGA. Since RS-232 communication voltage levels are different than FPGA logic levels, it is necessary to use a RS-232 Transceiver circuit, such as MAX3232 as shown in Figure.
