Features l l l l l l l l l 480Mbps high-speed USB device interface, peripheral components only need crystal oscillator and capacitors. Built-in firmware, emulate standard UART interface, used to upgrade the original serial peripheral or expand additional UART via USB. Original serial applications are totally compatible without any modification in Windows operating systems. Hardware full duplex UART interface, integrated independent transmit-receive buffer, supports communication baud rate varies from 1200bps to 6Mbps. UART supports 8 data bits, supports odd, even, and none parity, supports 1 or 2 stop bits. Integrated the 2048-byte RX FIFO and 1024-byte TX FIFO for each UART. Supports common MODEM signals RTS, DTR, DCD, RI, DSR and CTS. Supports CTS and RTS hardware automatic flow control. Supports half-duplex, provides sending status TNOW, used for controlling RS485 to PDF
