1 CH9101 Datasheet USB to Serial Port Chip CH9101 Datasheet Version: 1D http://wch.cn 1. Overview CH9101 is a USB bus converter chip which converts USB to asynchronous serial port. CH9101 provides standard MODEM signals, used to extend serial ports for computers, or upgrade directly from normal serial device to USB bus. Computer or other USB host VIO VDD5 CH9101 UD+, UD- UART/RS232/RS485 2. Features l Full-speed USB device interface, USB 2.0 compatible. l Built-in firmware, emulate standard UART interface, used to upgrade the original serial peripheral or expand additional serial port via USB. l Original UART applications are totally compatible without any modification in Windows operating systems. l Supports free installation OS which built-in CDC driver or multi-functional high-speed VCP vendor driver. l Hardware full duplex UART interface, integrated independent transmit-receive buffer, supports communication baud rate varies from 50bps to 3Mbps. l Supports 5, 6, 7, 8 data bits, supports odd, even, space, mark and no parity. l Supports common MODEM signals RTS, DTR, DCD, RI, DSR and CTS. l Supports CTS and RTS hardware automatic flow control. l Supports half-duplex, provides sending status TNOW which supports RS485 switching. l Supports RS232 interface, through external voltage conversion chip. l USB side supports 5V and 3.3V power supply voltages. l Serial port I/O powered independently, supports 5V, 3.3V, 2.5V and 1.8V power supply voltages. l Built-in power-on reset, built-in clock, no external crystal required. l CH9101U/H/Y/R integrates EEPROM, parameters such as chip VID, PID, maximum current value, vendor and product information can be configured. l Built-in Unique ID (USB Serial Number).
