CH340C USB to Serial Port Chip CH340C SOP-16
1. Introduction
CH340 is a USB bus converter chip which converts USB to serial port or printer port.
In UART mode, CH340 provides standard MODEM signals, used to extend serial port for computers, or upgrade directly from normal serial device to USB bus. For more information about converting USB to printer interface, please refer to the CH340DS2 datasheet
2. Features
- Full-speed USB device interface, USB 2.0 compatible.
- Emulate standard UART interface, used to upgrade the original serial peripheral or expand additional UART via USB.
- Original UART applications are totally compatible without any modification in Windows operating systems.
- Hardware full duplex UART interface, integrated transmit-receive buffer, supports communication baud rate varies from 50bps to 2Mbps.
- Supports common MODEM interface signals RTS, DTR, DCD, RI, DSR and CTS.
- Provides further RS232, RS485, RS422 interface, etc. through external voltage conversion chip.
- CH340R supports IrDA criterion SIR infrared communication, supports baud rate varies from 2400bps to 115200bps.
- Built-in firmware, software compatible with CH341, use VCP driver of CH341 directly.
- Supports 5V and 3.3V power supply voltages.
- CH340C/N/K/E/X/B have integrated clock, no external crystal required, CH340B also integrates EEPROM used to configure the serial number, etc.
- RoHS compliant SOP-16, SOP-8, SSOP-20 and ESSOP-10, MSOP-10 lead-free package.
Package Type : SOP-16
