Description

The CH340G is a USB-to-TTL converter that allows devices with a USB interface to communicate with UART-based devices using standard TTL voltage levels. The chip is widely used in various embedded systems, development boards, and DIY electronics. It offers a low-cost and efficient solution for USB to serial communication, with a focus on supporting systems that communicate over UART (Universal Asynchronous Receiver/Transmitter).

Features

  • USB to TTL Conversion: Converts USB signals to TTL-compatible serial signals and vice versa.
  • Wide Voltage Support: Supports devices with 3.3V or 5V logic levels for serial communication.
  • Baud Rate Support: Supports baud rates up to 1 Mbps for data transfer.
  • Driver Compatibility: Works with Windows, Linux, and macOS with readily available drivers.
  • Simple Interface: Provides the basic TX, RX, VCC, and GND pins for serial communication.
  • Low Power Consumption: Low operating current suitable for battery-powered designs.
  • No External Components Required: The CH340G doesn’t require external components like crystals or oscillators, which simplifies the design process.
  • SOP-16 Package: Compact, space-efficient packaging for use in embedded systems with limited PCB area.

Specifications

  • Package: SOP-16 (Small Outline Package – 16 pins).
  • Input Voltage: Works with 3.3V or 5V logic devices.
  • Baud Rate: Up to 1 Mbps.
  • USB Protocol: Full-speed USB 2.0 (12 Mbps).
  • Operating Voltage: Typically operates with a 5V USB supply.
  • Data Interface: Standard UART interface with TX, RX, VCC, and GND.
  • Temperature Range: Operating range from 0°C to 70°C.
  • Power Consumption: Efficient, with typical power consumption around 500 µA in idle mode.
