CP2103 USB to TTL Converter

CP2103 SMD USB-to-TTL Bridge Controller

The CP2103 is a highly-integrated USB-to-UART Bridge Controller providing a simple solution for updating RS-232/RS-485 designs to USB using a minimum of components and PCB space. The CP2103 includes a USB 2.0 full-speed function controller, USB transceiver, oscillator, EEPROM, and asynchronous serial data bus (UART) with full modem control signals in a compact 5x5 mm QFN-28 package (sometimes called “MLF” or “MLP”). No other external USB components are required.

The on-chip EEPROM may be used to customize the USB Vendor ID, Product ID, Product Description String, Power Descriptor, Device Release Number, and Device Serial Number as desired for OEM applications. The EEPROM is programmed on-board via the USB, allowing the programming step to be easily integrated into the product manufacturing and testing process. Royalty-free Virtual COM Port (VCP) device drivers provided by Silicon Laboratories allow a CP2103-based product to appear as a COM port to PC applications. The CP2103 USB to UART interface implements all RS-232/RS-485 signals, including control and handshaking signals; so, existing system firmware does not need to be modified. The device also features up to four GPIO signals that can be user-defined for status and control information. Support for I/O interface voltages down to 1.8 V is provided via a VIO pin.

Features of CP2103 USB ro TTL IC

  • Integrated USB transceiver; no external resistors required

  • Integrated clock; no external crystal required

  • Integrated 1024-Byte EEPROM for vendor ID, product ID, serial number, power descriptor, release number, and product description strings

  • On-chip power-on reset circuit

  • On-chip voltage regulator : 3.3 V output

  • Baud rates : 300 bps to 1 Mbps

  • 576 Byte receive buffer; 640 byte transmit buffer

  • Hardware or X-On/X-Off handshaking supported

  • Four GPIO signals for status and control

  • Configurable I/O (1.8 V to VDD) using VIO pin

  • Configurable I/O (VDD to 5 V) using external pull-up

  • RS-485 mode with bus transceiver control

  • Self-powered : 3.0 to 3.6 V

  • USB bus powered : 4.0 to 5.25 V

  • I/O voltage : 1.8 V to VDD

Applications of CP2103

  • Upgrade of RS-232 legacy devices to USB

  • Upgrade of RS-485 legacy devices to USB

  • Cellular phone USB interface cable

  • PDA USB interface cable

  • USB to RS-232 serial adapter
