Introduction

AI Translation

The CP2102/9 is a highly-integrated USB-to-UART Bridge Controller providing a simple solution for updating RS232 designs to USB using a minimum of components and PCB space. The CP2102/9 includes a USB 2.0 fullspeed function controller, USB transceiver, oscillator, EEPROM or EPROM, and asynchronous serial data bus (UART) with full modem control signals in a compact 5 x 5 mm QFN-28 package. No other external USB components are required. The on-chip programmable ROM 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 programmable ROM 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 CP2102/9-based product to appear as a COM port to PC applications. The CP2102/9 UART interface implements all RS-232 signals, including control and handshaking signals, so existing system firmware does not need to be modified. In many existing RS-232 designs, all that is required to update the design from RS-232 to USB is to replace the RS232 level-translator with the CP2102/9. Direct access driver support is available through the Silicon Laboratories USBXpress driver set.

Product FAQ

  • 1. What internal controllers, clocking components, and USB functions are integrated into the CP2102?
    The Silicon Labs CP2102 is a highly integrated USB 2.0 full-speed (12 Mbps) USB-to-UART bridge controller. It integrates a USB function controller, USB transceiver, calibrated internal 48 MHz oscillator, on-chip 3.3 V voltage regulator, power-on reset circuit, and an internal 1024-byte EEPROM. The device requires no external crystal or USB resistors for USB communication, helping minimize external components and PCB space.
  • 2. What operating voltages, power modes, and current consumption does the CP2102 support?
    The CP2102 supports both bus-powered and self-powered operation. In bus-powered mode, the REGIN pin accepts 4.0 V to 5.25 V from the USB bus, while self-powered designs supply 3.0 V to 3.6 V directly to the VDD pin. The on-chip voltage regulator provides a nominal 3.3 V output and can supply up to 100 mA to external circuitry. Typical operating current is 20 mA, while typical suspend current is 80 µA (bus-powered with the regulator enabled).
  • 3. What UART baud rates, data formats, and flow-control options are supported?
    The CP2102 UART supports programmable baud rates from 300 bps up to 921600 bps. It includes a 576-byte receive buffer and a 640-byte transmit buffer, and supports 5-, 6-, 7-, or 8-bit data, 1, 1.5, or 2 stop bits, and odd, even, mark, space, or no parity. Hardware flow control (RTS/CTS and DSR/DTR), modem interface signals (DCD and RI), and software XON/XOFF handshaking are also supported.
  • 4. What package and operating temperature specifications apply to the CP2102?
    The CP2102 is available in a RoHS-compliant 28-pin QFN package measuring 5.0 mm × 5.0 mm and is specified for operation over an industrial temperature range of −40°C to +85°C.
  • 5. What EEPROM customization features and assembly recommendations are provided?
    The CP2102 includes an internal 1024-byte EEPROM that can be programmed over USB to customize the USB Vendor ID (VID), Product ID (PID), Product Description String, Power Descriptor, Device Release Number, and Device Serial Number for OEM applications. For PCB assembly, Silicon Labs recommends using the JEDEC/IPC J-STD-020 reflow profile for small-body components.
