full-speed (12 Mbps) - USB suspend states supported via SUSPEND pins Asynchronous Serial Data BUS (UART) - All handshaking and modem interface signals - Data formats supported: - - Data bits: 5, 6, 7, and 8 - Stop bits: 1, 1.5, and 2 - Parity: odd, even, mark, space, no parity Baud rates: 300 bps to 1 Mbits 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 CP2103 External voltage supply or direct connection to VDD 5 VIO GPIO_0 GPIO_1 GPIO_2 19 18 17 16 (to external circuitry for status and control) 4 7 REGIN IN Voltage Regulator OUT GPIO_3 RST

Key Features

  • up to (4) 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. In many existing RS-232 designs, all that is required to update the design from RS-232 to USB is to replace the RS-232 level-translator with the CP2103. Direct access driver support is available through the Silicon Laboratories USBXpress driver set. See www. silabs. com for the latest.
