USBXpress Family CP2102N Data Sheet The CP2102N devices, part of the USBXpress family, are de- KEY FEATURES signed to quickly add USB to your applications by eliminating firmware complexity and reducing development time. No firmware development required Simple GUI-based configurator These highly-integrated USB-to-UART bridge controllers provide a simple solution for Integrated USB transceiver no external updating RS-232 designs to USB using a minimum of components and PCB space. resistors required CP2102N includes a USB 2.0 full-speed function controller, USB transceiver, oscillator, Integrated clock no external crystal and Universal Asynchronous Receiver/Transmitter (UART) in packages as small as 3 required mm x 3 mm. No other external USB components are required for development. All cus- tomization and configuration options can be selected using a simple GUI-based config- USB 2.0 full-speed compatible urator. By eliminating the need for complex firmware and driver development, the Data transfer rates up to 3 Mbaud CP2102N devices enable quick USB connectivity with minimal development effort. USB Battery Charger Detection (USB BCS 1.2 Specification) CP2102N is ideal for a wide range of applications, including the following: Remote wakeup for waking a suspended Medical equipment POS terminals host Data loggers USB dongles Low operating current : 9.5 mA Gaming controllers Royalty-free Virtual COM port drivers CP2102N USB Battery Remote Voltage 48 MHz Charger External Wakeup Regulator Oscillator Detect circuitry for USB Connector USB suspend states 960 byte USB USB Function Hardware Configuration Transceiver Controller Handshaking Memory External battery External RS-232 charging transceiver or circuitry UART circuitry 512 byte 512 byte UART RS485 TX Buffer RX Buffer Feature is related to: USB UART Overall System silabs.com Building a more connected world.
