Silicon Labs' new USBXpress controller simplifies USB connectivity for embedded designs

Silicon Labs (Shenzhen Core Technology Co., Ltd., NASDAQ: SLAB) announced the release of the newest member of the USBXpressTM bridge family, the CP2102N USB Bridge, which offers smaller size, lower power consumption and a simpler and faster way. Add a universal serial bus (USB) connection to a new or original embedded design. Silicon Labs' new CP2102N USB controller eliminates complex, time-consuming firmware development and offers more advanced features in a tiny 3mm x 3mm QFN package. The CP2102N bridge simplifies USB-to-UART connectivity and speeds time-to-market for a wide range of portable, power-sensitive and space-constrained applications such as USB adapters, point-of-sale (POS), data loggers, game controllers and Personal medical equipment, etc.

With the rapid adoption of USB in embedded designs, developers are looking for a faster, more economical way to add USB connectivity to their applications. Silicon Labs' highly integrated CP2102N USB-to-UART bridge provides a simple, direct replacement solution for adding USB to new designs, and also enables existing RS-232 designs with minimal device count and PCB area Upgrade to USB. Silicon Labs' proven architecture eliminates expensive off-chip crystals and reduces resistance and other components. Silicon Labs' fixed-function bridges integrate USB 2.0 full-speed controllers and UART interfaces in a single-chip solution, dramatically reducing space constraints. Limit bill of materials (BOM) costs in the application.

The CP2102N Bridge is one of Silicon Labs' lowest power USB connectivity solutions, offering <10mA low operating current, which extends battery life for power sensitive applications. Advanced features such as integrated remote wake-up, USB battery charge detection allow the device itself to wake up the suspended host and detect the type of charger connected to the system, further reducing BOM cost.

The CP2102N bridge eliminates the need for USB protocol expertise or time-consuming firmware and driver development, allowing developers to focus more time and resources on their end application design. The CP2102N is pin and software compatible with Silicon Labs' existing CP210x USB devices, so customers can easily migrate to the latest USB-to-UART bridging technology. These fixed-function devices are ideal for USB connections that require embedded design with minimal development effort, or for applications that require a traditional serial interface (such as a UART) to be upgraded to USB.

Tom Pannell, director of product marketing for Silicon Labs MCU, said: "USB has become the interface of choice for countless embedded applications, but from a developer's perspective, USB is a complex protocol that requires considerable firmware expertise and development effort. Silicon Labs The latest USBXpress bridging devices provide a highly integrated, turnkey solution for adding USB to new embedded designs or upgrading existing designs to USB, especially for portable, space, power and battery life limited applications. application."

Silicon Labs is a leading provider of USB connectivity solutions offering a broad range of flexible USB products, including fixed-function devices and general-purpose 8-bit and 32-bit MCUs with on-chip USB controllers.

Simplicity Studio tool accelerates time to market

Silicon Labs' latest release of the Simplicity Studio development environment includes built-in support for USBXpress bridge device development, which greatly simplifies the development of USB connectivity in embedded applications. With an easy-to-use, GUI-based Xpress Configurator tool, developers can use it to quickly configure and program the desired USB-to-UART parameters to generate the required customizations that the factory can use to produce. The license-free virtual COM port (VCP) device driver enables the device to present a COM port for use by PC applications. To further accelerate development, Silicon Labs also offers the CP2102N-EK evaluation development kit supporting the CP2102N USB Bridge, which includes an integrated debugger for configuration, easy-to-access GPIO and UART connector plugs, and battery charger detection pins. And remote wake-up button.
