CP21 Series Bridges

Cost sensitive bridge solutions from Silicon Labs

Image of Silicon Laboratories' CP21 Series Bridges The latest additions to Silicon Labs' industry-leading Smart Interface family are the CP2104, CP2105, CP2110, and CP2112 connectivity bridges. These devices extend Silicon Labs' portfolio to include cost sensitive USB to UART, USB to dual UART, HID-USB to UART, and HID-USB to SMBUS/I2C bridge solutions. Common to all these devices are royalty-free software driver suites, crystal-less operation, in-system programming memory, and small 4 mm x 4 mm packages, which in combination reduce cost, simplify design, and shorten development time.

The high-performance, low cost CP21xx USB to UART bridge family offers a complete plug and play interface solution that includes royalty-free driver suites and a comprehensive design ecosystem that enables customers to speed time to market. Crystal-less operation, in-system programming memory, and small body size packages reduce cost, simplify design and shorten development time.
