SiLCP2108-B03-GM
Overview
The CP2108-B03-GM is a highly integrated USB-to-Quad-UART bridge controller that provides a simple solution for updating RS-232 or RS-485 designs to USB. It features four independent UART interfaces and 16 GPIOs in a single 9x9 mm QFN64 package, operating from a 3V to 3.6V supply. The device eliminates the need for external crystals or resistors, significantly reducing BOM count and PCB footprint.
Why Choose This Part
The primary advantage is the integration of four UARTs into one chip without requiring firmware development or external timing components. It includes 512 bytes of programmable EEPROM for custom VID/PID and serial numbers, and its 16 configurable GPIOs allow for hardware handshaking or custom status indicators. Silicon Labs provides royalty-free VCP drivers, ensuring broad compatibility across Windows, macOS, and Linux.
