The CP2110 is a highly-integrated HID USB-to-UART Bridge Controller providing a simple solution for updating RS-232 designs to USB using a minimum of components and PCB space. The CP2110 includes a USB 2.0 full speed function controller, USB transceiver, oscillator, one-time programmable ROM, and an asynchronous serial data bus (UART) in compact 4 x 4 mm QFN24 and 5 x 5 mm QFN28 packages (sometimes called “MLF” or “MLP”).
