SiLCP2102-GMR
Overview
The CP2102-GMR is a highly integrated USB-to-UART bridge controller that provides a simple solution for updating RS-232 designs to USB using minimum components. It includes a USB 2.0 full-speed function controller, USB transceiver, oscillator, and a UART with full modem control signals in a compact 5x5 mm QFN28 package. The device features an internal 1024-byte EEPROM for customizing USB Vendor ID, Product ID, and other descriptors without external memory.
Why Choose This Part
The CP2102 stands out for its ease of implementation, requiring no external quartz crystals or EEPROMs due to its integrated clock and internal 1024-byte programmable memory. It supports a wide range of baud rates and provides robust driver support for Windows, macOS, and Linux, ensuring plug-and-play compatibility across different operating systems. The small 28-QFN footprint and low typical supply current of 20mA make it ideal for space-constrained and power-sensitive applications.
Applications
Key Specifications
Getting Started
To begin development, download the Virtual COM Port (VCP) drivers from Silicon Labs to allow the device to appear as a standard COM port to the PC. The CP2102-GMR can be evaluated using various third-party breakout boards or the official Silicon Labs development kits. Engineers should ensure VDD is between 3.0V and 3.6V, though the VREGIN pin allows for 5V operation via the internal regulator.
