The CP2102-GMR from Silicon Labs is a versatile single-chip solution for USB to UART data transfer, simplifying the process of connecting legacy serial devices to modern USB interfaces. This device integrates a USB transceiver and clock, eliminating the need for external resistors and crystals. It features an internal 1024-byte programmable ROM, allowing customization of vendor ID, product ID, serial number, power descriptor, release number, and product description strings. Additionally, the CP2102-GMR includes an on-chip power-on reset circuit and a 3.3 V output voltage regulator, ensuring reliable operation and compatibility with a wide range of applications.
Compliant with USB Specification 2.0 and supporting full-speed data transfer at 12 Mbps, the CP2102-GMR offers robust USB functionality with suspend state support via SUSPEND pins. The UART interface supports various data formats, including multiple data bits, stop bits, and parity configurations, with baud rates ranging from 300 bps to 1 Mbps. It also features substantial buffer sizes—576 bytes for receive and 640 bytes for transmit—along with hardware or X-On/X-Off handshaking. The device is compatible with existing COM port applications on various operating systems, including Windows, Mac OS, and Linux, and offers a royalty-free distribution license for its Virtual COM Port and USBXpress™ drivers.
