Silicon Lab USB upgrades Bird's cell phone interface cable

The CP2101 USB microcontroller from Silicon Laboratories Inc. has been adopted by Chongqing Bird Technology Co. Ltd for its new cellular phone interface cable. The CP2101 upgrades Chongqing Bird's UART, RS232 and RS485 systems to USB.

The CP2101 includes a complete USB 2.0 full-speed function controller, bridge control logic and a UART interface with transmit/receive buffers and modern handshake signals. The device also features on board EEPROM, a voltage regulator, a USB transceiver and an integrated internal oscillator, eliminating external components typically required in USB applications.

"The CP2101 leverages our expertise in integrating precision analog and high-performance digital to deliver highly integrated MCU solutions," said Derrell Coker, VP of Silicon Laboratories.
