The XE143x series additionally includes an on chip voice CODEC as well as an fully integrated application controller, both are optimized for ultra low power consumption and low cost. The XE143x offers a high level of integration and with only a few external components a complete Bluetooth™ wireless headset solution can be built. By combining the XEMICS ''Bluetooth™ Headset device'' XE143x with a 3rd party 2.4GHz radio device ( e.g. Conexant CX72303) a real ultra low power Bluetooth™ headset consuming less than 35mW (HV3) @1.8V can be realized. |
