Qualcomm QCA6234

The QCA6234 chip is a complete, small form factor 2x2 802.11 a/b/g/n WLAN plus BT4.0 combo solution optimized for low-power embedded devices. The device integrates all WLAN and Bluetooth (BT) functionality in a single package to support a low cost, layout-friendly implementation while allowing flexibility for platform specific customization.

The QCA6234 chip integrates the complete transmit/receive RF paths including baluns, switches, and a reference oscillator. The device is also pre-calibrated, eliminating the need for customer production calibration.

QCA6234 supports Bluetooth 2.1 + EDR and Bluetooth low energy (Bluetooth 4.0) standards enabling seamless integration of BT/WLAN and Low Energy technology. A flexible BT RAM/ROM split architecture enables optional customization to meet customer specific needs and use cases. Ultra-low power consumption radio architecture and proprietary power save technologies extend battery life. Embedded on-chip CPUs handle complete 11n and BT MAC/BB/PHY processing to minimize host processor loading.

QCA6234 is available in three variants:
- QCA6234X: 2x2, dual-band 802.11n and Bluetooth 4.0 (SDIO)
- QCA6234XH: 2x2, dual-band 802.11n and Bluetooth 4.0 (HSIC)
- QCA6234XU: 2x2, dual-band 802.11n and Bluetooth 4.0 (USB)

QCA6234 is available in a low profile 9.2 mm x 9.2 mm LGA package with 0.65 mm pitch pads for low-cost PCB design. It is halogen-free, Pb-free, and fully ROHS compliant.
