Single chip bluetooth case

AK1050T adopts ARM926EJ-S core, integrated audio codec, Bluetooth transceiver, USB2.0 slave controller, and power management unit (PMU) as a single-chip system (SOC), providing powerful multimedia performance under the premise of reducing power consumption And highly integrated system (BOM). A set of peripheral interfaces, including UART, SPI, IrDA, I2S, and USB2.0, have high scalability and flexibility.

AK1050T is Ankai's single-mode single-chip Bluetooth IC based on Bluetooth V2.1+ EDR protocol, highly integrated application and high performance. Using it to develop can effectively control costs. Bluetooth stereo speakers can be realized through this chip solution! The AK1050T IC is equivalent to integrating the functions of the two ICs of the AK1055C V2.1 Bluetooth module "AK1055C+RDA5876" into one IC. The functions that AK1050T can realize are the same as those of AK1055C V2.1.
