According to statistics, the total shipments in 2017 exceeded 400 million units, and the audio market share exceeded 50%. Support BLE4.2+classic bluetooth dual-mode.

Application areas: Bluetooth story machine, pure Bluetooth speaker, card-plug Bluetooth speaker, large speaker with pull rod, car Bluetooth, AI smart speaker, point reading pen (voice emission, serial code, magic sound function).

1. Brief introduction of Jerry Bluetooth chip AC6901A

AC6901A is a single-chip Bluetooth solution launched by Jerry in December 2016. It is packaged in LQFP48 and supports MP3 and WAV. At the same time, it also supports the decoding of lossless formats FLAC and APE, and 24-bit DAC output. It integrates Bluetooth + plug-in card + radio, and the version of Bluetooth is 2.1+EDR. It can be said that this chip is a powerful chip that is the best choice for developing a plug-in card Bluetooth speaker.

Jerry’s AC690N series chips are all in one wafer, but they are packaged in different ways according to different needs, that is to say, the AC6901A (LQFP48) and AC6905A (SSOP24) packaged wafers in the AC690N series are the same, AC6901A The chip can be programmed repeatedly. Its operating voltage range is: 3.3V~5.5V, and the theoretical power consumption is 20~25mA. The specific power consumption is related to the functions of the product. This power consumption value is for reference only.
