RTL8762DT-CG Realtek Bluetooth electronic component wholesalers

Realtek’s RTL8762DT-CG ultra-low power Bluetooth solution. The RTL8762DT supports Bluetooth 5.1, with a 90MHZ high frequency ARM Cortex M4F processor and high Flash memory. Its high integration is very suitable for the wearable market applications.

The RTL8762DT-CG provides the dual digital microphone design for the recording, which can record both human voice and ambient sound at a distance of about few meters. The recorded sound is then provided to the handset for noise reduction, resulting in a clear sound quality. The dual-mic recording mode for the convenience of recording anytime, anywhere.

Powerful computing power and ultra-low power consumption

The RTL8762DT-CG has a 90MHZ high-frequency ARM Cortex M4F processor with powerful computing power. It can record sound through the OPUS audio coding to obtain the best recording quality, and then transmit that recording to the cell phone via Bluetooth. The received clear audio file can be converted into many languages, or directly played in real time.

The battery’s endurance in the wearable device is an important consideration for user procurement. Realtek’s RTL8762DT has excellent low power performance. When the recording bracelet is fully charged at once, it can support long time of battery life, which not only becomes the highlight of the product, but also can effectively enhance the user’s experience.
