BES2300-Z芯片简介

        BES2300-Z is a highly integrated SoC with Bluetooth 4.2+5.0 dual mode and high performance Cortex-M4F for wireless audio and voice application. It is also optimized for FWS (Fully Wireless Stereo) application, which is BES’s stereo connection technology between primary and secondary Voice Box.

      

        BES2300-Z minimizes the external components and BOM cost by highly integrating RF transceiver, high performance audio codec and Cap-less headphone driver。 It also integrates serial Flash and powerful Cortex-M4F MCU to support various software features and product customization。 BES2300-Z is manufactured with advanced 28nm low power CMOS process and assembled with a 4。5*6。2mm 80-ball BGA package。




BES Solutions Competitive Advantages
• Open and powerful platform
➢ RF/Analog/PMU/Audio/CPU/RAM/Flash fully Integrated
➢ ARMTM Cortex-M4F Run Up to 400MHz
➢ Flexible Interface: USB Type C, I2S, SPDIF, UART, I2C, SDIO…….
➢ Up to 32Mb psram and 32Mb flash to support rich software features 
➢ Standard gcc tool chain and easy development
• Advanced low power technology process
➢ The first company to adopt 28nm for Bluetooth audio SOC in the world.
➢ Efficient power management technology including DVFS to reduce power consumption
• LBRT:Low Band Bluetooth Retransmission Technology
➢ Low Band(10-15MHz) Bluetooth Retransmission Technology bring the better music and communication experience. ➢ BES patented LBRT can make the bit rate up to 3Mbps

Advantage for Low Band Bluetooth Retransmission

                     

   Ideal for cross-head        Anti 2。4G interference    Under water application     High throughput for audio

User experience is the key point for a successful products.
• 2。4GHz signal would drop too much when it cross the head
• 2.4GHz interference is too heavy in subway, conference and exhibition center, airport.
• The compatibility of the dual a2dp/sco link is limited, because of the different mobile phone baseband。
• BES patent: retransmission the Bluetooth signal by low band, but can support higher data rate(3Mbps) to transmission the music。


BES LBRT Comparison with Traditional FWS


LBRT Advantage:

① More stable

② Perfect performance for audio drop ③ Low power Cons

④ Low latency

⑤ High bit rate 3Mbps for music

⑥ Good for health

Weakness:

① Need to add a low frequency antenna
