Shenzhen Mingjiada Electronics Co., Ltd. supplies and recycles Bluetooth audio SoC of Zhongke Lancel BT8952F_BT8926B with high-performance 32-bit RISC-V processor

Chip Introduction

Bluetrum BT8952F Bluetooth Audio SoC, belonging to the "Bluetrum" three-generation BT895x series, is based on the 22nm advanced low-power process and supports Bluetooth 5.4 LE Audio protocol (all of which have been certified by the latest Bluetooth® Low Energy® Audio standard) and LE (Low Energy) Audio specification. Audio specification) and LC3 (Low Complexity Communication Codec) codec function.

Bluetrum BT8952F has a built-in 32-bit high-performance RISC-V processor core and HIFI 4 DSP, with a maximum processor speed of 125MHz and a maximum HIFI 4 speed of 270Mhz; built-in 16Mbits of Flash, 892KB of RAM, flexible GPIO pins with programmable pull-up and pull-down resistors; and support for wake-up or interrupt from GPIO.

Bluetrum BT8952F built-in 24bit dual-channel DAC (signal-to-noise ratio of 106dB, support for single-ended and differential mode) and 24bit mono ADC (signal-to-noise ratio of 103dB, support for single-ended and differential mode), support for flexible audio equalizer adjustments, support for 2-channel MIC amplifier inputs; BT8952F built-in acoustic plus plus a model of the dual-mic AI call noise reduction BT8952F built-in acoustic plus model dual-microphone AI call noise reduction algorithm, can realize dual-microphone beamforming call noise reduction, or 1 + 1 microphone call noise reduction; support feed-forward, feedback and hybrid active noise reduction; integrated built-in touch, PMU and other modules.

Bluetrum BT8926B Bluetooth audio SoC adopts a high-performance 32-bit RISC-V processor core with DSP instructions, maximum processor speed of 125MHz, built-in 8Mbit flash memory, 256KB RAM, flexible GPIO pins with programmable pull-up and pull-down resistors; it supports wake-up or interrupt of GPIO.

The BT8926B is compliant with Bluetooth 5.4 and BLE specifications, with TX maximum output power of +9dBm and RX sensitivity of -94dBm @2M EDR; supports TWS communication with balanced power consumption; and supports TWS master-slave switching. With high-performance mono DAC, signal-to-noise ratio of 98dB, support for single-ended mode or differential mode; single-channel high-performance ADC, signal-to-noise ratio of 90dB; support for mono MIC amplifier inputs; support for flexible audio equalizer adjustments; support for low-power touch keys, in-ear detection; built-in watchdog, integrated step-down and Li-Ion charging, which allows streamlined headset design.

Recycling specific process:

1.You will backlog of IC / module inventory for simple classification, determine the model, brand, production date, quantity, etc. .

2.Please send the inventory list to our evaluation team by fax or e-mail.

3. Wait for the company's professionals to make a purchase offer, after reaching an agreement, both sides will discuss the specific transaction mode for delivery.

4. The company only recycles formal channel sources, such as agents, traders, terminal factories, etc., and does not accept sources that are not formal channels.
