Realtek has officially launched the first universal SDK (v3.14.0.39) specifically designed for the RTL87x3D series Bluetooth chips. The RTL87x3D series is a single-chip Bluetooth audio solution that integrates an MCU and DSP, utilizing the latest Bluetooth® Core Specification v5.4 protocol. It achieves superior performance through an ARM Cortex-M4 core and two ultra-low-power DSP cores. The chip is equipped with Hi-Fi Mini for voice and audio codec functions, and Hi-Fi 4 to support high-performance signal processing and software neural network libraries.

Realtek has just released a new version of the RTL87x3E MCU General SDK (v3.13.0.90). This version introduces several new features and updates, which we hope will be beneficial to you.

Bluetooth audio technology has made significant advancements over the past few decades and is widely used in various consumer electronic devices. Codec offloading, an important technology in modern Bluetooth audio devices, is becoming increasingly popular. It enhances device performance and efficiency by shifting the computational tasks of audio encoding and decoding from the main processor (CPU) to dedicated hardware components or coprocessors.
