Overview

The BM64SPKS1MC2-0003AA is a fully certified Bluetooth v5.0 dual-mode module designed for high-quality wireless audio and data applications. It integrates a 2.4 GHz transceiver, a DSP for audio processing, and an internal battery regulator into a compact 32mm x 15mm surface mount package. This module simplifies the addition of A2DP and SCO audio profiles to embedded systems with minimal external components.

Why Choose This Part

The module stands out for its high level of integration, including built-in battery monitoring ADCs and undervoltage protection, which reduces BOM cost for portable electronics. It offers robust performance with a high-resolution 20-bit audio interface and supports multiple digital interfaces like I2C, SPI, and UART for flexible host controller communication.

Applications

Bluetooth Audio Speakers
Utilizes the integrated DSP and A2DP profile support to stream high-fidelity wireless audio from smartphones or computers.
Wireless Headsets
Leverages the SCO link capability and voice call DSP functions for hands-free telecommunication devices.
Smart Home Hubs
Acts as a bridge between Bluetooth-enabled sensors or smartphones and a central gateway using its UART and I2C interfaces.
Portable Battery-Powered Devices
Takes advantage of the internal battery regulator, UVP protection, and 1.6uA sleep current for efficient power management.

Getting Started

To evaluate the module, designers can use the BM64 Evaluation Board along with the Microchip Bluetooth Audio Configuration Tool to modify DSP and UI settings. Hardware integration requires a 3.2V to 4.2V supply for VDD and careful placement of the integrated trace antenna away from ground planes for optimal RF performance.
