　　Summary

　　The IS2064 products are part of our Bluetooth Dual Mode family of stereo audio SoCs. Three variants are offered in a variety of packages, form factors and memory configurations. The IS2064GM is a Flash-based device that can be programmed to support a variety of speaker configurations. The IS2064S/B are ROM-based devices featuring Stereo Mode functionality, which allows audio playback on two devices.

　　All variants support SBC and AAC Codecs. The IS2064GM-0L3 supports LDAC. For more information contact your local Microchip representative or send an email to BTAudio@microchip.com.
