Dual Mode Stereo Audio SoC
Introduction
The IS2062/64 products are part of the Bluetooth Dual Mode family of stereo audio System on Chip
(SoC) devices.
• Flash-based devices:
– The IS2062GM and IS2064GM SoCs are offered in LGA packages and contain in-package
Flash, which allows for firmware updates.
• ROM-based devices:
– The IS2064S and IS2064B support Stereo Mode functionality in ROM. This allows for audio
playback on two devices. Some Bluetooth parameters can be customized and stored in an
internal EEPROM. These products are offered in QFN and BGA packages.
