The AlphaBlue SoC IP is an ARC 605-based SoC, integrated with MindTree’s BlueWiz Baseband Controller, timers, Watch Dog Timer, GPIO, SPI/12C and system controllers. AlphaBlue offers high levels of optimization in gate area and power for Bluetooth® headsets and hands-free applications. The integrated firmware and application software is based on enhanced ANSI C drivers to provide the lowest memory footprint possible. With the optional ClearMind Acoustic Echo Cancellation and Noise Reduction (AECNR) software from MindTree, a high-end hands-free product can be built with no additional BOM costs. Thus, the AlphaBlue SoC IP provides an evolved, low-cost solution for the design & development of headsets and hands-free applications.
