≤he dual-core architecture with flash memory enables
manufacturers to easily differentiate their products with
new features without extending development cycles.
≤he enhanced Kalimba DSP coprocessor with up to
120 MIPS supports more digital signal processing
requirements in stereo headphones, headsets, gaming
headsets and soundbars.
≤he audio codec supports 2 ADC channels, up to 6
microphone inputs, stereo output and a variety of audio
standards.
