Atmel ATEVK1105 Digital Audio Gateway kitAddressing the need for increased digital audio functionality in devices, the AVR32 ATEVK1105 Digital Audio Gateway kit from Atmel uses AVR AT32UC3A 32-bit Flash microcontrollers to create systems for digital audio streaming, decoding and playback. The AVR32 CPU’s DSP functionality handles audio decoding and the UC3A handles two audio interfaces with a stereo 16-bit bitstream audio DAC with internal FIR and Comb filters. For 4-channel or full surround sound, an IIS interface is available for connection to an external audio codec. Both interfaces are supported with drivers that use the AVR32 peripheral DMA controller to significantly reduce CPU overhead. From $179.
