Detailed Description
The CMX655D is an ultra-low power voice codec targeted at digital voice and sensor applications that require the lowest possible power consumption, including battery powered and small form-factor applications.
Traditionally voice codes have interfaced to electret microphones and speakers providing A to D and D to A functions, using precision oversampling data converters.
Recent advances in microphone design using MEMS techniques are now changing this, along with higher efficiency speaker driver architectures such as Class D topologies. Both of these advances enable significant reductions in power consumption which is needed to address new applications such as voice control, that require always-on operation. Such applications that are often battery powered, driving the need for ultra-low power consumption.
The EV6550DHAT brings the benefits of MEMS (Micro-Electro Mechanical System) microphone technology and the CMX655D voice codec to the Raspberry Pi.
