Description
The CX20921 is a high-performance, far field voice input processor System-on-Chip (SoC). The device is the first product in this category with an integrated voice trigger function that supports a low system power Wakeon-Voice (WoV) function.
When ADC and DSP are active in the Wake-on-Voice (WoV) mode, the device consumes less than 70mW, which is well below the 0.5W European Commission (EC) 1275/2008 requirement for standby power.
