CX20921-99Z Description

Short technical summary and product information.

The CX20921-99Z from Conexant Systems is a sophisticated System-on-Chip (SoC) designed for far-field voice input processing. This device integrates a voice trigger function, enabling a low-power Wake-on-Voice (WoV) capability. In WoV mode, with the ADC and DSP active, the device consumes less than 70mW, significantly below typical standby power requirements.

 

Key features include a powerful dual-core 32-bit DSP, multiple Integrated Interchip Sound (I2S) serial data interfaces, and an Inter-Integrated Circuit (I2C) serial control interface. The CX20921 is compatible with various embedded and server-based speech recognition engines and vendors.

 

This voice input processor is suitable for a range of applications, including voice-controlled Smart TVs and STBs, smart Bluetooth/WiFi speakers, voice-interactive smart appliances, Internet of Things (IoT) devices, and automotive hands-free control systems. The component is housed in a 60-QFN 7mm x 7mm package.
