CX20921-21Z Description

Short technical summary and product information.

The CX20921-21Z from Conexant Systems is a sophisticated voice input processor System-on-Chip (SoC). Designed for far-field voice applications, it integrates a voice trigger function enabling a low-power Wake-on-Voice (WoV) mode. In WoV mode, with the ADC and DSP active, the device consumes less than 70mW, meeting stringent 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. This makes it compatible with various embedded and server-based speech recognition engines and vendors.

 

Applications for the CX20921-21Z include voice-controlled Smart TVs and Set-Top Boxes, smart Bluetooth/WiFi speakers, voice-interactive smart appliances, Internet of Things (IoT) devices, and automotive hands-free control systems.

 

The device is supplied in a 60-QFN 7mm x 7mm package.
