Product Descriptions

RK3308 is a high-performance Quad-core application processor designed for intelligent voice interaction, audio input/output processing, and other digital multimedia applications. 

Embedded rich audio interfaces, such as I2S, PCM, TDM, PDM, SPDIF, HDMI ARC and so on, can meet different audio application development, reduce hardware development complexity and development cost.

Embedded Voice Activity Detection function will monitor human voice at any time, respond  to human voice request timely and fast setup intelligent voice interaction application, which  will also reduce hardware system power consumption and improve battery endurance.

RK3308 has high-performance external memory interface (DDR2/DDR3/DDR3L/LPDDR2) capable of sustaining demanding memory bandwidths.
