RK3308B‑S is a high‑performance quad‑core application processor designed for intelligent voice interaction, audio input/output processing and other digital multimedia applications. It integrates abundant audio interfaces such as I2S, PCM, TDM, PDM, SPDIF and HDMI ARC to meet various audio application development requirements, reducing hardware development complexity and costs. The embedded voice activity detection function monitors human voices in real time, responds promptly to voice requests and enables rapid development of intelligent voice‑interaction applications. It also lowers system power consumption and improves battery life. RK3308B‑S features a high‑performance external memory interface (DDR2/DDR3/DDR3L/LPDDR2) to sustain demanding memory bandwidth. RK3308H‑S comes with embedded 64 MB DDR2, while RK3308H1‑S integrates 128 MB DDR3L.
