RK3506B is a high‑performance triple‑core Cortex‑A7 application processor designed for smart voice interaction, audio input/output processing, image output processing and other digital multimedia applications. It integrates a 2D hardware engine and display output engine to minimize CPU overhead and satisfy image display requirements. Embedded with abundant peripheral interfaces such as SAI, PDM, SPDIF, Audio DSM, Audio ADC, USB2 OTG, RMII, CAN, etc., the processor meets diverse application‑development requirements and reduces hardware‑development complexity and costs. The RK3506B features a high‑performance external memory interface (DDR2/DDR3/DDR3L) to meet stringent memory‑bandwidth requirements.
