RK3528A is a high‑performance, highly‑integrated and low‑cost quad‑core application processor chip designed for Smart IPTV/OTT/DBS and high‑end multimedia applications. Its quad‑core Cortex‑A53 integrates dedicated Neon and FPU coprocessors along with a shared L2 cache to significantly boost system performance.
It embeds the ARM Mali‑450 GPU, which supports high‑resolution displays and provides full compatibility with graphics APIs including OpenGL ES 1.1/2.0 and OpenVG.
The RK3528A features a high‑performance 32‑bit external memory interface supporting LPDDR3/DDR3/DDR3L/DDR4/LPDDR4/LPDDR4X.
The advanced video decoder supports up to 10‑bit pixel 4K@60FPS UHD video playback, compliant with video standards such as H.265, H.264, VP9 and AVS2. The advanced video encoder enables 1080P@60FPS HD video capture with H.265 and H.264 encoding support.
The display controller allows flexible switching between HDMI output (supporting HDR10, VIVID HDR, CEC, HDCP2.2) and CVBS output.
The RK3528A also provides an extensive set of peripheral interfaces including SDMMC/SDIO/PCIE2.0/USB3.0/RGMII/I2S/PDM/UART/I2C/PWM/SPI, offering flexible support for a wide range of application scenarios.
