Product Descriptions

RK3328 is a high-performance Quad-core application processor designed for Smart STB (Set Top Box) including OTT/IPTV/DVB. It is a high-integration and cost efficient SOC for 4K HDR STB.

Quad-core Cortex-A53 is integrated with separate Neon and FPU coprocessor, also with shared L2 Cache. The Quad-core GPU supports high-resolution display and game.

Lots of high-performance interface to get very flexible solution, such as multi-channel display including HDMI2.0a and TV Encoder (CVBS). TrustZone and crypto hardware are integrated for security. 32bits DDR3/DDR3L/DDR4/LPDDR3 provides high memory bandwidth.
