FAQ
1. What is RK3328?
RK3328 is a high-performance, low-power quad-core application processor from Rockchip, built on a 28nm process. It features a quad-core 64-bit ARM Cortex-A53 CPU and a Mali-450MP2 GPU, designed for 4K Ultra HD OTT/IPTV set-top boxes and digital multimedia devices.
2. What are the key specifications of RK3328?
Quad-core 64-bit ARM Cortex-A53 processor, up to 1.5GHz, with integrated Neon and FPU coprocessors and 256KB shared L2 cache; ARM Mali-450MP2 GPU supporting OpenGL ES1.1/2.0; supports 32-bit DDR3/DDR3L/LPDDR3/DDR4 memory.
3. What package does RK3328 use?
BGA316 package, measuring 14mm × 14mm with 0.65mm ball pitch.
4. What applications is RK3328 suitable for?
4K HDR OTT/IPTV smart set-top boxes, smart voice interaction devices (smart speakers, service robots), digital signage, facial recognition access control, smart self-service terminals, industrial automation terminals, soft routers, and NAS personal storage.
5. What development tools support RK3328?
Rockchip's Linux SDK (supporting Buildroot/Debian/Ubuntu/Yocto, etc.) and Android SDK (supporting Android 7.1). Official tools like rkdeveloptool are available for flashing and communication with Rockchip processors.
6. What is the operating temperature range of RK3328?
RK3328 standard version is commercial-grade with an operating range of 0°C to 70°C.
7. What is the video processing capability of RK3328?
