RK3368 Descripción general
What is an application processor SoC? An application processor SoC (System-on-Chip) integrates the CPU, GPU, memory controller, video decoder/encoder, display pipeline, and connectivity peripherals onto a single silicon die. In the broader taxonomy: SoC -> application processor -> microprocessor unit (MPU) -> semiconductor. Rockchip positions the RK3368 in its 64-bit octa-core family below the RK3399 (big.LITTLE A72+A53) and above the entry-level RK3328 (quad-core A53).
Key features include 64-bit ARMv8 instruction set with full AArch64 execution, hardware H.265 Main Profile decoding up to 4K@60 Hz with H.265 Main10 support, OpenGL ES 3.1 / OpenCL 1.2 capable Mali-T720MP2 GPU running at up to 600 MHz, USB 2.0 host and OTG ports, Gigabit Ethernet MAC, and a flexible VOP (Video Output Processor) supporting HDMI 2.0, eDP, and MIPI-DSI. The integrated Cortex-A53 cores provide 2-3x the performance-per-watt of the previous-generation Cortex-A7 used in the RK3288.
The RK3368 architecture uses a single homogeneous octa-core cluster with coherent L2 cache, simplifying software scheduling compared to big.LITTLE designs. The 28 nm process keeps idle power low, while the integrated LPDDR3 controller with 32-bit width and 800 MHz clock provides up to 6.4 GB/s memory bandwidth suitable for 4K video decode.
Typical applications include 4K Android TV boxes, OTT streaming sticks, smart signage players, industrial HMI panels, and education tablets. The Cortex-A53's power efficiency also makes the part suitable for fanless enclosures.
Design consideration: the RK3368 requires careful 4-layer or 6-layer PCB stack-up with matched-length DDR3 traces and a robust PMIC (RK806 or compatible). LPDDR3 routing demands 100 ohm differential impedance; deviations will cause read/write errors at high temperatures.

Aplicaciones típicas
RK3368 es adecuado para 6 aplicacións: 4K Android TV Box, OTT Streaming Stick, Smart Signage Player, Industrial HMI Panel, Education Tablet, Set-Top Box with DVR.
4K Android TV Box
The RK3368 was the first 64-bit octa-core SoC purpose-built for Android TV boxes, with hardware H.265 Main10 decode up to 4K@60 Hz and HDMI 2.0 TX that streams 3840x2160 directly to the display. The Mali-T720MP2 GPU runs OpenGL ES 3.1, enabling Android TV UI animations and casual gaming at full 4K. Its 1.5 GHz Cortex-A53 cluster provides ample headroom for the Android launcher, DRM-protected streaming (Widevine L1 with proper integration), and concurrent background apps. Typically paired with 2 GB DDR3 and 16 GB eMMC for mainstream TV box SKUs.
Recomendado
OTT Streaming Stick
The RK3368's low idle power (~0.5 W at idle per Rockchip measurements) and small 19x19 mm BGA package make it suitable for compact streaming-stick form factors where the SoC, DRAM, eMMC, Wi-Fi module, and PMIC must fit on a single 4-layer PCB. The Cortex-A53 efficiency supports passive (fanless) cooling even at full 4K HEVC decode load. H.265 hardware decode avoids CPU bottlenecks, leaving the A53 cores free for app logic and DRM handling.
Recomendado
Smart Signage Player
The RK3368 drives dual-screen signage via HDMI 2.0 + MIPI-DSI simultaneous output (depending on firmware), decoding 4K H.265 video loops and rendering HTML5 overlay graphics using the Mali-T720MP2 GPU. Commercial operating range (0 C to +80 C) supports enclosed kiosk installations. Eight A53 cores allow concurrent management of media playback, remote CMS polling over GbE, and sensor inputs without frame drops.
Recomendado
Industrial HMI Panel
The RK3368's commercial temperature grade, 64-bit Cortex-A53 cores, and hardware video decode fit industrial human-machine interface (HMI) panels running Linux or Android for factory automation. Its GbE MAC supports real-time EtherCAT/Profinet gateway designs when paired with an external ASIC. The octa-core cluster enables concurrent Qt/Web HMI rendering, data logging, and network protocol stacks without missing display refresh deadlines at 60 Hz.
Recomendado
Education Tablet
The RK3368 powers education-tablet designs targeting K-12 and reading applications, where its 64-bit Cortex-A53 cores run Android with sufficient performance for interactive learning apps while keeping BOM cost low. The Mali-T720MP2 GPU supports educational games and AR overlays via the MIPI-CSI camera input. Long battery life is achievable thanks to A53's power efficiency versus older A7/A9 designs used in legacy tablets.
Recomendado
Set-Top Box with DVR
The RK3368 enables set-top boxes with simultaneous 4K H.265 decode and H.264 encode for DVR/time-shift functionality. The Cortex-A53 cores handle transport stream demuxing, CAS/DRM, and EPG while the VPU handles the encode pipeline. GbE MAC supports IPTV multicast (IGMPv3) and MoCA 2.5 coexistence. Typical designs pair the RK3368 with a tuner demodulator and 2-4 GB DDR3.

Notas de diseño
The RK3368 BGA-453 package requires a minimum 4-layer PCB stack-up with a dedicated ground plane adjacent to the BGA and matched-length (within 25 mil) DDR3 traces. Use 100 ohm differential impedance for DDR3/LPDDR3 routing and route clock signals on inner layers with continuous ground reference. Route HDMI TX pairs on the top layer with ground-side shielding; avoid routing HDMI across splits in the ground plane. Decoupling: 100 nF X7R ceramic per power pin plus 22 uF bulk on each major rail (VDD_CPU, VDD_GPU, VDD_LOGIC).
Estimated: at full 4K H.265 decode + 1.5 GHz CPU + 600 MHz GPU load, the RK3368 dissipates approximately 2-3 W. With the BGA-453 lid (theta_JA approx 15-20 C/W for a properly designed 4-layer board), junction temperature rises 30-60 C above ambient. A small thermal pad (10x10 mm) bonded to a chassis heatsink is recommended for fanless enclosures operating above 35 C ambient. Verify thermals with a thermocouple on the BGA lid during worst-case sustained video decode.
Do not attempt to use the RK3368 without the companion RK806 PMIC - the SoC requires precise rail sequencing (VDD_LOGIC before VDD_CPU before VDD_GPU) that discrete regulators cannot reliably provide. Avoid using DDR3L when the PMIC is configured for DDR3 (voltage mismatch will cause memory errors at high temperature). Do not populate the BGA with no-clean flux only; bottom-terminated components require underfill or corner staking to survive drop/shock tests in TV box enclosures.
MIPI-DSI and MIPI-CSI lanes are highly sensitive to impedance discontinuities. Route each lane on the top layer over a continuous ground plane with 100 ohm differential impedance, and keep lane-to-lane length matching within 0.5 mm. HDMI 2.0 TX pairs must meet the tighter 85 ohm differential (vs. 90 ohm for HDMI 1.4) - ensure your PCB stack-up is designed accordingly. Source termination on HDMI is built into the RK3368; do not add external series resistors.
