RK3168 - Dual-Core Cortex-A9 SoC | Rockchip | Mobile/Embedded
MPN: RK3168 ⚠ آخری بار خریداریRK3168 جائزہ
A SoC (System-on-Chip) is an integrated circuit that consolidates CPU cores, GPU, video codecs, display controllers, and peripheral interfaces on a single silicon die. Within the broader taxonomy, the RK3168 belongs to the application processor family, sitting between a microcontroller (no display/multimedia capability) and a full multimedia SoC. The Cortex-A9 microarchitecture places the RK3168 in the mid-2010s generation of ARMv7 application processors, which succeeded the Cortex-A8 and was later overtaken by Cortex-A53/A55 designs.
Key features include dual-core 1.2 GHz Cortex-A9 with out-of-order execution, PowerVR SGX540 graphics, integrated HDMI/LVDS display controllers, USB 2.0 OTG, MIPI CSI camera interface, multiple SDIO/EMAC/SD card controllers, and a hardware crypto block. The SoC is fabbed on a low-power process with typical smartphone power dissipation below 1 W, enabling fanless designs in tablets and set-top boxes.
Architecturally, the RK3168 uses a dual-core Cortex-A9 with NEON SIMD for media acceleration and a separate VPU (Video Processing Unit) that offloads 1080p decode from the CPU. This hardware partitioning delivers the multimedia performance of higher-priced application processors while maintaining the power profile of mobile devices. The SGX540 GPU provides OpenGL ES 2.0 and OpenVG 1.1 support suitable for 3D UI and casual gaming.
Typical applications include Android smartphones and tablets in the 7-10 inch class, Miracast/dongle wireless display adapters, low-cost media players and set-top boxes, in-vehicle infotainment (IVI) systems, and industrial HMI panels. The Miracast reference design (RK3168 + Wi-Fi companion chip) became a $10 retail adapter form factor in 2013.
When designing with this part, ensure the PCB stack-up meets the BGA escape routing requirements and provide adequate thermal relief on the package substrate. Designers should pair the RK3168 with LPDDR2 or DDR3 memory validated by Rockchip's hardware reference manual to avoid boot issues.

عام استعمالات
RK3168 کے لیے موزوں ہے 6 ایپلیکیشنs: Android Smartphones, 7-10 Inch Android Tablets, Miracast Wireless Display Adapters, Set-Top Boxes and Media Players, In-Vehicle Infotainment (IVI), Industrial HMI Panels.
Android Smartphones
The RK3168's dual-core Cortex-A9 at 1.2 GHz with PowerVR SGX540 GPU delivers the throughput required for Android 4.x smartphones in the entry-level to mid-range segment. Typical BOM integrates the RK3168 with LPDDR2 memory, eMMC storage, MIPI DSI LCD, MIPI CSI camera, and 3G/4G modem. The 1 W typical power dissipation supports all-day battery life in 1500-2000 mAh smartphone packs without active cooling.

7-10 Inch Android Tablets
The RK3168 drives 7-10 inch Android tablets targeting the entry-level and educational markets where cost dominates over peak performance. HDMI output supports external 1080p display mirroring for classroom projection, while the LVDS interface drives the integrated LCD panel. The fanless thermal envelope is maintained by the SGX540's modest 400 MHz clock and the dual-core CPU's 1.2 GHz limit.

Miracast Wireless Display Adapters
Rockchip's 2013 announcement specifically showcased the RK3168 in a $10 Miracast dongle reference design paired with a Wi-Fi companion chip. The hardware H.264 1080p decoder enables low-latency screen mirroring from Android and Windows devices, while the small BGA package allows the dongle to fit into HDMI-stick form factors. Power comes from the HDMI port or a single USB connector.

Set-Top Boxes and Media Players
The RK3168 powers entry-level Android set-top boxes and IPTV media players supporting 1080p H.264 decode of streaming video, HDMI output to the television, and USB 2.0 for external HDD media playback. The hardware video decoder offloads 1080p streams from the CPU, freeing the Cortex-A9 cores for UI rendering and network buffering.

In-Vehicle Infotainment (IVI)
The RK3168's hardware video decode and HDMI/LVDS dual-display support make it suitable for aftermarket in-vehicle infotainment systems featuring Android Auto-like interfaces. The 1 W typical power dissipation handles the thermal environment of head-unit enclosures, while the BGA form factor fits behind the LCD panel. Automotive AEC-Q100 qualification is not present, so aftermarket only.

ڈیزائن نوٹس
Estimated: At typical smartphone load (CPU 50% utilization, GPU 400 MHz, display ON), the RK3168 dissipates approximately 1 W. In a sealed tablet enclosure without active cooling, junction temperature rise is dominated by the BGA substrate thermal resistance. Designers should provide a thermal pad or copper pour under the BGA land area to keep Tj below 85 C ambient; derate performance if the enclosure exceeds 40 C ambient.
The BGA package requires careful PCB stack-up design: a 4-layer minimum with 0.8 mm or 0.65 mm BGA pitch demands microvia or via-in-pad escape routing. Use Rockchip's reference PCB gerber as a starting point, including the DDR3/LPDDR2 matched-length routing constraints documented in the RK30xx TRM. Failure to match DDR3 routing lengths causes boot failures and intermittent memory errors.
Do not attempt to reuse firmware images from the RK3188 or RK3028 on the RK3168 - the bootloader, device tree, and PMU initialization differ between Rockchip SoCs even within the same RK30xx family. Always use the firmware blob explicitly built for the RK3168 device tree. Substituting memory ICs outside Rockchip's validated memory list causes DDR3 training failures at first boot.
Place the RK3168 BGA, LPDDR2/DDR3 memory, and eMMC on the same PCB layer (typically top) to minimize via count on high-speed memory traces. Route HDMI differential pairs with 100 ohm differential impedance and length-matching within 5 mils. MIPI DSI/CSI lanes require 100 ohm differential with length-matching within 0.25 mm per the RK30xx TRM.
