1 EM3288 Introduction
1.1 Summary
EM3288 is a single board computer based on the Rockchip RK3288, Quad Core Cortex-A17 @1.8GHz.
RK3288 is powerful on multithreaded computing operation, graphics processing and video decoding
ability. RK3288 supports Mali-T760 MP4 Graphics Processing, OpenGL ES1.1/2.0/3.0, OpenVG1.1,
OpenCL, Directx11, and can 4Kx2K archieve 4kx2k H.264 and 10 bits of H.265 video decoding, 500%
performance boost over Mali-400. On display aspects, RK3288 supports up to 18Gbps Data transmission
rate and 4Kx2K@60Hz Video resolution.
It is implemented with a MINI3288 computer-on-module providing most of the functions and interfaces,
and EM3288_C carrier board providing connectors and several additional functions. The rich feature set
of EM3288 is customizable according to the price / performance needs of the target application. EM3288
contains expansion connectors which accommodate a wide range of standard peripheral devices. Wide
input range switched power supply is compatible with requirements for telecom and automotive
applications. EM3288 is provided with full ready-to-run Android4.4.4 and Ubuntu SW packages and
comprehensive user manual and designing guide.
1.2 Rockchip RK3288 Features
The first SoC with real 4Kx2K video decoder
The first SoC with total solution for HDCP2.x security.
RK3288 is a high performance application processor for high-end tablet, notebook, all-in-one device,
smart monitor and TV-Box. Especially it is one of most powerful solution for 4Kx2K TV-Box.
Integrate quad-core Cortex-A17 with separately Neon and FPU coprocessor, also shared 1MB L2 Cache.
More than 32bits address will support up to 8GB access space.
Currently, latest generation and most powerful GPU is embedded to support smoothly high-resolution
(3840x2160) display and mainstream game. Support OpenVG1.1, OpenGL ES1.1/2.0/3.0, OpenCL1.1,
RenderScript and DirectX11 etc.
Full-format video decoder, including 4Kx2K multi-format decoder.
Lots of high-performance interface to get very flexible solution, such as multi-pipe display with
dual-channel LVDS, dual-channel MIPI-DSI, eDP1.1, HDMI2.0 , dual-channel MIPI-CSI2 interface with
13MP ISP embedded.
Fully-integrated hardware-based security solution will provide HDCP2.x for miracast and all kinds of DRM
solution based on different OS.
Dual-Channel 64bits DDR3/LPDDR2/LPDDR3 provide demanding memory bandwidths for
high-performance and high-resolution application.

2.6 HDMI (PH1)
The HDMI interface available is based on the “HDMI transmitter” & “HDMI 3D Tx PHY” integrated into the
EM3288 SoC. The “HDMI transmitter” combines video/display data from the IPU, Audio data from
EM3288 memory & control/status data from the ARM complex, into Xhdmi data & clock channels. The
“HDMI 3D Tx PHY” transmits the combined data by means of 3 Xhdmi data pairs and an Xhdmi clock pair
to the EM3288 carrier board interface.
EM3288 HDMI2.0 supports maximum 4Kx2K display, and it also enables HDMI/LCD audio and video
synchronization output. The HDMI interface is the regular 19pins HDMI type A, with width 13.9mm and
thickness 4.45mm. The resolution up to 1920x1080p@60HZ.
