GeneralPlus GP3300 Cortex A8 Processor and Android Tablet Reference Design

I’ve recently come across Eken D70 Tablet which is a typical 7″ Android ICS tablet, except it’s product description shows a Cortex A8 chip called GP33003.

GeneralPlus GP3300xA Tablet Reference Design

After some research, I found that this chipset is provided by GeneralPlus (previously part of Sunplus). GP3300x application processor features a cortex A8 clocked at 1 GHz together with a PowerVR SGX531 GPU, and comes in 216pins LQFP package.  This SoC integrates LVDS and HDMI, and the company told me that the GP33XX targets “higher resolution displays, but still keep the lower PCB cost, compared to its current competitors”.  It also features an hardware video decoder and encoder (up to 1080p), and can handle a 720p full-duplex video conference. That’s about all the information I could get about the SoC itself. I’ll update this post If I find out more.

The company also provides a tablet reference design (GP3300xA Tablet) with the following specifications:

  • SoC – GP3300x Cortex A8Cortex [email protected] + SGX531 GPU.
  • Memory – 512MB DDR RAM.
  • Storage – 4GB NAND Flash + SD card slot (up-to 32GB).
  • Display – 800×480 7″ capacitive touch LCD panel
  • Sensor – 3-axis Acceleration sensor.
  • Connectivity – Wi-Fi (802.11b/g/n) and Bluetooth (EDR2.0)
  • USB – USB 2.0 Host and mini USB 2.0 Device port.
  • Battery – 2000mA Lithium-ion for 3 hours usage (Android home screen with LCD-panel on, WiFi off) and 120 hours standby.
  • Audio I/O – Headphone jack, Built-in speaker and microphone
  • Camera – VGA CMOS sensor.
  • Video Output – HDMI (Full HD 1080p) and composite video output (D1)

The company provides Linux 2.6.35 and Android 4.0.2 ICS with this demo kit.

    Thre is no way this tablet to support 1080p.
    [email protected] + SGX531 GPU cannot handle 1080p.
    I have [email protected] + SGX540 GPU and 1080p is out of the question for it.

    Like with AllWinner A10, it’s likely video decoding is not handled by the GPU, but a separate video decoder / encoder.

    @ Demetris
    Yes, It’s better to see some 1080p tests before purchasing such device. AFAIK, it’s not available at the retail level yet (even on aliexpress).

    My beef with Generalplus is, in comparison with the bigger players like Allwinner and Mediatek, stuff for it like source codes and other documentation is, like with its previous parent company Sunplus, hard to come by.
