GENERAL DESCRIPTION

The N3290x seires built on the ARM926EJ-S CPU core and integrated with JPEG codec, CMOS

sensor interface, 32-channel SPU (Sound Processing Unit), ADC, DAC, for meeting various kinds of

application needs while saving the BOM cost.

The combination of ARM926 @ 200MHz, synchronous

DRAM, 2D BitBLT accelerator, CMOS image sensor interface, LCD panel interface, USB 1.1 Host &

USB2.0 HS Device makes N3290x series the best choice for LCD ELA devices.

Maximum resolution for N3290 series is XVGA (1,024x768) @ TFT LCD panel. The 2D BitBLT

accelerator accelerates the graphic compution to make the rendering smooth and off-load CPU to save

power consumption.

The N3290x seires is well-positioned in terms of cost/performance for the applications which bitmap

graphics is extensively used or CMOS Image Sensor (CIS) interface is required.

The N3290x series is for application under Linux OS and leverage the driver availability of emerging

functionalities like Wi-Fi, browser, etc. On the other hand, the open source code environment also give

the product development more flexible.

To meet the different requirement of the overall system BOM cost, the different size of DRAM is

stacked with N3290x main SoC into one package, that is, multi-chip package (MCP). The N32901x

series particularly designed with 1Mbitx16 3.3V SDRAM. The N32903x series particularly designed

with 4Mbitx16 1.8V DDR SDRAM. One 16Mbitx16 1.8V DDR2 SDRAM stacked inside the N32905x

series to ensure higher performance and minimize the system design efforts, like EMI & noise

coupling. Total BOM cost could be reduced by employing 2-layer PCB along with the elimination of

damping resistors, EMI prevention components, etc. Advantages including, but not limited to, less PCB

space, shorter lead time, and higher / reliable production yield.
