N3291xUxDN Data Sheet
1. GENERAL DESCRIPTION
The N3291xUxDN is specially designed for accelerating video stream decoding performance while off-loading the
CPU to save power consumption. It is embedded H/W video decoder to deliver high-quality video playback in different
formats, like H.264 / MPEG-4 / H.263.
The N3291xUxDN is built on the ARM926EJ-S CPU core and integrated with video encoder, JPEG codec, CMOS
image sensor interface, Sound Processing Unit (SPU), ADC, DAC, and TV encoder for meeting various kinds of
application needs while saving the BOM cost. The combination of ARM926 @ 300MHz, DDR2, H/W video decoder,
and USB2.0 HS Device makes the N3291xU1DN the best choice for high performance media processing devices.
The N3291xU1DN also integrates an AES cipher/de-cipher cryptography engine for stream protection considerations.
The stream stored in SD card, SPI NOR Flash, or NAND Flash is encrypted. It is decrypted when the stream is read
back and decrypted for playback.
The N32916UxDN is ported with Linux OS to leverage the driver availability of emerging functionalities, like Wi-Fi
connectivity. On the other hand, the open source code environment also gives the product development more
flexibility. Moreover, hybrid platform is introduced to best utilize the performance advantage at native C programming
while enjoying the inherent benefit at application firmware/software development.
Maximum resolution for the N3291xUxDN is D1 (720x480) @ TV output and 1,024x768 @ TFT LCD panel. With
increasing popularity of the application image resolution, the N3291xUxDN is the best fit for the application that
requires fast turn-around time of development. The N3291xUxDN is well-positioned in the cost effective & high
performance media player market where video streams are extensively used.
To reduce system complexity while cutting the BOM cost, the N3291xUxDN is particularly designed with the 128-pin
SLQFP MCP (Multi-Chip Package). For N3291xUxDN, the 32Mbitx16 DDR2 chip is stacked inside the MCP to ensure
higher performance, lower power consumption and to minimize the system design efforts, like EMI and noise coupling.
The N3291xUxDN is incorporated with a reliable Linux OS kernel and Board Support Package (BSP) to help
customers shorten the design cycle time. The fast booting time (under 3 seconds), from power on to application
running, is another extra feature to help eliminate power consumption.
