N32926U1DN

8KB 80 ARMOther series 240MHz LQFP-128(14×14) Microcontroller Units (MCUs/MPUs/SOCs) ROHS

The N3292x is built on the ARM926EJ-S CPU core and is integrated with video codec (H.264), Ethernet MAC, JPEG
codec, CMOS sensor interface, 32-channel SPU (Sound Processing Unit), ADC, DAC and TV encoder for saving the
BOM cost in various kinds of application needs. The combination of ARM926 @ 240MHz, DDR2, H.264 codec, AAC
accelerator, SDIO host controller and USB2.0 HS Host/Device makes the N3292x be the best choice for video/audio
streaming devices.
Maximum resolutions for N3292x are D1 (720×480) @ TV output and 1024×768 @ TFT LCD panel. With the increasing
popularity of video streaming resolutions, H.264 is the best fit for limited bandwidth application that requires smaller data
rate for high-resolution video. The N3292x is well designed in terms of cost/performance for the video/audio streaming
market where Wi-Fi, Ethernet or proprietary RF is extensively used. For 2.4GHz proprietary applications, the hardware
CRC generator and checking engines will off-load CPU loading to save the power consumption. Moreover, the hardware
channel coding engines including scrambler, inter-leaver, Reed-Solomon outer codec and convolutional inner codec
engines are used for more reliable wireless video/audio data streaming in the crowd 2.4GHz ISM band environment.
To reduce system complexity while cutting the BOM cost, the N3292x also provides versatile options of MCP (Multi-Chip
Package). The 32Mbx16 or 16Mbx16 DDR2 is stacked inside the MCP to ensure higher performance and to minimize the
system design efforts, such as EMI, noise coupling. Total BOM cost could be cut by employing 2-layer PCB along with the
elimination of damping resistors, EMI prevention components and less board space
