Overview

Jz4750 is one power-efficient and cost-efficient 32-bit embedded processor with high integration,  high performance and powerful multimedia processing, supporting mobile SDRAM and 12/8 bits ECC Nand flash. It is targeted for mobile consumer applications like PMP, Mobile TV and education electronic devices.   Jz4750 features Ingenic's innovative XBurst CPU core, running at 360 MHz frequency and highly optimized for the lowest power consumption and the lowest cost. It integrates Video engine, audio codec, TV encoder and abundant peripherals, supporting MPEG2/MPEG4/WMV D1 resolution decoding and Rm/Rmvb 1024x576 or little bigger resolution decoding. With Linux and WinCE supporting, Jz4750 can be applied into lots of embedded products such as PMP, education electronic device, fingerprint identification, E-book, baby monitor and more.
