                                                                                                                    AK39XX

 

Aiming to provide high multimedia performance and high system integration at reduced power consumption and cost of bill-of-materials of end products, the AK39XX series processors use ARM926EJ-S core and integrate DDR2 SDRAM, camera interface, Image signal Processor (ISP), Video/Image processor, audio ADC/DAC, USB2.0 controller, MMC/SD controller into single system on chip (SoC).

 

In addition, a product development kit (PDK), including hardware development kit (HDK), software development kit (SDK) and tools (such as testing tools for mass production), is provided to accelerate product development.
