                                                                                                           AK37XXC

 

     AK37XXC processors are designed for a variety of advanced multimedia applications that typically require camera I/F, including Internet Protocol Cameras (IPCs), indoor surveillance cameras with TV-OUT and LCD display, and attendance machines.

 

     AK37XXC uses ARM926EJ-S core and integrates powerful video processor, image processor, audio ADC/DAC, USB2.0 Host/Slave controller, LCD display controller, MMC/SD controller, power management unit (PMU), Ethernet MAC, stacked SDRAM, and TV out into single system on chip (SoC), offering high multimedia performance and high system integration at reduced power consumption and cost of bill-of-materials (BOM). AK37XXC supports MJPEG codec (up to VGA@30fps, 720P@15fps), MPEG4 SP encoding (up to VGA@30fps), MPEG4 ASP decoding (up to VGA@30fps). Rich peripheral interfaces, including UART, IrDA, SPI, MMC/SD, SDIO and USB2.0, feature AK3760C with high extensibility and flexibility.

 

     A product development kit (PDK), including hardware development kit (HDK), software development kit (SDK) and tools (such as burn tool), is provided to accelerate product development.
