CPU introduction

  • i.MX28 series of multi-media application processor is the latest member of Freescale ARM9 series of items.i.MX28 series of items combine unique display,power management and connection speciaty based on ARM9,reduce the cost and complexity of system for the application sensitive to the budget.
  • Tool and software easily used will facilitate you designing unique products in terms of industrial control and consumer electronics in a shorter period of time, i.MX28 features optimized function and power consumption,which is very suitable to be used in the systems without fans and portable devices powered by battery. It provide multiple options for connection functions,including dual 10/100 ethernet(support IEEE?1588) based on L2 exchange function.which can meet the special demands in industrial application,moreover,its connection functions of CAN,USB and ethernet can completely meet the demands in automotive industry.
  • i.MX28 care about the overall cost of system, it combines physical USB interface(PHY),10/100 ethernet,power management and displayed controller in resistance touch screen,so it can provide economic and highly effective solutions for products in automotive grade.e.g it can used for monitor in highway toll station,,CAN gateway,accessory of automotive audio)USB or SD card adaptor) and car radio controlled by touch screen.designer can lay out many creative and visual user interfaces through LCD controller with touch screen.
