Enhance Graphic Chip SMI SM501 introduction
The SM501 is a Mobile System-on-a-Chip (MSOC™ ) device. This robust device delivers high-performance video and 2D operation, providing a solution for embedded mADKets. The SM501 also contains a wide variety of I/Os, such as analog RGB and digital LCD Panel interfaces, an 8-bit parallel interface, USB, UART, IrDA, Zoom Video, AC97 or I2S, SSP, PWM, and I2C interfaces. These built-in functionalities help to reduce overall system cost. Additional programmable GPIO bits can be used to interface to external devices as well.

System Memory
SOM-A2552 SDRAM can be configured as 4/8/16/32/64/128/256MB. Users can base on their requirement to reconfigure the SDRAM size.
There are two functions Flash on SOM-A2552 series. One is Boot Flash, the other is Storage Flash.
Boot Flash is 1MB NOR flash. In standard SOM-A2552 series product, Advantech will pre-install the WinCE bootloader in it.
Storage Flash is used to save image & user APs. Storage Flash size is also reconfigurable. The Storage Flash is M-system Flash. Storage Flash size could be 0/16/32/64 MB. SOM-A2552 series have Multiple boot options through the on-board Flash or Compact Flash Card (CFC) for easy maintain and cost saving. If Storage Flash is 0MB that means user should put the image in Compact Flash Card.
