PXA255 is Low power, high performance 32-bit Intel XScale® core-based CPU (200, 300 and 400 MHz). The SoC is ARM Architecture v.5TE compliant. 0.18µ process for high core speeds at low power.
Your ePlatform Partner User’s Manual for Advantech SOM-A2552 series module V1.00 CPLD SOM-A2552 series have one CPLD on board. The CPLD take charges of the following function: l System memory assignments l I/O control l RTC control Base on Advantech policy, Advantech won’t release the CPLD code to user. In fact, when user designs their own target carrier board, they don’t need to know the CPLD code. Advantech will release memory map of available memory block and available GPIOs.
