The adapter powered PXA270M DIMM PC - Development Kit Pro is based on the Marvell XScale® ARM® PXA270M processor. It is supplied in a stylish aluminium case that is able to accommodate a standard 2.5" IDE hard drive and via an analog VGA connector provides direct connectivity to generic CRT or TFT screens, supporting maximum resolution of 1024x768 pixels in a 16-bit color mode. PCMCIA interface, MMC/SD card and Compact Flash sockets significantly enlarge the possible usage of the development kit. AC'97 bus, used for high-definition audio data stream, also proved to be a very useful feature. Besides all the standard PC peripheral interfaces, the system provides multiple communication channels as well as universal expansion slots and connectors.
Several useful improvements were implemented, compared to the previous Voipac development kits, with these three upgrades being the most important:
• new PXA270M DIMM Module utilizes OneNAND Flash memory chip, allowing higher data transfer rate while increasing the maximum Flash memory size to 128MB
• improved AC'97 audio chip accuracy
• new JTAG cable with serial line for easier on-chip debugging, in-system programming and testing, available with schematic
