The PB-ATOM-L+N455/D425/D525 is offered in three different CPU-variants. One version has the Intel Atom processor N455 with 1,66 GHz clock frequency 512MB 2L Cache and 667 MHz Front-Side- and memory bus, the Intel Atom processor D425 with 1,8 GHz clock frequency 512MB 2L Cache and 667 MHz Front-Side- and memory bus and the high performance version Atom processor D525 with 1,8 GHz dual core with 800 MHz Front-Side- and memory bus . Moreover both achievements have a 1MB L2-Cache and a SO-DIMM socket to mount up to 2GByte DDR3-RAM 667/800MHz.
The PB-ATOM-L+-N455/D425/D525 is based on the Intel Atom processors N455, D425 and D525, as well as the Intel ICH8M chipset. The performance is currently 1,66GHz to 2x 1,8GHz. The DDR3-RAM supports up to 4GB (D525) and is added via SO-DIMM socket. The graphic controller Intel GMA 3150 is integrated inside the Intel Atom processor and supports CRT displays up to a resolution of 2048×1536 (60Hz) and 18Bit LVDS displays up to a resolution of 1366×768. This interfaces are available: 2x RS232 (1x RS232, 1x RS232/422/485), 4x USB2.0, 1x SATA, 1x CFast socket and dual LAN 10/100/1000MBit as well as a high definition audio interface. Furthermore the board has a 16Bit ISA bus (PC/104) and a 32Bit PCI bus (PCI-104).
