Product Description
The LittleBoard 735 is an exceptionally high integration, high performance, rugged, and high quality single-
board system, which contains all the component subsystems of a PC motherboard plus the equivalent of up
to 3 expansion boards. Based on the Intel Atom N270 low power, high-integration processor, the
LittleBoard 735 gives designers a complete, high performance, embedded processor based on the EBX form
factor and conforms to the EBX V2.0 specifications.
Each LittleBoard 735 incorporates an Intel 945GSE chipset for the Graphics and Memory Hub
(Northbridge) and the I/O Hub (Southbridge) controllers. This set includes the 82945GSE, Graphics and
Memory Controller Hub, (also GMCH), which controls the graphics and memory interface. The other chip
in this set is the 82801GBM, I/O Controller Hub 7 Mobile (ICH7-M), which controls some of the I/O
functions on the board. One additional chip provides the remainder of the I/O functions: the Standard
Microsystems, SCH3114I-NU, Super I/O controller. Together the Intel and SMSC chips provide four serial
ports, an EPP/ECP parallel port, six USB 2.0 ports, PS/2 keyboard and mouse interfaces, floppy, one Ultra/
DMA 33/66/100 IDE controller supporting Compact Flash, two independent 10/100/1000BaseT Ethernet
interfaces, an audio AC’97 CODEC, PCIe Mini Card, GPIO, SMBus, and two SATA ports on the board. To
provide the ISA bus on the board through the PC/104 connector, an ITE IT8888G-L, PCI-to-ISA Bridge is
included. The LittleBoard 735 also supports up to 2GB of DDR2 RAM in a single 200-pin SODIMM slot,
and a Graphics Media Accelerator (GMA), which provides VGA, TV Out, and LVDS flat panel video
interfaces for most LCD panels and CRT monitors.
The LittleBoard 735 can be expanded through the PC/104 and PC/104-Plus expansion for additional system
functions, as these buses offer compact, self-stacking, modular expandability. The PC/104 and PC/104-Plus
buses are the embedded system versions of the signal set provided on a desktop PC’s ISA and PCI buses at
8MHz and 33MHz clock speeds, respectively.
Among the many embedded-PC enhancements on the LittleBoard 735 that ensure embedded system
operation and application versatility are a Watchdog Timer, serial console support, battery-free boot, on-
board, high-density Compact Flash socket, and BIOS extensions for OEM boot customization.
The LittleBoard 735 is particularly well suited to either embedded or portable applications and meets the
size, power consumption, temperature range, quality, and reliability demands of embedded system
applications. It can be stacked with ADLINK MiniModules™ or other PC/104-compliant expansion boards,
or it can be used as a powerful computing engine.
