Product Description
The ReadyBoard 800 is a mid-sized, EPIC-compatible, affordable, high quality single-board system,
which contains all the component subsystems of a PC/AT PCI motherboard plus the equivalent of
several PCI expansion boards. The ReadyBoard 800 is based on one of the ultra high performance,
high-integration Intel Pentium M or Celeron M processors. These processors with the matching chip set
give designers a complete integration solution with a high performance embedded processor based on
the EPIC form factor that conforms to the Revision 1.0 of the EPIC standard.
Each ReadyBoard 800 incorporates a Intel® 855GME chipset for the Graphics & Memory Hub
(Northbridge) and I/O Hub (Southbridge) controllers. This includes the Intel 82855GME Graphics &
Memory Hub, which controls the graphics and the memory interface and the Intel 82801DBM I/O Hub
Controller for I/O functions. The Winbond Electronics Corp. Super I/O controller, W83627HF, adds I/O
functions. Together, the Intel and Winbond chips provide four serial ports, a floppy or EPP/ECP parallel
port, four USB 2.0 ports, PS/2 keyboard and mouse interfaces, an Ultra/DMA 33/66 IDE controller
supporting two IDE drives and one compact flash socket, AGP 4X graphics equivalent controller, which
provides CRT and LVDS flat panel video interfaces for the most popular flat panels, and an audio
AC’97 CODEC on the board. The ReadyBoard 800 also supports two independent Ethernet interfaces,
10/100BaseT and 1000BaseT, and up to 1 GB of ECC or non-ECC DDR RAM in a single 200-pin
SODIMM socket.
The ReadyBoard 800 can be expanded through the PCI-104 expansion bus to accept PCI-104 cards that
offer compact, self-stacking, modular expandability for additional system functions. The PCI-104 bus
only implements the signal set for the PCI bus and is available on the 120-pin (4 rows of 30 pins)
expansion bus connector. If required for an application, the PC/104 bus, an embedded system version of
the signal set provided on a desktop PC's ISA bus, can be provided by the optional Ampro MiniModule
ISA expansion board. The PCI bus operates at 33 MHz clock speed and if included as an option, the
ISA bus operates at 8 MHz clock speed. See Figure 2-2.
Among the many enhancements provided on the ReadyBoard 800 to ensure system operation and
application versatility are a watchdog timer, serial console (remote access) support, battery-free boot,
customizable splash screen, on-board high-density compact flash card socket, and ACPI support for
sleep states.
The ReadyBoard 800 is particularly well suited to embedded applications by meeting the size, power
consumption, temperature range, quality, and reliability demands of embedded system applications. It
can be stacked with Ampro MiniModules™ or other PCI-104 compliant expansion boards, or it can be
used as powerful computing engine. The ReadyBoard 800 only requires a single +5V power supply.
