System Overview
1.1 Introduction
The ROBO-8710VLA all-in-one full size single board computer is designed to fit high
performance and scalable Intel entium 4/Celeron processors and compatible for
high-end industrial computer system with CI plus ISA local bus architecture
( ICMG 1.0 Rev 2.0). It is made to meet today’s demanding reliability & stability for
critical computing environments, and keep complete compatibility & functionality
for wide range of applications. It’s beneficial to built up a high performance and
reliable system for VARs, or system integrators. The on-board 3D ATI-Mobility
Radeon graphics with panel display interface and TV output interface, Intel fast
Ethernet interface and AC-97 audio CODEC will bring full functionality and high
performance to all segments of the industrial C market.
This single board computer runs with Intel® entium® 4/Celeron (m GA478)
processor, and supports two DIMM up to 2GB DDR SDRAM maximum. The
enhanced on-board CI IDE interface can support 4 drives up to IO mode 4 timing
and Ultra DMA/33/66/100 synchronous mode feature. The on-board Super I/O
Chipset integrates one floppy controller, two serial ports, one keyboard controller,
hardware monitoring, one IrDA port and one parallel port. Besides, three USB
(Universal Serial Bus) ports provide high-speed data communication between
peripherals and C.
Its proprietary CI extension connector provides an easy way to add additional
functions like U160 SCSI or 2nd LAN device in minutes. The compact form factor
with proprietary CI connection interface makes it the best and flexible daughter
board solution for adding more functions in a limited space.
The ICMG standard makes the ROBO-8710VLA works with the legacy ISA,
ISA/ CI or multi-slots CI-bus backplane. The on-board 32-pin DI socket supports
M-systems DiskOnChip 2000 product up to 512MB. The Watch-Dog Timer function
can be used to restart you system whenever system goes abnormal. One 6-pin
Mini-DIN connector (with Y-Cable) is provided to connect S/2 Mouse and
Keyboard. The on-board Flash ROM is used to make the BIOS update easier, ROM
chip can be replaced quickly. The ROBO-8710VLA also provide up to 8 high driving
G IO and high-resolution watchdog timer. All of these features make
ROBO-8710VLA excellent in many applications and one of the best performing single
board computer in the market.

1.4 System Architecture
The most up-to-date system architecture of ROBO-8710VLA includes two main Intel
chips, Intel 845E chipset supports entium-4 processor, DDR-SDRAM, 2D/3D
graphic display, and its 82801BA ICH2 supports CI bus interface, A M, AC I
compliant power management, USB port, SMBus communication, and Ultra
DMA/33/66/100 IDE Master, and it also provides a Fast Ethernet controller.
W83627HF (I/O Controller) is responsible for S/2 Keyboard/Mouse, UARTs, FDC,
Hardware Monitor, arallel, Watch Dog Timer and Infrared interface.
The special pin configuration of the C U socket adopts the 478 pins in total. This new
generation C U provides better performance to many applications.
The CI-to-ISA bridge supports a standard 16-bit ISA bus interface which is applied
for all slower I/O operations. In ROBO-8710VLA, it supports DiskOnChip (DOC) for
M-systems Flash disk.
There is one on-board CI Fast Ethernet via RJ-45 orts to support full functionality
of ROBO-8710VLA AIO SBC (All-In-One Single Board Computer). The on-board
68-pin CI connector supports one additional CI daughter board for further
extension.

Notes:
1) All General urpose I/O ports can only adapt standard TTL ± 5% signal level
(0V/5V). in 1~4 can be either input or output, while pin 6-10 can only be digital
output.
2) The 4 extra DO ports are provided for the applications that need higher driving
capability. Through invert amplitude respected to G IO port, each open-drain
DO port can stand maximum fan out for up to 100mA, rather than 12mA direct
driven by G IO port.
