Introduction CHAPTER 1 Introduction The ROBO-538 all-in-one single board computer is designed to fit a high performance Pentium-based CPU and compatible for high-end computer system with PCI Local Bus architecture. It is made to meet today’s demanding pace, and keep complete compatibility with hardware and software designed for the IBM PC/AT. It's beneficial to build up a high performance and high data availability system for VARs, or system integrators. The optional on-board IEEE-1394 provides one high – speed interface port with data transfer rate 400Mbits/s. This single board computer can run with Intel Pentium or compatible processor up to 333 MHz, and support DIMM up to 256MB DRAM. The enhanced on-board PCI IDE interface can support 4 drives up to PIO mode 4 timing and Ultra DMA/33 synchronous mode feature. The on-board Super I/O Chipset integrates floppy controller, two serial ports, one IrDA (Standard & Fast Infrared) port and one parallel port. Two high performance 16C550-compatible UARTs provide 16-byte send/receive FIFOs, and the multi-mode parallel port supports SPP/EPP/ECP function. Besides, two USB (Universal Serial Bus) ports provide high-speed data communication between peripherals and PC. The PICMG standard makes the ROBO-538 works with the legacy ISA, ISA/PCI or multi-slots PCI-bus backplane. The three on-board 32-pin DIP sockets support M-system Disk-on-Chip products up to 432MB, and one PC/104 interface provides flexible embedded platform. The Watch-dog Timer function can monitor your system status. Two 6-pin Mini-DIN connectors are provided to connect PS/2 Mouse and Keyboard. The on board Flash ROM is used to make the BIOS update easier. A standard P8 power connector is reserved for getting more power energy in high power applications, the additional 5-pin shrouded connector is reserved for connecting Keyboard interface on the backplane. The high precision Real Time Clock/calendar is built in for accurate scheduling and storing configuration information. One 4-pin header is designed to support ATX power function. All these features make ROBO-538 excellent in stand- alone applications.

The most up-to-date system architecture of ROBO-538 is based on Intel 430TX PCIset , which consists of the 82439TX System Controller (MTXC) and the 82371AB PCI ISA IDE Xcelerator (PIIX4). This equips ROBO-538 to support Pentium Processor, SDRAM, PBSRAM L2 Cache, PCI bus interface, ACPI compliant power management, USB port, SMBus communication, and Ultra DMA/33 IDE Master. The on-board super I/O chip, W83977ATF, will support PS/2 Keyboard/Mouse, two UARTs, FDC, Parallel and Infrared interface. In addition, the on-board optional IEEE-1394 interface will give user more flexibility in high-speed data transferring applications. The North Bridge 82439TX provides a completely integrated solution for the system controller and data path components in a Pentium processor system. The MTXC supports all compatible Pentium family processors since P54C. It has 64-bit Host and DRAM Bus Interface, 32-bit PCI bus interface, Second level Cache Interface with 64MB DRAM cacheability, and it will integrate 3 or 4 PCI masters which depend on number of enabling on-board PCI device to support external backplane. The South Bridge, 82371AB, provides a highly integrated multifunction PCI-to-ISA bridge solution for the best industry application. It supports 2-channel dedicated Ultra DMA/33 IDE master interfaces, full Plug-and-Play compatibility, and APIC (Advanced Programmable Interrupt Controller) interface. It also supports 2-port USB (Universal Serial Bus feature) and PCI 2.1 Compliance operation. It fully supports Operating System Directed Power Management via the Advanced Configuration and Power Interface (ACPI) specification. In addition, it also provides XD-bus via buffer logic control to support BIOS read/write access and external real- time clock (RTC) to maintain date and time of a system. The Super I/O chip W83977ATF, which integrates two high-speed serial ports, one parallel port, FIR/SIR interface, 8042 keyboard controller with PS/2 mouse ports and FDD interface. This parallel port supports one PC-compatible Standard Printer Port (SPP), Enhanced Parallel Port (EPP) and Extended Capabilities Port (ECP). The optional IEEE-1394 interface enables PC to connect to current and emerging 1394 peripherals, including DV camcorders, digital VCRs, color printers, scanners, digital still cameras, DVD players, 1394 HDDs, and more. This PCI-to-1394 Host Controller is composed of Adaptec’s AIC-5800 400Mb/s link controller chip and a IBM 21S850 400Mb/s PHY interface chip to connect up to 63 devices using easy-to- use cables and six-pin connector for true plug-and-play and “hot swapping” of peripherals. ROBO-538 User’s Manual 1-6 Introduction Two 16-bit ISA-bus interfaces, standard ISA and PC/104 bus, are applied for all of slower I/O operations. In ROBO-538, it contains Watch-dog Timer (WDT) enabled by jumper setting and triggered by software, Disk-on-Chip (DOC) for M- system Flash disk, and ISA buffer driving for special I/O applications and multi-ISA slots. Besides, an advanced feature is used on current ROBO-538 DOC architecture to expand storage size by cascading three flash disks. The detail operating relations are shown in Figure 1-1 ROBO-538 System Block Diagram.
