7521 N/B MAINTENANCE N/B MAINTENANCE 7521 1.1 HARDWARE ENGINEERING SPECIFICATION 1.1.1 General Description This document describes the engineering specification for 7521 portable notebook computer system. 1.1.2 System Overview The 7521 model motherboard will accept Intel Pentium III and Celeron processor with FC-PGA packaged. Which will supports the different levels of Pentium III CPU with FC-PGA package. Those are Pentium III 600/650/700/750/800 MHz, and Celeron 600/633/667/700/733 MHz . This system is based on PCI architecture and is fully compatible with IBM PC/AT specification, which have standard hardware peripheral interface and support Intel Pentium III with FC-PGA package. The power management complies with Advanced Configuration and Power Interface (ACPI) 1.0. It also provides easy configuration through CMOS setup, which is built in system BIOS software and can be pop-up by pressing F2 at system start up or warm reset. System also provides icon LEDs to display system status, such as AC Power indicator, FDD, HDD, NUM LOCK, CAP LOCK, SCROLL LOCK, SUSPEND MODE and battery present, capacity & charging status. It also equipped with LAN, FIR, USB port, 3D stereo audio functions. The memory subsystem supports 64MB on board SDRAM, one 144pin DIMM socket for upgrading up to 192 MB of DRAM using SDRAM DIMM module. The SiS 630 integrates the north bridge chip, super south bridge and the real 128-bit 3D graphics accelerator all into one single chip. It provides 10/100M Fast Ethernet, 3D Positional Audio, Advance H/W DVD playback and 2D/3D graphics engine. 2

7521 N/B MAINTENANCE N/B MAINTENANCE 7521 The TI 1225 cardbus controller supports PCMCIA and CARDBUS. The National Semiconductor PC97338 Super I/O controller integrates the standard PC I/O functions: floppy interface, two FIFO serial ports, one EPP/ECP capable parallel port, and support for an IrDA 1.1, 1.0 and sharp ASK compatible infrared interface. To provide for the increasing number of multimedia applications, an CODEC CS4299 is integrated onto the motherboard which support 16-bit stereo, Sound Blaster Pro, Windows Sound System compatibility, and full-duplex capabilities to meet the demands of interactive multimedia applications A full set of software drivers and utilities are available to allow advanced operating systems such as Windows 95 or Windows 98 to take full advantage of the hardware capabilities. Features such as bus mastering IDE, Windows 95- ready Plug and Play, Advanced Power Management (APM) with application restart, software-controlled power shutdown.. 1.2 Hardware System 1.2.1 System parts Central Processing Unite : using Intel Pentium Ⅲ or Celeron microprocessors in FC-PGA packaged.

7521 N/B MAINTENANCE N/B MAINTENANCE 7521 1.2.2 CPU MODULE Intel Pentium Ⅲ/ Celeron Processors with 370 pins PGA package. Pentium Ⅲ 600/650/700/750/800 MHz, FC-PGA package at FSB 100MHz. Celeron 600/ 633/ 667/ 700/ 733 MHz, FC-PGA package. 1.2.3 Synthesizer System frequency synthesizer : ICS9248-102 - Maximized EMI suppression using Integrate Circuit System’s spread spectrum technology. - Three copies of CPU output, output to output skew between them within 175ps and seven copies of PCI output, output to output skew between them 500ps, fourteen copies of SDRAM output, output to output skew between them within 250ps. - One 48MHz outout for USB and selectable 24/48 MHz output ( pin25 ). - Two buffer copies of 14.318MHz input reference signal. - Supports up to 166MHz CPU or SDRAM operation. - Supports two SDRAM DIMMS. - Ideal for high performance Desktop/ Notebook designed using SIS630 chip set. - I²C serial configuration interface. 1.2.4 SiS630 Slot 1/Socket 370 2D/3D Ultra-AGP™ Single Chipset The single chipset SiS630, provide a high performance/ low cost Desktop soloution for the Intel Slot 1 and socket 370 series CPUs based system by integrated a high performance North Bridge, advanced hardware 2D/3D GUI engine and Super-South bridge. In addition. SiS630 provides system-on-chip solution that complies with Easy PC Initiative which supports instantly Available OnNow PC technology, USB, Legacy Removal and Slotless Design and FlexATX form factor. 4

7521 N/B MAINTENANCE N/B MAINTENANCE 7521 By integrating the UltraAGP™ technology and advanced 128-bit graphic display interface, SiS630 delivers AGP 4x-like performance and up to 2 GB/s memory bandwidth. Furthermore, SiS630 provides powerful hardware decoding DVD accelerator to improve the DVD playback performance. In addition to providing the standard interface for CRT monitors, SiS630 also provides the Digital Flat Panel Port (DFP) for a standard interface between a personal computer and a digital flat panel monitor. To extend functionality and flexibility, SiS also provides the ?Video Bridge?(SiS301) to support the NTSC/PAL Video Output, Digital LCD Monitor and Secondary CRT Monitor, which reduces the external Panel Link transmitter and TV-Out encoder for cost effected solution. SiS630 also adopts Share System Memory Architecture which can flexibly utilize the frame buffer size up to 64MB. The “Super-South Bridge” in SiS630 integrates peripheral controllers / accelerators / interfaces. SiS630 provides a total communication solution including 10/100Mb Fast Ethernet for Office requirement and 1Mb HomePNA for Home Networking. SiS630 offers AC’97 compliant interface that comprises digital audio engine with 3D-hardware accelerator, on- chip sample rate converter, and professional wavetable along with separate modem DMA controller. SiS630 also provides interface to Low Pin Count (LPC) operating at 33 MHz clock which is the same as PCI clock on the host, and dual USB host controller with five USB ports that deliver better connectivity and 2 x 12Mb bandwidth. The built-in fast PCI IDE controller supports the ATA PIO/DMA, and the Ultra DMA33/66 function that supports the data transfer rate up to 66 MB/s. It provides the separate data path for two IDE channels that can eminently improve the performance under the multi-tasking environment.
