Overview

Intel Celeron processors (P.P.G.A.) 370

The Intel Celeron processors provide power to handle the internet, educational
programs, interactive 3D games, and productivity applications. The Intel Celeron
processors at 700, 667, 633, 600, 566, 533, 500, 466 and 433 MHz include inte­grated L2 cache 128Kbyte. The core for the 700, 667, 633, 600, 566, 533, 500,
466 and 433 MHz processors have 19M transistors due to the addition of the inte­grated L2 cache 128Kbyte. All the Intel Celeron processors are available in the
plastic pin grid array (P.P.G.A.) form factor. The P.P.G.A. form factor is compat­ible with the 370 pin socket. All the Intel Celeron processors are available in the
plastic pin grid array (PPGA) package. The PPGA package is compatible with the
370 pin socket and provides more flexibility to design low cost systems by en­abling lower profile and smaller systems and providing the potential for reducing
costs of processor retention and cooling solutions. Like the Intel Celeron proces­sors that utilize S.E.P.P., the Intel Celeron processors that use P.P.G.A., feature a
P6-microarchitecture-based core processor on a single-sided substrate without
BSRAM componentry.

The Intel Celeron processor at 700, 667, 633, 600, 566, 533, 500, 466 and 433
MHz. Includes Intel MMX[tm] media enhancement technology. Offers Dynamic
Execution technology.
Includes a 32Kbyte (16Kbyte/16Kbyte) non-blocking, level-one cache that provides
fast access to heavily used data. Intel Celeron processors at 700, 667, 633, 600,
566, 533, 500, 466 and 433 MHz include integrated L2 cache 128Kbyte. All the
Intel Celeron processor utilize the Intel P6 microarchitectures multi-transaction
system bus at 66MHz. The 700, 667, 633, 600, 566, 533, 500, 466 and 433 MHz
processors utilize the Intel P6 microarchitectures multi-transaction system bus
with the addition of the L2 cache interface. The combination of the L2 cache bus
and the processor-to-main-memory system bus increases bandwidth and perfor­mance over single-bus processors.

IntroductionEP-3S1A

Page 1-3

Intel MMX technology includes new instructions and data types that allow
applications to achieve a new level of performance. Intels MMX technology is
designed as a set of basic, general-purpose integer instructions that are easily
applied to the needs of a wide diversity of multimedia and communications
applications. The highlights of the technology are:

* Single Instruction, Multiple Data (SIMD) technique

* 57 new instructions

* Eight 64-bit wide MMX technology registers

* Four new data types

Intel Coppermine processors (FC-PGA) 370

These Coppermine-128K and Coppermine-256K processor is the next addition to the
P6 micro architecture product family. The FC-PGA package is a new addition to the
Intel IA-32 processor line and hereafter will be referred to as the Coppermine FC­PGA processor, or simply The processor. The package utilizes the same 370-pin
zero insertion force socket (PGA370) used by the Intel Celeron processor. Thermal
solutions are attached directly to the back of the processor core package without the
use of a thermal plate or heat spreader.

The Coppermine processor, like the Intel Celeron, Intel Pentium II and Pentium III in
the P6 family processor, implement a Dynamic Execution micro architecture --- a unique
combination of multiple branch prediction, data flow analysis, and speculative
execution. This enable these processors to deliver higher performance than the Intel
Pentium processor, while maintaining binary compatibility with all previous Intel Ar­chitecture processors. The processor also executes Intel MMX technology instruc­tions for enhanced media and communication performance just as its predecessor the
Intel Pentium III processor. Additionally the Coppermine FC-PGA processor executes
streaming SIMD (Single-Instruction Multiple Data) Extensions for enhanced floating
point and 3-D application performance. The concept of processor identification, via
CPUID, is extended in the processor family with the addition of a processor serial
number. The processor utilizes multiple low-power states such as AutoHALT, Stop­Grant, Sleep and Deep Sleep to conserve power during idle times.

Introduction EP-3S1A

Page 1-4

The processor includes an integrated on-die, 128KB or 256KB, 8-way set associa­tive level-two (L2) cache with a separated 16KB level one (L1) instruction cache
and 16KB level one (L1) data cache. These cache arrays run at the full speed of the
processor core. As with the Intel Pentium III processor, the Coppermine FC-PGA
processor has a dedicated L2 cache bus, thus maintaining the dual independent bus
architecture to deliver high bus bandwidth and performance. Memory is cacheable
for 4GB/64GB of addressable memory space, allowing significant headroom for
desktop system.

Intel(R) 815 Series chipset features

The Intel(R) 815 series chipset that SDRAM interface supports 100MHz and
133MHz operation, the Intel(R) 815 series chipset has re-engineered the Value
PC, providing next generation features and great graphics performance.

The 82815 series Graphics Memory Controller Hub (GMCH) features : Intel(R)
graphics technology and software drivers, using Direct AGP (integrated AGP) to
create vivid 2D and 3D effects and images. The 82815 series chip feature
integrated Hardware Motion Compensation to improve soft DVD video quality.

The Inte(R) 82815 series chipset use Intel(R) Dynamic Video Memory Technol­ogy (D.V.M.T.) is an architecture that offers breakthrough performance for the
(motherboard) PC through efficient memory utilization and Direct AGP. The system
OS uses the Intel software drivers and intelligent memory arbiter to support richer
graphics applications.

The Intel(R) 82815 series provides an AGP universal connector to support the
AGP 2.0 including 4X AGP data transfers.

The 82801AA I/O Controller Hub (ICH1) employs the Intel(R) Accelerated Hub
Architecture to make a direct connection from the graphics and memory to the
integrated AC97 controller, the IDE controllers (ATA/66 or ATA/33), dual USB
ports, and PCI add-in cards.

The Accelerated Hub Architecture provides twice the bandwidth of the PCI bus at
266 MB per second. This allows a wider flow of rich information from the I/O

IntroductionEP-3S1A

controller to the memory controller, with optimized arbitration rules allowing
more functions to run concurrently, enabling more life-like audio and video.

The Integrated Audio-Codec 97 controller enables software audio by using the
processor to run sound. By reusing existing system resources, this feature adds
flexibility, improves sound and modem quality.

The 82802 Firmware Hub (FWH, 4MB) stores system BIOS and video BIOS,
eliminating a redundant nonvolatile memory component. In addition, the 82802
contains a hardware Random Number Generator (RNG). The Intel(R) RNG
provides truly random numbers to enable fundamental security building blocks
supporting stronger encryption, digital signing, and security protocols for the
future application program .

Introduction EP-3S1A

EP-3S1A Form-Factor

The EP-3S1A is designed with ATX form factor - the new industry standard of
chassis. The ATX form factor is essentially a Baby-AT baseboard rotated 90
degrees within the chassis enclosure and a new mounting configuration for the
power supply. With these changes the processor is relocated away from the
expansion slots, allowing them all to hold full length add-in cards. ATX defines a
double height aperture to the rear of the chassis which can be used to host a wide
range of onboard I/O. Only the size and position of this aperture is defined,
allowing PC manufacturers to add new I/O features (e.g.; TV input, TV output,
modem, LAN, etc.) to systems. This will help systems integrators differentiate
their products in the marketplace, and better meet your needs.

 Smaller size promotes a smaller system size.

 I/O shield does not need to be retooled in an ATX 2.01 or later. Mainboard

could be used in an ATX 2.01-compliant.

 A smaller power supply cam be used. High integration on mainboard reduces

the system costs.

The EP-3S1A has a single 20-pin connector for ATX power supplies. For ATX
power supplies that support the Remote On/Off feature, this should be connected
to the systems front panel for system Power On/Off button. The systems power
On/Off button should be a momentary button that is normally open.
The EP-3S1A has been designed with Soft Off" functions. You can turn Off the
system from one of two sources: The first is the front panel Power On/Off the
button, and the other is the "Soft Off" function (coming from the EP-3S1As
onboard circuit controller) that can be controlled by the operating system such as
Windows 95/98. System will be turn off automatically after you click the START
button and Resume the Shutdown selection.

System Memory Configuration

Memory Layout

The EP-3S1A supports (3) 168-pin DIMMs (Dual In-line Memory Module). The
DIMMs is for SDRAM (Synchronized DRAM).

 FSB 66/100MHz for 100MHz SDRAM interface only, FSB 133MHz for

100/133MHz SDRAM interface.
 32MB to 256MB using 64MB technology (512MB using 128MB

technology), maximum 512MB on 3 DIMM sockets.
 No Registered SDRAM Memory Modules Support.
 Double Side Unbuffered Memory Module without ECC supports.
 We recommend using at least 125MHz (-8ns) SDRAM at the 100MHz (or

higher) FSB as timing becomes more critical at these higher speeds.
 DIMM SDRAM may be 100MHz (-10ns) or 133MHz (-7.5ns) bus speed.

Figure 6 and Table 1 show several possible memory configurations.

* SDRAM only supports 32, 64, 128, 256MB DIMM modules.

* We recommend to use PC100 Memory Module for bus speed (FSB) between

66MHz/100MHz and PC133 Memory for bus speed (FSB) between 100MHz/

133MHz.

* Using non-compliant memory with higher bus speed (over clocking) may

severely compromise the integrity of the system.
