Function
Celeron 433-MHz processor with 100 MHz FSB
Uses Accelerated Hub Architecture to make direct connection
from graphics and memory to the integrated AC97 controller,
IDE controller, and dual USB ports.
Supports PCI bus interface, integrated IDE controller, USB,
AC'97 Link for audio and telephone Codecs, interrupt controller,
timers, 3.3V operation, power management logic, enhanced
DMA controller, real-time clock, SM bus, and Firmware Hub.
Packaged in a 241-pin Ball Grid Array.
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®
RNG provides truly random numbers to enable fundamental
security building blocks supporting stronger encryption, digital
signing, and security protocols.
Features Intel Platform Compatibility, Firmware Hub Hardware
Interface Mode, configurable interfaces, flash memory for non-
volatile storage, and address/address multiplexed interface
mode.
Packaged in a 32-pin PLCC.
Uses Intel graphics technology, software drivers, and Direct
AGP (integrated AGP) to create vivid 2D and 3D effects and
images. Features integrated Hardware Motion Compensation to
improve video quality and a digital video out port that enables
connection to space-saving digital flat panel displays.
Features processor and host bus optimized for the Celeron
processor, integrated DRAM controller, integrated graphics
controller, 3D graphics visual enhancements, 3D graphics
texturing enhancements, digital video output, integrated 24-bit
230 MHz RAMDAC, 2D graphics, arithmetic stretch blitter
video, integrated graphics memory controller, display cache
interface, arbitration scheme and concurrency, data buffering,
power management functions, and support for I/O bridge.
Packaged in a 421-pin Ball Grid Array
