KX133 AMD ATHLON™ NORTH BRIDGE

Single-Chip North Bridge

for Slot-A Based Athlon CPUs

with 200 MHz Front Side Bus

for Desktop PC Systems

with AGP 4x and PCI

plus Advanced ECC Memory Controller

supporting PC133 / PC100 SDRAM and VCM

• High Performance and High Integration Athlon AGP 4x / PC133 Chipset with Advanced System

Power Management

− KX133 Chipset: VT8371 system controller and VT82C686A PCI to ISA bridge

− Single chip Athlon system controller with 64-bit Slot-A / Athlon CPU, 64-bit system memory, 32-bit PCI and 32-bit

AGP interfaces

− PCI-to-ISA bridge chip includes UltraDMA-33/66 EIDE, 4 USB Ports, Integrated Super-I/O, AC97 / MC97 link (for

Audio and Modem support), Hardware Monitoring, Power Management, and Keyboard / PS2-Mouse Interfaces plus

RTC / CMOS on chip

− Supports separately powered 3.3V (5V tolerant) interface to system memory, AGP, and PCI bus

− Modular power management and clock control for advanced system power management

• High Performance Athlon CPU Interface

− Supports Slot-A (AMD Athlon) processors

− HSTL-like 1.5V high-speed transceiver logic signal levels

− Support independent address, data, and snoop interfaces

− 100 MHz DDR (Double Data Rate) transfer on Athlon CPU address and data buses

− Built-in PLL (Phase Lock Loop) circuitry for optimal skew control within and between clocking regions

− Four-entry command queue to accommodate maximum CPU throughput

− Four-entry probe queue to stores probes from the system to the processor

− Twenty four-entry processor system data and control queue to store system data control commands in two separate

read and write buffers for data movement in and out of processor interface

− Supports WC (Write Combining) cycles

− Sleep mode support

− System management interrupt, memory remap and STPCLK mechanism
