Single-Chip North Bridge for Socket-A (Socket-462) Based Athlon CPUs with 200 / 266 MHz Front Side Bus for Desktop PC Systems with AGP 4x and PCI plus Advanced Memory Controller supporting PC133 / PC100 SDRAM and VCM

OVERVIEW
The KT133A chipset (VT8363A north bridge and VT82C686A south bridge) is a high performance, cost-effective and energy efficient system controller for the implementation of AGP / PCI / ISA desktop personal computer systems based on 64-bit Socket A (AMD Athlon) processors. The VT8363A supports FSB speeds of 200 and 266 MHz.
The KT133A chip set consists of the VT8363A system controller (552 pin BGA) and the VT82C686A PCI to ISA bridge (352 pin BGA). The system controller provides superior performance between the CPU, DRAM, AGP bus, and PCI bus with pipelined, burst, and concurrent operation.
