Description : AMD-762™ System Controller

Features
The AMD Athlon™ processor POWERs the next generation in computing platforms, delivering the ultimate performance for cutting-edge applications and an unprecedented computing experience.

The AMD-760MPX™ and AMD-760MP™ chipsets are highly integrated system logic solutions that deliver enhanced performance for the AMD Athlon™ processor and other AMD Athlon processor system bus-compatible processors. The AMD-760MPX chipset consists of the AMD-762™ system Controller in a 949-pin Ceramic Column Grid Array (CCGA) package and the AMD-768™ peripheral bus Controller. The AMD-760MP chipset consists of the AMD-762 system Controller in a CCGA package and the AMD-766™ peripheral bus Controller.

The AMD-762 system Controller features the AMD Athlon system bus, system memory Controller, Accelerated Graphics Port (AGP) Controller, and Peripheral Component Interconnect (PCI) bus Controller. Figure 1 on page 5 shows a block diagram for the AMD-760MPX chipset. Figure 2 on page 6 shows a block diagram for the AMD-760MP chipset.

The AMD-762 system Controller is designed with the following
features:
■ Two AMD Athlon processor system buses support the high-speed, split-transaction AMD Athlon system bus interface. These buses are designed to operate at 100/200-MHz or 133/266-MHz double-data rate.
■ A 66/33-MHz 64/32-bit PCI 2.2-compliant bus interface supports up to seven bus masters plus the AMD-766 peripheral bus Controller at 33 MHz or up to two bus masters plus the AMD-768 peripheral bus Controller at 66 MHz.
■ The 66-MHz AGP 2.0-compliant interface supports 1x, 2x, and 4x data transfer mode.
■ High-speed memory—The AMD-762 system Controller is designed to support DDR SDRAM DIMMs, operating at either 100/200-MHz or 133/266-MHz double-data rate. Note that the DDR interface speed is always locked to the frontside bus speed.
