1 Motherboard Description 1.1 Overview ® The TE430VX design accepts Pentium processors operating at 75 MHz, 90 MHz, 100 MHz, 120 MHz, 133 MHz, 150 MHz, 166 MHz, and 200MHz. There is an option of having 256 KB of Pipeline Burst SRAM soldered onto the motherboard, or a Card Edge Low Profile (CELP) connector for cache expandability. The memory subsystem is designed to support up to 128 MB of EDO DRAM, or up to 64 MB of a new memory architecture called SDRAM, in standard 168-pin ® DIMM sockets.

TE430VX Motherboard Technical Product Specification 1.4 Microprocessor The motherboard is designed to operate with 3.3 volt Pentium Processors running at 75, 90, 100, 120, 133, 150, 166, and 200MHz. An onboard linear voltage regulator circuit provides the required 3.3 volts from the 5.0 volt tap of the power supply. An on-board jumper enables use of VRE specified processors. The Pentium processor maintains full backward compatibility with 8086, 80286, i386 and Intel486 processors. It suppo

Motherboard Description 1.5.1.2 SDRAM Synchronous Dynamic Random Access Memory, (SDRAM) is designed to improve main memory performance. SDRAM is synchronous to the memory clock unlike standard Fast Page DRAM, or EDO DRAM. All the timing is dependent on the number of memory clock cycles. This makes the timing design simpler and makes a faster memory speed easier to achieve. Discrete SDRAM components must meet the 66 MHz PC SDRAM Specification version 1.0 to function correctly. 1.5.2 Second Le

1.6.2 82430VX Data Path (TDX) Two 82430VX TDX data path components provide a 64-bit microprocessor to memory path. The TDX components are controlled by the TVX. They each add one load to the PCI bus and perform all of the required byte and word swapping. The TDX devices come in a 208 pin QFP package. 1.6.3 PCI ISA/IDE Xcelerator (PIIX3) The PIIX3 provides the interface between the PCI and ISA buses and integrates a dual channel fast IDE interface capable of supporting up to 4 devices. The PI

Motherboard Description 1.7 Ultra I/O Interface Controller (SMC FDC37C93FR) 1.7.1 Floppy controller The SMC FDC37C93FR is software compatible with the DP8473 and 82077 floppy disk controllers. The floppy interface can be configured for 360 KB or 1.2 MB 5¼" media or for 720 KB, 1.2 MB, 1.44 MB, or 2.88 MB 3½" media in the BIOS setup. By default, the Floppy A interface is configured for 1.44 MB and Floppy B is disabled. Another setup option prevents the user from being able to write to floppy.

TE430VX Motherboard Technical Product Specification The audio subsystem requires up to two DMA channels (to support full duplex operation) and one interrupt. When the Vibra 16C is programmed for full duplex operation, two DMA channels are assigned: one of the channels will be a 16-bit channel and the other will be 8 bits. The system can be configured to use either DMA channels 1 or 3 (8 bit channels) and DMA channels 5 or 7 (16 bit channels). The interrupt can be mapped to IRQ 5, 7, 9, or 10.
