3301770
This chapter provides a functional description of the 3301770 embedded board designed
for the integration into a compact size chassis. This chapter includes information about
main processors, interface connectors, implementation options, and signal description.
2.1 CPU, Memory, and VIA Chipsets
CPU
The 3301770 comes with a soldered low voltage VIA MARK processor. The VIA MARK CoreFusion
design integrates high-performance ProSavage4 3D/2D graphics controller, LCD and Flat Panel
display interfaces, with the burst and concurrent operation pipelining capability for fast data
distribution among CPU, DRAM, and PCI buses. CPU and the Northbridge functionalities are
provided in a single processor package. The CPU is accompanied by the VT82C686B
Southbridge featuring PC98/PC99 with integrated UltraDMA-66/100 IDE, USB, and a complete
power management feature set. The VT82C686B also provides hardware monitoring, super I/O
functions (floppy disk drive and serial/parallel ports. The AC’97 capabilities are provided by a
Realtek ALC655 chip supporting digital audio output.
The CPU is passively cooled over a heatsink made in aluminum alloy and is ideal for small form
factor computing applications with its low power consumption and minimum heat dissipation.
Shown below are some of the key features of the VIA MARK CoreFusion processor:
