1. Introduction
Thanks for choosing 3307940 PENTIUM-M Single Board
Computer. The 3307940 board is a PCISA form factor
board equipped with high performance processor and
multi-mode I/O. It is designed for system manufacturers,
integrators, or VARs that want to provide all the
performance, reliability, and quality at a reasonable
price.
In addition, the 3307940 has a build-in AGP4X
VGA(Intel 852GM)with 3D graphics capabilities to
provide up to 2048x1536x16 color resolution. The
onboard VGA shares 8MB system DDR-SDRAM .
An advanced high performance super AT I/O chip –
Winbond W83627HF is used in the 3307940 board.
Both on-chip UARTs are compatible with the NS16C550.
The parallel port and IDE interface are compatible with
IBM PC/AT architecture.
The 3307940 has a built-in(ICH4) 10/100 Fast
Ethernet LAN port. It is fully integrated 10BASE-
T/100BASE-TX LAN solution with high performance
networking functions and low power features.
The 3307940 uses the advanced Intel 852GM chipset
which is 100% software compatible chipset with PCI 2.1
standard.
