®
C3 Processor CPU with Multimedia
& LAN Ethernet Embedded Little Board, which comes equipped with Low
power VIA
®
C3 Processor CPU with the Intel advanced chipset 815E. This
product is designed for the system manufacturers, integrators, or VARs that
want to build a low power consumption system.
NOVA-7820 provides on-chip VGA which provides up to 1600 x 1200
resolution. LCD which provides up to 1024 x 768 resolution.
An advanced high performance super I/O chip – W83627 and NS87366 is
used in the NOVA-7820 board. Which provide four UARTs are compatible
with the NS16C550. The parallel port and FDD interface are compatible with
IBM PC/AT architecture's.
The NOVA-7820 has one Fast Ethernet Multifunction PCI Controller as a LAN
controller, Which are fully integrated 10BASE-T/100BASE-TX LAN solution
with high performance networking functions and low power features.
This board has a built-in Compact Flash Disk Socket, CardBus, FireWire for
embedded applications.
