1. INTRODUCTION
Welcome to the AR-B1665 Single Embedded Board Computer in EBX form factor board. AR-B1665 provides a
flexible system that allows users to choose the performance of system as their wish. AR-B1665 supports Socket
370 Pentium III (Coppermine and Tualatin), Intel Celeron, Via C3 processors with speed up to 1.26G with FSB
100/133 /66 MHz. AR-B1665 is equipped with high performance VIA ® advanced chipset CLE266 version CD
(North Bridge VT8623-CE plus South Bridge VT8235-CD). This product is designed for the system manufacturers,
integrators, or VARs that want to provide all the performance, reliability, and quality at a reasonable price.
AR-B1665 provides one 184 pin DIMM socket that supports up to 1 GB DDR266/DDR200 (PC2100/PC1600)
Double Data Rate(DDR) SDRAM. The DDR interface allows zero wait state bursting between the DRAM and the
data buffer at 133/100 MHz.
AR-B1665 also provides on board VGA(CRT and 24 bit LCD),one LAN that support 10/100M Base-Tx, AC97 Codec
