1.1 Introduction
EM-660 offers two computing power options: VIA C3 533MHz and C3 800MHz. VIA C3 533MHz is
designed especially for fan-less requirement to enable better MTBF. As an x86 architecture, the platform
supports prevail operating systems such as Windows 95/98SE/XP/2000/NT and Linux. Your previous
investment on these operating systems is, thus, protected in the following 4 years. With 192KB internal
L1/L2 cache integrated in the CPU, your applications are able to benefit more execution speed from this
mechanism.
VIA Twister-T chipset is the mid-end position of VIA chipsets. It supports 2D/3D Video Accelerator by
integrating S3 Savage4. It also supports 36-bit TFT LCD and 2 channel (2 x 18-bit) LVDS. Using LCD
50-pin box header, EM-660 is able to compatible with the most coming bigger size industrial and
commercial LCDs. By enabling VRAM, the system can further cut its cost and while maintains its speed.
EM-660 uses SODIMM to limit its board height and supports PC 133/PC 100.
There are two storage options in EM-660 design. One is EIDE, and the other is CF II. EIDE supports two
IDE devices. EM-660 offers 2 IDE box header options to fulfill flexible hard disk placement in system
design. 40-pin box header focuses on 3.5” hard disk, 44-pin box header mainly couples itself with 2.5”
hard disk. Regarding to CF II socket, system can further cut its whole size when using popular large
volume CF II form factor SSD.
EM-660 embodies the following I/O: 1 x LAN, 1 x FDD, 4 x COM, 1 x LPT, Keyboard & Mouse, 2 x USB, 1
x IrDA and 4 x DIO. Expansion slots include PC/104 and PCI. Power supply complies with AT and ATX.
Watchdog timer is 16-level.
As an industrial PC embedded card, EM-660’s operating temperature is ranging from 0°C to 60°C. All
these numerous features provide an ideal price/performance solution for commercial and industrial
applications where stability and reliability are essential.
