Introduction
WAFER-6820 is designed for limited space applications with only the
size of a 3½" hard drive. Itsupports the full functions of an AT-compatible
industrial computer on a single board. The WAFER-6820 is equipped with a
low-power consumption and high performance Transmeta TM3200
processor on board. It also contains an SDRAM SODIMM socket that can
support up to 128MB memory.
The WAFER-6820 provides an Ethernet interface, audio interface,
Compact Flash Type II, EIDE interface, one parallel port, one serial port
RS-232, one serial port RS-232/422/485 with auto-direction, and a mini-DIN
PS/2 keyboard/mouse interface. The built-in SVGA/LCD display controller
supports both the CRT and LCD display simultaneously. It offers the
resolutions of LCD screen up to 1024 x 768 and CRT resolutions up to 1280
x 1024 @ 16 colors. The display type is configured by software utility. The
Flash ROM contains both the system BIOS and the VGA BIOS.
Reprogramming the Flash ROM could do the modification, in case of
necessary.
The RS485 has an outstanding characteristic of intelligent directing
control, which eliminates the extra control signal like RTS. With this feature
you can develop your program as you are using a normal RS232 without
special control routine. This is especially important in WINDOWS
programming which do not allow the program to catch the control pin at

2
your wish.
Finally, one PC/104 connector is included for the future application you
will need.
Notes:
The Transmeta Crusoe™ TM3200 will occupy 16MB memory space to
save its CMS code temporally. So we must indicate the memory type for
Tramsmeta Crusoe™ TM3200. Because this point, we will attaché one
128MB SDRAM module that we approved in the package.
1.1 Specifications:
The WAFER-6820 TM3200 with VGA Computer provides the
following specification:
•CPU: Low power Transmeta Crusoe ™TM3200 400 MHz
•Bus: ISA bus
•DMA channels: 7
•Interrupt levels: 15
•Chipset: TM3200 + VIA VT82C686A
•PCI VGA: C&T 69000 with 2MB SDRAM built-in Chipset
Resolution: 1280x1024, 256 color, 60Hz
1024x768, 64K color, 85Hz
800x600,full color, 85Hz
•Ethernet Interface:
Chipset: Realtek 8139C 100Base-TX Fast Ethernet Controller
Ethernet Interface: Onboard 100Base-TX RJ-45+LED Connector
•H/W status Monitoring: VT82C686A H/W status monitoring
IC supports power supply voltages and temperatures monitoring
•Real-Time Clock/Calendar: built-in VT82C686A chipset, backup by
industrial Li-battery, 3V/300mAH. .
•DRAM: supports to 128MB,SDRAM.

•Ultra DMA/33 IDE Interface: supports up to two PCI Enhance IDE hard
drives. The Ultra DMA/33 IDE can handle data transfer up to 33MB/s.
The best of all is that it is compatible with existing ATA-2 IDE
specifications. So there is no need to do any change for customer’s
current accessory.
•Floppy disk drive interface: two 2.88 MB, 1.44MB, 1.2MB, 720KB, or
360KB floppy disk drives.
•Two high-speed Serial ports: NS16C550 compatible UARTs, and one
RS422/485 port with auto-direction function.
•
Bi-directional Parallel Port: IEEE 1284 compatible
•IrDA port: Support serial Infrared (SIR).
•USB port: Support two USB ports for future expansion, USB 1.1
compliant.
•Watchdog timer
•CompactFlash disk: The CompactFlash Storage Card also runs in
True IDE Mode that is compatible with an IDE disk drive. It can be used
with a passive adapter in a Type II socket.
•Keyboard connector
•Mouse: PS/2 Mouse Port on-board.
•Power Consumption: +5V @ 1.8A
(Transmeta TM3200, 128MB SDRAM)
•Operating Temperature: 0°~ 60°C (CPU needs heat sink)

Installation
This chapter describes how to install the WAFER-6820. At first, the
layout of WAFER-6820 is shown, and the unpacking information
that you should be careful is described. The jumpers and switches
setting for the WAFER-6820's configuration, such as watchdog
timer, are also included.
