Product Description
The ReadyBoard 620 is a mid-sized, EPIC-compatible, affordable, high quality single-board system, which
contains all the component subsystems of a PC/AT PCI motherboard plus the equivalent of several PCI
expansion boards. The ReadyBoard 620 is based on the AMD Geode™ LX 800 processor. This processor
and the matching chip set give designers a complete integration solution with a high performance embedded
processor based on the EPIC form factor.
Each ReadyBoard 620 incorporates an AMD Geode CS5536 chipset for the Graphics and Memory Hub (the
Northbridge integrated in the CPU) and I/O Hub (Southbridge) controllers. The Winbond Electronics Corp.
Super I/O controller, W83627HF, and Fintek LPC controller add I/O functions. Together, the AMD,
Winbond, and Fintek chips provide four serial ports, a floppy or EPP/ECP parallel port, four USB 2.0 ports,
PS/2 keyboard and mouse interfaces, an Ultra/DMA 33/66 IDE controller supporting two IDE drives and
one Compact Flash socket, which provides CRT and LVDS/TTL flat panel video interfaces, and an audio
AC’97 CODEC on the board. The ReadyBoard 620 also supports two 10/100BaseT Ethernet interfaces, and
up to 1 GB of non-ECC DDR RAM in a single 200-pin SODIMM socket.
The ReadyBoard 620 can be expanded through the PC/104 and PC/104-Plus expansion buses to accept
PC/104 and PC/104-Plus cards that offer compact, self-stacking, modular expandability for additional
system functions. The PCI bus operates at 33 MHz clock speed and if included as an option, the ISA bus
operates at 8 MHz clock speed. See Figure 2-1 .
Among the many enhancements provided on the ReadyBoard 620 to ensure system operation and
application versatility are a watchdog timer, serial console (remote access) support, battery-free boot,
customizable splash logo screen, on-board high-density Compact Flash socket, and ACPI support for sleep
states.
The ReadyBoard 620 is particularly well suited to embedded applications by meeting the size, power
consumption, temperature range, quality, and reliability demands of embedded system applications. It can be
stacked with ADLINK MiniModules™ or other PCI-104 compliant expansion boards, or it can be used as a
powerful computing engine. The ReadyBoard 620 only requires a 5V power supply.
