PCA-6743 User Manual 2
1.1 Introduction
PCA-6743 is the ultimate cost-effective solution for limited space applications. It
offers all the functions of an AT-compatible industrial computer on a single board. The
new CPU module supports DM&P Vortex86DX SOC (system on chip) which supports
ISA interfaces. The Vortex86DX is a high performance and fully static 32-bit X86 pro-
cessor compatible with Windows and DOS support. It also integrates 32KB write
through 4-way L1 cache, 4-way 256KB L2 cache, PCI rev. 2.1 32-bit bus interface at
33 MHz, DDR2, ROM controller, IPC (Internal Peripheral Controllers with DMA and
interrupt timer/counter included), Fast Ethernet, FIFO UART, USB2.0 Host and IDE
controller within a single 581-pin BGA package to form a system-on-a-chip (SOC).
PCA-6743's on-board features include a 10/100 Ethernet interface, Compact Flash
socket (Type I/II) shared with Primary IDE, Enhanced IDE interface, one parallel port,
up to four serial ports, one FFD port, and a PS/2 keyboard/ mouse interface. An
SVGA/LCD display controller (LCD and CRT displays) allows LCD screen resolutions
up to 1024 x768 @ 18/24 bit LVDS/TTL (Optional) and CRT resolutions up to 1024 x
768 @ 24 bit true color. If you need any additional functions, PCA-6743 also supports
a PC/104 connector for future upgrades.
PCA-6743 is ideal for data-acquisition, environment monitoring system, Intelligent
Vehicle management device, and factory automation that requires basic X86 comput-
ing power for various low-power.
