High-integration PC/104 Single Board System with Onboard Ethernet and Video
The CoreModule™ 420 PC/104 Single Board System is a state-of-the-art, high-integration x86-based computer on a
single PC/104 board with extensive I/O for industrial applications. Based on the STMicroelectronics™ 133MHz STPC®
Atlas processor, the CoreModule 420 provides complete embedded PC functionality, including Ethernet and video
interfaces, normally found on larger boards. Standard features include processor, 64MB soldered SDRAM memory,
four RS232 serial ports (one with RS485 capability), EPP /ECP parallel port, USB port, floppy port and DMA EIDE disk
interface, 10/100BaseT Ethernet and high-resolution 2D video with CRT and TFT flat panel interfaces. The
CoreModule 420 offers two types of solid-state disk interfaces, with a bytewide socket supporting DiskOnChip® 2000
devices as well as a Type II Socket supporting CompactFlash devices. This extraordinary level of integration allows a
single module to serve a wide range of embedded applications.
In spite of its high level of integration, the CoreModule 420 remains fully compliant with the PC/104
Specification. It replaces earlier CPU modules that required two or even three PC/104 cards to provide
equivalent functionality, reducing both package size and the cost of CPU electronics by as much as 50%.
Like all Ampro CoreModule boards, development with the CoreModule 420 is supported by QuickStart
kits, complete Development Systems (including power supply and disk drives) and Board Support
Packages (BSPs) for popular operating systems. Finally, the CoreModule 420 meets the high quality
standards and ruggedized environment, including extended temperature specifications, that you would
expect from the inventor of the PC/104 and EBX standards.
