The WinSystems PCM-586-133-16M is a PC/104-compliant Single Board Computer engineered for embedded systems demanding PC compatibility in a compact, rugged form factor. Built on the AMD 5×86 processor running at 133 MHz with integrated 80-bit floating-point unit, it delivers the computational performance required for demanding embedded applications while maintaining full compatibility with standard PC operating systems including DOS, Windows CE, and Windows 95/98/NT.
Technical Specifications
Processor & Memory
• AMD 5×86 CPU at 133 MHz with 16 KB onboard cache
• Floating-point unit: 80-bit architecture
• Surface-mounted EDO DRAM: up to 32 MB factory-populated (4 MB, 16 MB, or 32 MB options available)
• DRAM soldered directly to board for improved shock and vibration resistance
Storage & Boot
• 128 KB Flash PEROM with industry-standard AWARD or Phoenix BIOS
• 32-pin DIP socket for bootable storage modules up to 1 MB (PE-ROM, SRAM, EPROM)
• Native support for M-Systems DiskOnChip 2000 and DiskOnChip 2800 modules (2 MB to 72 MB)
• Onboard IDE and floppy disk controllers
• USSD.SYS device driver provided for MS-DOS and ROM-DOS environments
I/O Interfaces
• Two RS-232 COM channels (COM1, COM2) with integrated transceivers
• Optional RS-422/485 capability via CK-75176 chip kit replacement
• RS-422/485 supports balanced multi-drop network configurations
• Keyboard and mouse controllers integrated on core logic chipset
• Parallel printer port onboard
Expansion & Integration
• 16-bit PC/104 bus connector for peripheral expansion
• ACC Micro 2089 core logic chipset integrating DRAM controller, bus interface, AT peripheral functions, and I/O controllers on single chip
• Compatible with wide range of PC/104 modules: VGA controllers, sound modules, SCSI controllers, analog I/O
– Key Features
• Full PC/AT hardware and software compatibility
• BIOS shadowed into DRAM for accelerated POST execution
• Single-chip core logic reduces component count and improves system reliability
• Factory-soldered DRAM eliminates socket reliability concerns in harsh environments
– Compatibility & Integration
The board integrates with standard PC operating systems and DOS derivatives. Device driver support and bootable disk utilities (MK-DISK) enable rapid deployment in DOS-based embedded systems. PC/104 expansion capability permits integration of specialized I/O, graphics, and communication modules without redesign of the core platform.
