Feature summary
The EPC-3305 CPU board is a Pentium
†
III-based, PC-compatible, single slot
CompactPCI computer designed for use with CompactPCI bus.
The EPC-3305 is an EMC2-based design that accepts a Pentium III based EMC2.
To achieve this, the CPU board uses the Intel 21554 PCI-PCI bridge (Drawbridge),
a non-transparent PCI-PCI bridge that allows the CPU board to interface to an
intelligent host. The Intel Pentium III chipset (443BX and PIIX4E) provides the
local PCI (bus-0) interface. Four integrated PCI peripherals provide cPCI, dual
Ethernet, EIDE, and ISA interfaces. Of these, the PIIX4E provides the EIDE, and
ISA interfaces.
The EPC-3305 CPU board includes:
• Intel EMC2: Pentium III with 100 MHz. Front Side Bus
• Intel North Bridge 443BX: Host Bus to PCI bridge Memory bus controller
• 64-bit CompactPCI interface on J1/J2 using Intel 21554 non-transparent PCI
bridge with I/O slot compatibility
• Hot Swappable
• Two PMC sites with RTM Interface on Jn4
• On-board SDRAM operating at 100MHz; up to 512MB of ECC SDRAM on
board. Build-time options allow for configurations of: 128M, 256M or 512M
• Optional Rear Transition Module provides:
• COM 1 RS232 (DB9)
• COM 1 RS232 (10 pin header)
• One USB connector
• Connectors for mouse and keyboard
• A header for secondary
• Two Ethernet ports that support
EIDE 10/100BASE-T
• PIM S17E
• Intel South Bridge PIIX4E:
• PCI to ISA bridge
• Battery-backed RTC
• Two independent EIDE channels
• 4MByte Boot Block Flash memory, partitioned into eight 512Mbyte banks
• Onboard headers for:
• Floppy
• ITP
• Mouse/Keyboard
• RadiSys manufacturing Header
• Port 80 Header
• CPLD JTAG
