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
