The EPC
®
-6315 PrPMC (Processor PCI Mezzanine Card) uses the RadiSys 82600
integrated chipset to bring an Intel Architecture processor into ultra-dense form
factors. With the ability to accept a type I Compact Flash device, the EPC-6315 can
be a completely self-standing processor in any application.
The EPC-6315 includes an 800MHz Pentium III processor with up to 512MB of
on-board SDRAM. The EPC-6315 also features ECC protection of memory with
single-error correction and double-error detection capability. Performance is
maximized with the standard 133MHz PSB and 133MHz memory bus. For
maximum flexibility, the EPC-6315 leverages the dual mode PCI-to-PCI bridge
capability of the RadiSys 82600 to automatically configure the bridge based on the
strapping of the slot on the baseboard. This capability allows the EPC-6315 to
become a Monarch PrPMC, and provide PCI bus enumeration and service
interrupts on the PCI bus or a non-Monarch PrPMC and function as a PCI-based
auxiliary processor.
The Jn1 and Jn2 connectors provide a 32-bit 33/66MHz interface to the PCI bus on
the baseboard as well as providing power and ground. The optional Jn4 connector
provides a full set of I/O, which includes EIDE, COM, and keyboard/mouse
interfaces. The front panel provides 10/100BASE-T Ethernet connector and
Compact Flash socket.
