Functional Description
The MVME2300 series is a family of single-slot VME processor modules.
It consists of the MPC603/604 processor, the Raven PCI Bridge and
Interrupt Controller, the Falcon ECC Memory Controller chip set, 3MB or
5MB of Flash memory, 16MB to 128MB of ECC-protected DRAM, and a
rich set of I/O features.
I/O peripheral devices on the PCI bus are: Ethernet chip, Universe
VMEbus interface ASIC, and two PMC slots. Functions provided from the
ISA bus are: one asynchronous serial port, a real-time clock,
counters/timers, and a software-readable header.
VMEbus Interface
MVME2300 series boards interface to the VMEbus via the P1 and P2
backplane connectors. MVME2300SC boards use the three-row 96-pin
connectors specified in the original VMEbus standard; non-SCbus
MVME2300 boards use the 5-row 160-pin connectors specified in the
VME64 Extension standard.
Both types of boards draw +5V, +12V, and –12V power from the VMEbus
backplane through these two connectors. 3.3V and 2.5V supplies are
regulated onboard from the +5 power.
Front Panel
Front panel connectors on the non-SCbus MVME2300 series boards
include an RJ45 connector for the Ethernet 10BaseT/100BaseTX
interface, and a second RJ45 connector for the asynchronous serial debug
port.
Front panel connectors on the MVME2300SC include an RJ45 connector
for the Ethernet 10BaseT/100BaseTX interface, and a 9-pin DB9
connector for the asynchronous serial debug port.
