Board Description and Memory Maps

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.

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 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.
