1 PMCspan Introduction
The PMCspan is a PMC carrier module that provides PCI expansion capability. PMCspans
have the following features:
❏ Compatible with the MVME51005E and MVME55006E processor modules (hereafter
referred to as the MVME5100 and MVME5500 processor modules)
❏ Support for two single-width PMC module or one double-width PMC module
❏ +5V bus signaling voltage
❏ Support for both PMC Bus and VMEbus connectors with the following features:
– Two sets of three EIA E700 AAAB connectors for 32-bit PMC interface to secondary
PCI bus and user specific I/O
– P1 connector for power and BGNT and IACK daisy chaining
– 5-row P2 connector for power and PMC I/O
❏ PCI6150 PCI-to-PCI Bridge Interface device, with the following features:
– PCI Revision 2.1 compliant
– 32-bit primary bus interface
– 32-bit secondary bus interface
– Delayed transactions for all PCI configuration, I/O, and memory read commands,
allowing up to three transactions simultaneously in each direction
– Buffering (data and address) for posted memory write commands in each direction,
allowing up to five posted write transactions simultaneously in each direction
– Read data buffering in each direction
– Concurrent primary and secondary bus operation to isolate traffic
– Enhanced address decoding
– PCI transaction forwarding
