CP390
1. Introduction
1.1 Overview
PMC modules are renowned for their flexibility and versatility of use. They afford the
user wide ranging system independent solutions by means of easily interchanged or
upgraded mezzanine add-on modules. The PEP CP390 has been designed to maxi-
mize the advantages provided by PMC modules in a 3U environment. Flexibility, versa-
tility, convenience and ease of use have been keynotes throughout the design process.
The result is a board which, although essentially a carrier for PMC modules, also
includes a wide range of important features such as a PCI-PCI bridge and (optionally
available) the ability to hotswap. Use of the hotswap version means, of course, that all
PMC modules employed on the board are effectively hotswapable.
The CP390 is a 3U non-intelligent, active CPCI carrier board with one PMC slot.
Some of the Outstanding Features of the CP390:
• active carrier with PCI-to-PCI bridge: the primary and secondary PCI busses are
capable of being operated independently of one another
• 32 Bit / 33MHz PCI Bus on the CPCI and on the PMC side
• it supports the Interrupts INTA, INTB, INTC and INTD
• software transparent: the non-hotswap version does not require a software driver.
• it supports all the signals of the PCI Bus on its connectors Jn1 (CON2),
Jn2 (CON3)
• The connectors which connect the mezzanine board with the carrier include all the
signals of a 33MHz, 32-bit, multi-master PCI bus, the power rails for 5V, 3.3V,
V(I/O) and other specialised signals for Board Detection.
• A PCI-to-PCI bridge provides for coupling of the PMC side to the CompactPCI
side, so that two independent PCI busses exist. The PCI-to-PCI bridge is the
INTEL 21150. It is software transparent and consequently a software driver is not
required to manage data transfer between the PMC module and the CPCI bus.
• The CP390 has been designed to function with all PEP CompactPCI backplanes.
Features of the PEP Modular Computers' PMC modules
PEP Modular Computers' PMC modules are operable in both CompactPCI and VME
systems. They offer all the key benefits of PC I/O technology, namely:
• low cost solutions
• high performance
• a processor independent local I/O bus
• a broad range of I/O peripheral devices
PEP Modular Computers' PMC modules may be installed on a variety of different carrier
boards, including:
• CompactPCI 3U/6U: CPU CP600, CP602, CP610, CP611, CP612
• CompactPCI PMC carrier boards such as the CP390 and CP690
Customers who additionally require the functionality of the CP390 in the 6U Form
Factor are referred to PEP's new double-height PMC Module carrier board, the
CP690, which holds two PMC modules.
