Motorola CPCI-6115 manual Processor PMC Support, PMC Slots, PrPMC Signal Support

PMC Slots Functional Description

from the PMC J14 connector to the CompactPCI J3 I/O connector while the PMC J24 connector signals are routed to the CompactPCI J5 I/O connector. Both PMC I/O connectors are routed to their respective CompactPCI I/O connector following the PIM differential signalling recommendations. The CPCI-6115 front panel allows for front I/O through the PMC faceplate.

PMC slot 1 supports:

zMezzanine Type: PMC = PCI Mezzanine Card

zMezzanine Size: S1B = Single width and standard depth (75mm x 150mm) with front panel

zPMC Connectors: J11, J12, J13, and J14

zSignaling Voltage: +5 V

zSupported modes: 32-bit, 33 MHz PCI

zI/O: front panel and CompactPCI J3 rear panel

PMC slot 2 supports:

zMezzanine Type: PMC = PCI Mezzanine Card

zMezzanine Size: S1B = Single width and standard depth (75mm x 150mm) with front panel

zPMC Connectors: J21, J22, J23, and J24

zSignaling Voltage: Vio = +3.3 V (+5 V tolerant) or +5 V, selected by keying pin

zSupported modes: 32/64-bit 33/66 MHz PCI or 66/133 MHz PCI-X

zI/O: front panel and CompactPCI J5 rear panel

In addition, the PMC connectors are located such that a double width PMC may be installed in place of two single PMCs.

In this case, the CPCI-6115 supports:

zMezzanine Type: PMC = Mezzanine Card

zMezzanine Size: double width and standard depth (150mm x 150mm) with front panel

zPMC Connectors: J11, J12, J13, J14, J21, J22, J23, J24

zSignaling Voltage: +5 V

zSupported modes: 32-bit 33 MHz PCI

zI/O: front panel and CompactPCI J3 rear panel

The following special-function processor PMC pins, as defined by the draft Processor PMC Standard VITA 32-199x, are implemented on the CPCI-6115 as described in the following sections.

PrPMC Signal	Support
PRESENT#	The PRESENT# signal from each PMC slot is used to detect the presence of a
	PMC. The state of this bit is readable in the board Presence Detect Register.
