MVME2502 Installation and Use (6806800R96E) 98
4.8 Rear UART Control
The MVME2502 utilizes the Exar ST16C554 quad UART (QUART) to provide four asynchronous
serial interface’ to the RTM. These devices feature 16 bytes of transmit and receive first-in first-
out (FIFO) with selectable receive FIFO trigger levels and data rates of up to 1.5 Mbps. Each
UART has a set of registers that provide the user with operating status and control. The QUART
are 8-bit devices connected to the processor through the local bus controller using LBC chipset
CS1, CS2, CS3 and CS4.
These four serial interfaces are routed to P2 I/O for RTM accessibility. There are total of five
serial ports available on the MVME2502 board.
4.9 PMC/XMC Sites
The MVME2502 hosts two PMC/XMC sites and accepts either a PMC or an XMC add-on card.
Only an XMC or a PMC may be populated at any given time as both occupy the same physical
space on the PCB. The MVME2502 does not support combination PMC/XMC cards. The site
provides a rear PMC I/O.
The PMC sites are fully compliant with the following:
1. VITA 39 –PCI-X for PMC.
2. VITA 35-2000 for PMC P4 to VME P2 Connection.
3. PCI Rev 2.2 for PCI Local Bus Specification.
4. PCI-X PT 2.0 for PCI-X Protocol Addendum to the PCI Local Bus Specs.
5. IEEE Standard P1386-2001 for Standard for Common Mezzanine Card Family.
6. IEEE Standard P1386.1-2001 for Standard Physical and Environmental Layer for PCI
Mezzanine Card.
7. VITA 42 for XMC.
8. VITA 42.3, PCIe for XMC.
PMC/XMC sites are keyed for 3.3V PMC signaling. The PMC and the XMC add-on cards must
have a hole in the 3.3 V PMC keying position in order to be populated on the MVME2502 board.
The XMC specification accommodates this since it is expected that carrier cards will host both
XMC and PMC capable add-on cards.
