Functional Description
MVME7100ET Single Board Computer Installation and Use (6806800K87E) 74
The I
2
C interface is routed to the P2 connector for access to the serial EEPROM located on the
transition module. The device address for the transition module serial EEPROM is user
selectable using the configuration switches. Refer to
Chapter 5, Transition Module for
information on the switches.
For programming information, see the MVME7100ET Single Board Computer Programmer’s
Reference.
4.5 System Memory
The MC864xD includes two memory controllers. The MVME7100ET supports one bank of
memory on each controller. The MVME7100ET supports 1 GB and 2 GB DDR2 SDRAMS. This
provides memory configurations of 2 GB or 4 GB. The MVME7100ET supports memory speeds
up to DDR533.
4.6 Timers
Timing functions for the MVME7100ET are provided by four global high-resolution timers
integrated into the MC864xD plus four additional independent 32-bit timers.
The four integrated 32-bit timers are clocked by the RTC input which is driven by a 1 MHz clock.
Refer to the MC864xD reference manual, listed in
Appendix B, Related Documentation ,
Manufacturers’ Documents on page 117 for additional details and/or programming information
The clock source for the four 32-bit timers in the PLD is 25 MHz. The timer prescaler must be
configured to generate a 1 MHz timer reference. For programming information, see
MVME7100ET Single Board Computer Programmer’s Reference.
4.7 Ethernet Interfaces
The MVME7100ET provides four 10/100/1000 Mbps full-duplex Ethernet interfaces using the
MC864xD Ethernet Controllers. Two Broadcom BCM5482S PHYs are used. The Ethernet ports
on the MC864xD are configured to operate in RGMII mode. Two Gigabit Ethernet interfaces are
routed to front panel RJ-45 connectors with integrated LEDs for speed and activity indication.
The other two Gigabit Ethernet interfaces are routed to P2 for rear I/O. For programming
information, see MVME7100ET Single Board Computer Programmer’s Reference.
