Functional Description
MVME4100ET Single Board Computer Installation and Use (6806800K76F) 72
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 MVME4100ET Single Board Computer Programmer’s
Reference.
4.5 System Memory
The MVME4100ET includes one SO-CDIMM socket. The SO-CDIMM socket supports 2 GByte
DDR2 SDRAM module. The MVME4100ET supports memory speeds up to DDR533.
4.6 Timers
Timing functions for the MVME4100ET are provided by four global high-resolution timers
integrated into the MPC8548E plus four additional independent 32-bit timers in a PLD.
The four integrated 32-bit timers are clocked by the RTC input which is driven by a 1 MHz clock.
Refer to the MPC8548E reference manual, listed in
Appendix B, Related Documentation ,
Manufacturers’ Documents on page 115 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
MVME4100ET Single Board Computer Programmer’s Reference.
4.7 Ethernet Interfaces
The MVME4100ET provides four 10/100/1000 Mbps full-duplex Ethernet interfaces using the
MPC8548E Ethernet Controllers. Two Broadcom BCM5482S PHYs are used. The Ethernet ports
on the MPC8548E 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 MVME4100ET Single Board Computer Programmer’s Reference.
