In this case, the MVME3100 supports:
Note
On PMC site 1, the user I/O – J14 signals will only support the low-current, high-speed
signals and are not to be used for any current bearing power supply usage. The maximum
current rating of each pin/signal is 100 mA.
current rating of each pin/signal is 100 mA.
USB
The USB 2.0 host controller provides USB ports with integrated transceivers for connectivity
with any USB-compliant device or hub. USB channel 1 is routed to a single USB connector
located at the front panel. DC power to the front panel USB port is supplied via a USB power
switch, which provides soft-start, current limiting, over-current detection, and power enable for
port 1. Refer to the µPD720101 USB 2.0 Host Controller Datasheet listed in

PMC Expansion
The MVM3E3100 provides additional PMC module capability through the use of a connector on
bus C that is compatible with the PMCspan boards. Up to four additional PMC modules may be
added by using existing PMCspan boards. Refer to the PMCspan PMC Adapter Carrier Board
Installation and Use manual listed in

General-Purpose Timers
There are a total of eight independent, 32-bit timers. Four timers are integrated into the
MPC8540 and four timers are in the PLD. The four MPC8540 timers are clocked by the RTC
input, which is driven by a 1 MHz clock. The clock source for the four timers in the PLD is 25
MHz. Refer to the MPC8540 Reference Manual listed in

Real-time Clock Battery
There is an on-board Renata SMT battery holder on the MVME3100. This SMTU2430-1 holder
allows for quick and easy replacement of a 3V button cell lithium battery (CR2430), which
provides back-up power to the on-board DS1375 RTC. A battery switching circuit provides
automatic switching between the 3.3V and battery voltages. The battery provides backup power
to the RTC for a minimum of one year at nominal temperature.
