User's Manual
System Memory
2.5
The MSC CXC-PV525 CPU module provides two sockets for memory modules which have
to meet the following demands:
 204pin unbuffered DDR3 SO-DIMM
 1.5V supply voltage
 DDR3-800 / PC3-6400 or faster
 Maximal module height: 30mm
 SPD (Serial Presence Detect) EEPROM
Power Supply
2.6

+12V primary power supply input

+5V standby
Option, is not required for module operation.
If not present, customer has to make sure that the supply voltages which are
generated on the carrier board are switched off during suspend states, so that no
current from the carrier board’s signal lines can flow to the CPU board.

3.3V RTC power supply
Option, is not required for module operation.
BIOS SETUP data is stored in a non volatile backup memory device (EEPROM),
therefore configuration data will not get lost during power off (except for time and date
information)

Current Dissipation
All measurements were made by plugging a MSC CXC-PV525 module onto a MSC CXEVA2 Baseboard with a multimeter connected to the +12V Line. The module was equipped
with two 1GByte memory modules.
Three tests were performed:
1. Booting Dos 6.22 from an USB stick.
2. Booting Microsoft Windows XP Professional SP3 from an SATA harddrive to the
desktop.
3. Booting Microsoft Windows XP Professional SP3 from an SATA harddrive and using
BurnIn Test V4.0 to achieve 100% CPU load.
