Power Specifications

Table 2-5 provides the power requirements for the 300 MHz and 800 MHz versions of the CoreModule 435.

Operating configurations:

• In-rush operating configuration includes CRT video, 256MB DDR2 RAM, and power.

• Idle operating configuration includes the in-rush configuration as well as on-board Compact Flash with

64MB card, and one keyboard.

• BIT (Burn-In-Test) operating configuration includes idle configuration as well as two serial port loop-

backs, two Ethernet connections, and four USB Compact Flash readers with 64MB Compact Flash.

Environmental Specifications

Table 2-6 provides the operating and storage condition ranges required for this module.

Thermal/Cooling Requirements

The CPU is the primary source of heat on the board. The 800 MHz version of the CoreModule 435 CPU is

designed to operate at its maximum speed and requires a heatsink (provided). The 300 MHz version of the

CoreModule 435 CPU also is designed to operate at its maximum speed but does not require a heatsink. See

note on page 15 for height of the heatsink.
