Chapter 2 Product Overview
CoreModule 420 Reference Manual 15
NOTE The CoreModule 420 is in violation of the PC/104 height limitations in two
places on the bottom of the board. The voltage regulator (U19) exceeds the
allowed height limitation by 0.085 inches and the compact flash socket (J12)
exceeds the height limitation by 0.2 inches. See Figure 2-6.
Power Specifications
Table 2-6 provides the power requirements.
Table 2-6. Power Supply Requirements
Parameter Characteristics
Input Type Regulated DC voltages
In-rush* Current +5 VDC +/- 5% @ 13.72 Amps
BIT** Current
(Typical) +5 VDC +/- 5% @ 1.51 Amps (7.56W)
Notes: *In-rush measured with video, 64 MB memory (fixed), and power connected. Typically, in-rush
current reflects the short duration current spike associated with charging large on-board bulk capacitance
during power supply start up. However, the in-rush current value is the result of placing a switch on the
DC output of a fully 'ramped' power supply to give a worst-case current value, which is much higher
than the standard method. This in-rush value should be regarded as a maximum design guideline, not a
requisite or typical value.
**The average BIT (burn in test) current is conducted with 64 MB memory (fixed), a floppy disk drive
(FDD), a IDE hard disk drive (HDD), keyboard, mouse, serial loopbacks (4), externally connected USB
HDD (1), and active Ethernet channel (1) in a Windows
® 2000 operating system (OS) environment.
Environmental Specifications
Table 2-7 provides the operating and storage condition ranges required for this module.

Parameter Conditions
Temperature
Operating -20
° to +70° C (-4° to 158° F)
Extended (Optional) –40° to +85° C (–40
° F to +185° F)
Storage –55° to +85° C (–67
° F to +185° F)

Thermal/Cooling Requirements
The CPU, Super I/O, and voltage regulator are the sources of heat on the board. The CoreModule 420 is
designed to operate at its maximum CPU speed of 133 MHz and requires a heatsink (provided).
