LITHIUM BATTERY Warning! To prevent shorting, premature failure or damage to the lithium battery, do not place the board on a conductive surface such as metal, black conductive foam or the outside surface of a metalized ESD protective pouch. The lithium battery may explode if mistreated. Do not recharge, disassemble or dispose of in fire. Dispose of used batteries promptly. Normal battery voltage should be at least 3.0V. If the voltage drops below 3.0V, contact the factory for a replacement (part number T-HB3/5-3). The life expectancy under normal use is approximately 10 years. Note: The EPIC-2 is designed to boot even with a dead or removed battery. See page 22 for further information.
COMPATIBLE MEMORY MODULES
The EPIC-2 accepts one 200-pin SODIMM memory module with the following characteristics: • Size Up to 512 MB • Voltage 2.5V • Error Detection Non-Parity • Type Unbuffered PC2100 (DDR266) or PC2700 (DDR333) CPU The Geode GX 500 microcontroller has a 32-bit, low-voltage AMD x86 microprocessor at its core. The maximum clock rate is 366 MHz actual, with 500 MHz performance. Extended temperature (“e”) versions of the EPIC-2 are clocked down to 333 MHz actual, 450 MHz performance. It features 32 kb of level 1 cache, DDR SDRAM support, and an integrated display controller. The CPU has a typical power consumption of 1.1W.
CLEARING CMOS RAM
A jumper may be installed into V1[2-3] to erase the contents of the CMOS RAM and the RealTime Clock. When clearing CMOS RAM: 1) Power off the EPIC-2. 2) Install the jumper on V1[2-3] and leave it for four seconds. 3) Move the jumper to back to V1[1-2]. 4) Power on the EPIC-2.The EPIC-2 permits users to modify the CMOS Setup defaults. This allows the system to boot up with user-defined settings from cleared or corrupted CMOS RAM, battery failure or battery-less operation. All CMOS setup defaults can be changed, except the time and date. The CMOS Setup defaults can be updated with the BIOS Upgrade Utility. (See product support page for details) Warning! If the CMOS Setup defaults settings make the system unbootable and prevent the user from entering CMOS Setup, the EPIC-2 needs to be serviced by the factory.
