The exact power requirement of the EBX-11 depends on several factors, including memory
configuration, CPU speed, peripheral connections, type and number of expansion modules and
attached devices. For example, PS/2 keyboards typically draw their power directly from the
EBX-11, and driving long RS-232 lines at high speed can increase power demand.

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.
Nominal battery voltage is 3.0V. If the voltage drops below 2.7V, contact the factory for a
replacement (part number HB3/0-1). The life expectancy under normal use is approximately 10
years.
CPU
The Geode LX 800 microcontroller has a 32-bit, low-voltage AMD x86 microprocessor at its
core. The maximum clock rate is 500 MHz actual, with 800 MHz (Celeron equivalent)
performance. The LX 800 features 64 kb of L1 cache, 128 kb of L2 cache, DDR SDRAM
support, and an integrated display controller. The CPU operates without a heat sink and has a
typical power consumption of 1.6W.

LEARING
A jumper may be installed into V3[2-3] to erase the contents of the CMOS RAM and the Real-
Time Clock. When clearing CMOS RAM: 1) Power off the EBX-11. 2) Remove the jumper from
V3[1-2], install it on V3[2-3] and leave it for four seconds. 3) Move the jumper to back to
V3[1-2]. 4) Power on the EBX-11.
