7.1. Memory
configuration
The
ePanel-C3
uses only DDR-RAM (SO-DIMMs). One socket is available for 3.3 Volt (power level) unbuffered
Synchronous Double Data Rate (DDR), Small Outline Dual In-Line Memory Module (DDR SDRAM SO-DIMMs).
Specification of the PC2100 Module is using 133 MHz clock (266 MT/s data rate) of either 64 Mb, 128 MB, 256
MB, 512 MB, 1 GB.
7.2. Watchdog
TBD ( Not supported yet ).
7.3. Compact Flash Socket (True IDE compatible)
A compact flash socket for commercial CF cards (Type
Ι
+
ΙΙ
) is already integrated on the module. This socket
can serve as boot drive and is not hot-pluggable.
7.4. Ethernet 10BASE-T/100BASE-TX LAN
The Ethernet controller is a physical Layer device for 10Base-t and 100Base-TX using category 5
Unshielded and 1 Type shielded cables. Autonegotiation for :
-
Dual Speed - 10 / 100Mbps
-
Half and Full Duplex
Meets IEEE 802.3 10 Base-T and 100 Base-TX Standards
7.5. Smart battery charger
The Smart Battery Charger is a charging circuit that provides the Smart Battery with charging current and
charging voltage to match the Smart Battery's requested requirements. This allows the battery to control its
own charge cycle, thus providing a chemistry independent interface to the battery system. Optionally, the Smart
Battery Charger may not allow the Smart Battery to supply power to the rest of the system when the Smart
Battery is fully charged and the system is connected to AC power thus prolonging the life of the battery. The
Smart Battery Charger will also receive critical events from the Smart Battery when it detects a problem. These
include alarms for charging conditions or temperature conditions which exceed the limits set within the particular
Smart Battery. Charging of the battery is independent of state of the CPU, thus allowing the battery to be
charged even if the CPU is powered down. Minimum/Maximum charging voltage is 8V/18.4V and
minimum/maximum charging current 7mA/3A. Supply voltage has to be 12% higher as peak charging voltage.
7.6. Video Input / Output
The SAA7118E is a combination of a four-channel analog preprocessing circuit including source selection,
anti-aliasing filter and ADC, an automatic clamp and gain control, a Clock Generation Circuit (CGC), a digital
multistandard decoder containing two-dimensional chrominance/luminance separation by an adaptive comb
filter and a high performance scaler, including variable horizontal and vertical up and downscaling and a
brightness, contrast and saturation control circuit. The target application for the SAA7118E is to capture and scale
video images, to be provided as digital video stream through the image port of the VGA controller for overlay
purposes. Up to 16 CVBS, 8 S-VIDEO or 4 Component inputs are supported. Software control is integrated in the
system BIOS and sample applications are available.
7.7. Wide range DC power supply
The power supply of the board has an input range from 8V to 28V DC. The power supply switches over to
battery supply, if the main power supply voltage falls below 8V. All internal supply voltages are generated on
board.
