Technical Manual
ePanel-C3
Version 1.04
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 of either 64Mb, 128MB, 256MB,
512MB, 1GB.
7.2. Compact Flash Socket (True IDE compatible)
Ι+ΙΙ
A compact flash socket for commercial CF cards (Type
) is already integrated on the module. This socket
can serve as boot drive and is not hot-pluggable.
7.3. 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 Type 1 Shielded cables. Autonegotiation for:
Dual Speed: 10 / 100Mbps
Half and Full Duplex
Meets IEEE 802.3 10Base-T and 100Base-TX Standards.
7.4. 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.
7.5. 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 (Composite), 8 S-Video or 4 Component (RGB) inputs are supported.
Software control is integrated in the system BIOS and sample applications are available.
