The TPS65930 communicates with the CPU through the I2C protocol. It
supplies 1.2V and 1.8V to keep CPU working properly. Additionally, the
TPS65930 features Audio in, Audio out, OTG PHY, Keyboard, ADC and
GPIO functions.
2.2.2 H9DA4GH2GJAMCR Memory
The H9DA4GH2GJAMCR is a two-in-one memory which combines 512MB of
NAND Flash and 256MB of SDRAM DDR. The NAND Flash is accessed
through the GPMC bus, while the SDRAM is accessed through the
Controller (SDRC).
2.2.3 DM9000 Ethernet Controller
The DM9000 is a fully integrated fast Ethernet controller with a general
processor interface, a 10/100M PHY and 4K DWORD SRAM. It supports
3.3V with a 5V tolerance.
The SBC8140 uses the 10/100M self-adaptive network interface of the
DM8000 which is a standard RJ45 interface with connection and data
transfer indicators. The 10/100M Ethernet module integrated in the
DM9000 is compliant with the IEEE 802.3 standard.
The SBC8140 can be either connected to a hub with a straight-through
network cable, or to a PC with a cross-over network cable.
2.2.4 FE1.1 USB Hub
FE1.1 is a USB 2.0 high-speed 4-port hub solution. It uses the USB3320 to
provide 4 extended USB interfaces with support for high-speed (480MHz),
full-speed (2MHz) and low-speed (1.5MHz) modes.
2.2.5 TFP410 Flat Panel Display IC
The TFP410 is a Texas Instruments PanelBus flat panel display product,
part of a comprehensive family of end-to-end DVI 1.0-compliant solutions,
targeted at the PC and consumer electronics industry.
The TFP410 provides a universal interface to allow glue-less connection to
most commonly available graphics controllers. Some of the advantages of
this universal interface include selectable bus widths, adjustable signal
levels, and differential and single-ended clocking. The adjustable 1.1V to
1.8V digital interface provides a low-EMI, high-speed bus that connects
