Application Environments
This section provides an overview of the application environments such as the STMicroelectronics and
Embest ARM9
processors, for which the 78Q8430 provides a seamless interface.
shows a
simple application diagram for a design using the GBI based 10/100-Mbps Ethernet Controller. By
providing a direct connection to the GBI bus, applications requiring Ethernet network access can be
realized with a high degree of integration. The figure shows the processor and the Ethernet controller
with connected address and data buses. This connection can be either on the motherboard, or via an
expansion module. The GBI Controller controls the address and data and the system control signals.

Figure 6: GBI Bus Block Diagram
Figure 6 shows the components that are likely to be used with the 10/100-Mbps Ethernet Controller. The
integrated PHY is designed to directly connect to an integrated 1:1 transformer and RJ-45 connector,
thereby providing a minimum parts solution.
1.5
Supply Voltages
The 78Q8430 requires a single 3.3 V (+/-5%) supply voltage. No external components are required to
generate on-chip bias voltages and currents. High accuracy is maintained through a closed-loop trimmed
biasing network. On-chip power converters generate 1.8 V power for core digital logic and memory
blocks. The voltage regulator is not affected by the power-down mode.
1.6
Power Management
The 78Q8430 supports both normal and power-saving modes. When the GBI bus is active, it can be in
normal mode or Power Management low-power modes.
