2. Introducing the EDB9315A Engineering Development Board
This document will describe the features and basic operation of the EDB9315A board developed by
Cirrus Logic. Detailed information regarding the operation and programming of the EP9315 device are
covered by the EP9315 datasheet and User's Guide on the Cirrus Logic web site.
The EDB9315A is a convenient and easy-to-operate evaluation platform. It has been designed to provide
the majority of the EP9315 functions on a small 6" x 4" base board. These features include:
• EP9315 Processor Running at 200MHz
• 64MByte SDRAM
• 16MByte NOR Flash Memory
• Two USB 2.0 Full-speed Host Ports
• USB 2.0 High-speed Device Interface
• Audio Out
• Audio In
• Three UARTs
• 10/100 Ethernet Interface
• VGA
• IDE
• JTAG
• Consumer IR (CIR)
• Expansion Connectors
• LCD Interface with Touch Screen Support
Note: The EDB9315A kit does not include a LCD screen. The LCD interface is pin-compatible with
previous Cirrus Logic development boards.
Not all features of the EP9315 are on the base board. Two high-density connectors have been provided
to allow for daughter card expansion. The full memory bus is connected to one of the connectors and
any peripherals not on the development board are attached to the other connector. In addition, some
features such as Ethernet MII interface have been brought out to the peripheral connector as well.
