2. Introducing the EDB9302A Engineering Development Board
This document will describe the features and basic operation of the EDB9302A board developed by
Cirrus Logic. Detailed information regarding the operation and programming of the EP9302 device are
covered by the EP9302 datasheet and User's Guide on the Cirrus Logic web site.
The EDB9302A is a convenient and easy-to-operate evaluation platform. It has been designed to provide
the majority of the EP9302 functions on a small 6" x 4" base board. These features include:
• EP9302 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
• Two UARTs
• 10/100 Ethernet Interface
• JTAG
• Consumer IR (CIR)
• Expansion Connectors
• 5-channel ADC
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.
