2. Introducing the EDB9307A Engineering Development Board

This document will describe the features and basic operation of the EDB9307A board developed by

Cirrus Logic. Detailed information regarding the operation and programming of the EP9307 device are

covered by the EP9307 datasheet and User's Guide on the Cirrus Logic web site.

The EDB9307A is a convenient and easy-to-operate evaluation platform. It has been designed to provide

the majority of the EP9307 functions on a small 6" x 4" base board. These features include:

• EP9307 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

•JTAG

• Consumer IR (CIR)

• Expansion Connectors

• LCD Interface with Touch Screen Support

Note: The EDB9307A kit does not include a LCD screen. The LCD interface is pin-compatible with

previous Cirrus Logic development boards.

Not all features of the EP9307 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.
