System Architecture
This section describes the processor’s configuration on the EZ-KIT Mini
board (
Figure 2-1 ).
This EZ-KIT Mini is designed to demonstrate the ADSP-BF706 proces-
sor’s capabilities. The ADSP-BF706 EZ-KIT Mini has a 25 MHz input
clock and runs at 400 MHz internally.
USB circuitry and a micro USB AB connector are provided for connecting
to the EZ-KIT Mini as a host or a device. The frequency for the USB cir-
cuit is generated by an external 24 MHz crystal.
User I/O to the processor is provided in the form of one user push button
and one LED. See
ADSP-BF706 EZ-KIT Mini Schematic for more
information.
