System Architecture
This section describes the processor’s configuration on the EZ-KIT Lite
board (
Figure 2-1 ).
The EZ-KIT Lite is designed to demonstrate the ADSP-BF592 Blackfin
processor capabilities. The processor has an I/O voltage of 3.3V. The core
voltage of the processor is controlled by an Analog Devices ADP1715 low
dropout regulator (LDO) and an Analog Devices AD5258 digipot, which
is configurable over the 2-wire interface (TWI) signals. Refer to the
Figure 2-1. EZ-KIT Lite Block Diagram
