The EZ-KIT Lite board has a total of 1 MB of parallel flash memory and
2 Mbit of SPI flash memory. The flash memories can store user-specific
boot code, allowing the board to run as a stand-alone unit. For more
information, see “External Memory” on page 1-7 and “Boot Mode and
Clock Ratio Select Switch (SW2)” on page 2-8. The board also has
512 KB of SRAM and 16 MB of SDRAM, which can be used at runtime.
The DAI port of the processor connects to the AD1835A audio codec, an
external phase lock loop (PLL), and the SPDIF interface. The DAI inter-
face facilitates development of digital and analog audio signal-processing
applications. See “Analog Audio” on page 1-9 and “SPDIF Coax Connec-
tors (P8 and P9)” on page 2-23 for more information.
The DPI port of the processor connects to the UART interface and the
SPI interface. The UART interface can connect to a standard RS-232 con-
nection, while the SPI connects to the 2 Mbit of serial flash memory.
Additionally, the EZ-KIT Lite board provides access to all of the proces-
sor’s peripheral ports. Access is provided in the form of a three-connector
expansion interface. See “Expansion Interface” on page 2-7 for details.
