xii ADSP-21262 EZ-KIT Lite Evaluation System Manual
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 (SW10)” on page 2-12. The board also has
512 KB of SRAM, which can be used at runtime.
The DAI of the processor connects to the AD1835A audio codec and the
CS8416 S/PDIF receiver. These devices facilitate creation of digital and
analog audio signal processing applications. See “Analog Audio Interface”
on page 1-8 and “Digital Audio Interface” on page 1-10 for more
information.
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.
Purpose of This Manual
