TM
F28335 Memory
The eZdsp includes the following on-chip memory:
In addition 128K x 16 off-chip SRAM is provided. The processor on the eZdsp can be
configured for boot-loader mode or non-boot-loader mode.
The eZdsp can load ram for debug or FLASH ROM can be loaded and run. For larger
software projects it is suggested to do a initial debug with on eZdsp F28335 module
which supports a total RAM environment. With careful attention to the I/O mapping in
the software the application code can easily be ported to the F28335.
