EP7309
High-Performance, Low-Power System on Chip
Internal Boot ROM
The internal 128 byte Boot ROM facilitates download of saved
code to the on-board SRAM/FLASH.
Packaging
The EP7309 is available in a 208-pin LQFP package, 256-ball
PBGA package or a 204-ball TFBGA package.
Pin Multiplexing
The following table shows the pin multiplexing of the DAI,
SSI2 and the CODEC. The selection between SSI2 and the
CODEC is controlled by the state of the SERSEL bit in
SYSCON2. The choice between the SSI2, CODEC, and the
DAI is controlled by the DAISEL bit in SYSCON3 (see the
EP7309 User’s Manual for more information).
