CPU Subsystem
The CPU subsystem uses a high performance 64-bit RISC processor with the following memories:
• DDR3 DRAM
• Application FLASH (SD-memory card)
• Boot FLASH
The application software is stored in FLASH memory. Thus, it is possible to update the software
on the
fi
eld when new software feature packs become available. Similarly, the card and interface
parameters are stored in FLASH, so those are restored after reset.
PLD
Various system control functions are embedded in SUP PLD.
I2C
I2C bus and switches are used for accessing devices such as EEPROMs, A/D converters and
temperature sensors.
