Flash Memory Parameters
•
•
The system bus is implemented as a bus matrix. All system bus addresses are fixed, and they
are never remapped in any way, not even during boot. Note that AVR32 UC CPU uses unseg-
mented translation, as described in the AVR32 Architecture Manual. The 32-bit physical address
space is mapped as follows:

– 32Kbytes
• 0 wait state access at up to 25MHz in worst case conditions
• 1 wait state access at up to 50MHz in worst case conditions
• Pipelined flash architecture, allowing burst reads from sequential flash locations, hiding
• Pipelined flash architecture typically reduces the cycle penalty of 1 wait state operation
• 100 000 write cycles, 15-year data retention capability
• Sector lock capabilities, bootloader protection, security bit
• 32 fuses, erased during chip erase
• User page for data to be preserved during chip erase
penalty of 1 wait state access
to only 8% compared to 0 wait state operation
