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 in boot. Note that AVR32 UC CPU uses unsegmented
translation, as described in the AVR32 Architecture Manual. The 32-bit physical address space
is mapped as follows:
Internal High-Speed Flash
Internal High-Speed SRAM, Single-cycle access at full speed
– 512 KBytes (AT32UC3A0512, AT32UC3A1512)
– 256 KBytes (AT32UC3A0256, AT32UC3A1256)
– 128 KBytes (AT32UC3A1128, AT32UC3A2128)
– 64 KBytes (AT32UC3A0512, AT32UC3A0256, AT32UC3A1512, AT32UC3A1256)
– 32KBytes (AT32UC3A1128)
- 0 Wait State Access at up to 33 MHz in Worst Case Conditions
- 1 Wait State Access at up to 66 MHz in Worst Case Conditions
- Pipelined Flash Architecture, allowing burst reads from sequential Flash locations, hiding
penalty of 1 wait state access
- Pipelined Flash Architecture typically reduces the cycle penalty of 1 wait state operation
to only 15% compared to 0 wait state operation
- 100 000 Write Cycles, 15-year Data Retention Capability
- 4 ms Page Programming Time, 8 ms Chip Erase Time
- Sector Lock Capabilities, Bootloader Protection, Security Bit
- 32 Fuses, Erased During Chip Erase
- User Page For Data To Be Preserved During Chip Erase
