21 / 98 page  21 AT32UC3A 9. Memories 9.1 Embedded Memories • Internal High-Speed Flash – 512 KBytes (AT32UC3A0512, AT32UC3A1512) – 256 KBytes (AT32UC3A0256, AT32UC3A1256) – 128 KBytes (AT32UC3A1128, AT32UC3A2128) - 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 • Internal High-Speed SRAM, Single-cycle access at full speed – 64 KBytes (AT32UC3A0512, AT32UC3A0256, AT32UC3A1512, AT32UC3A1256) – 32KBytes (AT32UC3A1128) 9.2 Physical Memory Map 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: Table 9-1.
