Memory Mapping
8.7.1
Internal SRAM
The SAM7S512 embeds a high-speed 64-Kbyte SRAM bank.
The SAM7S256 embeds a high-speed 64-Kbyte SRAM bank.
The SAM7S128 embeds a high-speed 32-Kbyte SRAM bank.
The SAM7S64 embeds a high-speed 16-Kbyte SRAM bank.
The SAM7S321 embeds a high-speed 8-Kbyte SRAM bank.
The SAM7S32 embeds a high-speed 8-Kbyte SRAM bank.
The SAM7S161 embeds a high-speed 4-Kbyte SRAM bank.
The SAM7S16 embeds a high-speed 4-Kbyte SRAM bank
After reset and until the Remap Command is performed, the SRAM is only accessible at address 0x0020 0000. After
Remap, the SRAM also becomes available at address 0x0.
8.7.2
Internal ROM
The SAM7S Series embeds an Internal ROM. The ROM contains the FFPI and the SAM-BA program.
The internal ROM is not mapped by default.
8.7.3
Internal Flash
The SAM7S512 features two contiguous banks (dual plane) of 256 Kbytes of Flash.
The SAM7S256 features one bank (single plane) of 256 Kbytes of Flash.
The SAM7S128 features one bank (single plane) of 128 Kbytes of Flash.
The SAM7S64 features one bank (single plane) of 64 Kbytes of Flash.
The SAM7S321/32 features one bank (single plane) of 32 Kbytes of Flash.
The SAM7S161/16 features one bank (single plane) of 16 Kbytes of Flash.
At any time, the Flash is mapped to address 0x0010 0000. It is also accessible at address 0x0 after the reset and before
the Remap Command.
