Flash Overview
The SAM3S16 product (1024-Kbyte internal Flash version) embeds a total of 128 Kbytes high-
speed SRAM.
The SRAM is accessible over System Cortex-M3 bus at address 0x2000 0000.
The SRAM is in the bit band region. The bit band alias region is mapped from 0x2200 0000 to
0x23FF FFFF.
The SAM3S16 product embeds an Internal ROM, which contains the SAM Boot Assistant (SAM-
BA), In Application Programming routines (IAP) and Fast Flash Programming Interface (FFPI).
At any time, the ROM is mapped at address 0x0080 0000.
The memory is organized in sectors. Each sector has a size of 64 KBytes. The first sector of
64 KBytes is divided into 3 smaller sectors.
The three smaller sectors are organized in 2 sectors of 8 KBytes and 1 sector of 48 KBytes.
Refer to
Figure 9-1.
Each Sector is organized in pages of 512 Bytes.
