Flash Overview
The SAM4S16 device (1024 Kbytes) embeds a total of 128-Kbytes high-speed SRAM.
The SAM4S8 device (512 Kbytes) embeds a total of 128-Kbytes high-speed SRAM.
The SRAM is accessible over System Cortex-M4 bus at address 0x2000 0000.
The SRAM is in the bit band region. The bit band alias region is from 0x2200 0000 to
0x23FF FFFF.
The SAM4S embeds an Internal ROM, which contains the SAM Boot Assistant (SAM-BA
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 to consist of 2 sectors of 8 KBytes and 1 sector of 48
KBytes. Refer to
Figure 8-1.
Each Sector is organized in pages of 512 Bytes.
