SAM4E [DATASHEET]

Atmel-11157D-ATARM-SAM4E16-SAM4E8-Datasheet_12-Jun-14

The SAM4E device (1024 Kbytes) embeds a total of 128-Kbyte 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.

®

), 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 to consist of 2 sectors of 8 Kbytes and 1 sector of 48 Kbytes. Refer to
