SAM7SE512/256/32 Summary
The Flash benefits from the integration of a power reset cell and from the brownout detector.
This prevents code corruption during power supply changes, even in the worst conditions.
8.1.2.2
Embedded Flash Controller
The Embedded Flash Controller (EFC) manages accesses performed by the masters of the sys-
tem. It enables reading the Flash and writing the write buffer. It also contains a User Interface,
mapped within the Memory Controller on the APB. The User Interface allows:
programming of the access parameters of the Flash (number of wait states, timings, etc.)
starting commands such as full erase, page erase, page program, NVM bit set, NVM bit
clear, etc.
getting the end status of the last command
getting error status
programming interrupts on the end of the last commands or on errors
The Embedded Flash Controller also provides a dual 32-bit Prefetch Buffer that optimizes 16-bit
access to the Flash. This is particularly efficient when the processor is running in Thumb mode.
Two EFCs (EFC0 and EFC1) are embedded in the SAM7SE512 to control each plane of 256
KBytes. Dual plane organization allows concurrent Read and Program.
One EFC (EFC0) is embedded in the SAM7SE256 to control the single plane 256 KBytes.
One EFC (EFC0) is embedded in the SAM7SE32 to control the single plane 32 KBytes.
8.1.2.3
Lock Regions
The SAM7SE512 Embedded Flash Controller manages 32 lock bits to protect 32 regions of the
flash against inadvertent flash erasing or programming commands. The SAM7SE512 contains
32 lock regions and each lock region contains 64 pages of 256 bytes. Each lock region has a
size of 16 Kbytes.
The SAM7SE256 Embedded Flash Controller manages 16 lock bits to protect 16 regions of the
flash against inadvertent flash erasing or programming commands. The SAM7SE256 contains
16 lock regions and each lock region contains 64 pages of 256 bytes. Each lock region has a
size of 16 Kbytes.
The SAM7SE32 Embedded Flash Controller manages 8 lock bits to protect 8 regions of the
flash against inadvertent flash erasing or programming commands. The SAM7SE32 contains 8
lock regions and each lock region contains 32 pages of 128 bytes. Each lock region has a size of
4 Kbytes.
If a locked-region’s erase or program command occurs, the command is aborted and the EFC
triggers an interrupt.
The 32 (SAM7SE512), 16 (SAM7SE256) or 8 (SAM7SE32) NVM bits are software programma-
ble through the EFC User Interface. The command “Set Lock Bit” enables the protection. The
command “Clear Lock Bit” unlocks the lock region.
Asserting the ERASE pin clears the lock bits, thus unlocking the entire Flash.
8.1.2.4
Security Bit Feature
The SAM7SE512/256/32 features a security bit, based on a specific NVM-bit. When the security
is enabled, any access to the Flash, either through the ICE interface or through the Fast Flash
Programming Interface, is forbidden.
