Embedded Flash
Enhanced Embedded Flash Controller
Lock Regions
The SAM-BA Boot provides an interface with SAM-BA Graphic User Interface (GUI).
The Flash of the AT91SAM9XE128/256/512 is organized in 256/512/1024 pages of 512 bytes
directly connected to the 32-bit internal bus. Each page contains 128 words.
The Flash contains a 512-byte write buffer allowing the programming of a page. This buffer is
write-only as 128 32-bit words, and accessible all along the 1-Mbyte address space, so that
each word can be written at its final address.
The Flash benefits from the integration of a power reset cell and from a brownout detector to
prevent code corruption during power supply changes, even in the worst conditions.
The Enhanced Embedded Flash Controller (EEFC) is continuously clocked.
The Enhanced Embedded Flash Controller (EEFC) is a slave for the bus matrix and is configu-
rable through its User Interface on the APB bus. It ensures the interface of the Flash block with
the 32-bit internal bus. Its 128-bit wide memory interface increases performance, four 32-bit data
are read during each access, this multiply the throughput by 4 in case of consecutive data.
It also manages the programming, erasing, locking and unlocking sequences of the Flash using
a full set of commands. One of the commands returns the embedded Flash descriptor definition
that informs the system about the Flash organization, thus making the software generic pro-
gramming of the access parameters of the Flash (number of wait states, timings, etc.)
The memory plane of 128, 256 or 512 Kbytes is organized in 8, 16 or 32 locked regions of 32
pages each. Each lock region can be locked independently, so that the software protects the
first memory plane against erroneous programming:
If a locked-regions erase or program command occurs, the command is aborted and the EEFC
could trigger an interrupt.
The Lock bits are software programmable through the EEFC 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.
• Communication through the DBGU supports a wide range of crystals from 3 to 20 MHz via
• Communication through the USB Device Port is depends on crystal selected:
software auto-detection.
– limited to an 18,432 Hz crystal if the internal RC oscillator is selected
– supports a wide range of crystals from 3 to 20 MHz if the 32,768 Hz crystal is
selected
