AT91SAM7S Series Summary
The SAM-BA Boot Assistant is a default Boot Program that provides an easy way to program in
situ the on-chip Flash memory.
The SAM-BA Boot Assistant supports serial communication through the DBGU or through the
USB Device Port. (The AT91SAM7S32/16 have no USB Device Port.)
The SAM-BA Boot provides an interface with SAM-BA Graphic User Interface (GUI).
The System Controller manages all vital blocks of the microcontroller: interrupts, clocks, power,
time, debug and reset.
The System Controller peripherals are all mapped to the highest 4 Kbytes of address space,
between addresses 0xFFFF F000 and 0xFFFF FFFF.

peripherals. Note that the memory controller configuration user interface is also mapped within
this address space.
• Communication through the DBGU supports a wide range of crystals from 3 to 20 MHz via
• Communication through the USB Device Port is limited to an 18.432 MHz crystal. (
