Working Principle

The AT91SAM7S32-MU uses an ARM7TDMI-S processor-based architecture. This architecture feature a 16-bit or 32-bit instruction set, a 3-stage instruction pipeline, and a low power clock cycle. The device also includes 16Kbytes of SRAM for fast data storage, 8Kbytes of ROM for storing programs and data, and 128KBytes of on-board flash memory.

The external bus interface offers a way to access external memories and peripherals, while the flexible analogue inputs/outputs provide a host of analogue features. The device also features enhanced power management functions and can be reset remotely by means of a reset pin.

The AT91SAM7S32-MU combines internal and external features to allow for high performance and low power operation. This is done by optimizing the instruction and data caches, tightly coupling peripherals to the processor, and providing a wide range of software support for product development and debugging.

The device also offers powerful and flexible system-level debug capabilities, which allow for debugging at the instruction level, in real-time. The debugger can access the flash memory, and can be used to program and erase the memory. The device also supports time triggering, so that complex debugging jobs can be undertaken quickly and efficiently.
