Working Principle

The AT91SAM7S64-MU-999 is based on the ARM7TDMI-S processor core. This processor core is designed to perform a variety of tasks, including computational and control-oriented tasks. It does this by utilizing a RISC instruction set, which is much simpler and more efficient than traditional CISC instruction sets.

The ARM7TDMI-S core also utilizes memory-mapped I/O, which is a mechanism that allows the processor to access memory and peripheral devices directly. This reduces the number of separates address buses needed and increases the amount of efficient and accurate data that can be transferred.Other features of the ARM7TDMI-S core include a 32-bit data bus, a 32-bit address bus, and a 32-bit ALU data path.

The AT91SAM7S64-MU-999 also includes 128 KB of embedded nonvolatile Flash memory. The Flash memory is divided into 8 blocks of 16 KB each. This allows for 8-bit parallel access and a maximum write/erase cycle of 25,000. The Flash memory can store both program and data and is typically used for storing infrequently changed application code, such as boot code, vector tables, and interrupt handlers.

The AT91SAM7S64-MU-999 also includes 48 KB of embedded SRAM memory. The SRAM memory is divided into 8 blocks of 8 KB each. This allows for 8-bit parallel access and is typically used for storing frequently changed application data such as variables, lookup tables, and other runtime data.

Overall, the AT91SAM7S64-MU-999 is a powerful and versatile Embedded Microcontroller that offers a wide range of features and applications. Its combination of performance, affordability, and integration make it an ideal solution for any application.
