Working Principle

The LM3S6938-IBZ50-A2 is based on the ARM Cortex-M3 architecture, which is a 32-bit RISC processor. The ARM Cortex-M3 is based on a Harvard architecture, with separate memory and instruction busses, which allows instructions to be fetched and executed simultaneously, giving it an edge over other MCUs in terms of performance. With the additional of Harvard architecture, it also allows for more memory and I/O ports.

Furthermore, this MCU supports a rich range of on-chip peripherals, including ADC, SPI, I2C, UART, Timers and PWMs. This makes the system very versatile, and allows for the development of applications that require complex I/O and control tasks. Additionally, this MCU also supports a wide range of communication protocols, allowing for easy and fast integration into other systems.

The ARM Cortex-M3 also has an asymmetrical interrupt system, meaning that the interrupts can be configured to be triggered after certain events or by certain peripherals. This is particularly beneficial for embedded applications that require fast interrupt handling. Finally, this MCU also offers power management features and power saving modes to ensure that the system is always running efficiently.
