The working principle of the EFM32PG1B200F256IM32-C0 is based on the ARM Cortex-M3 processor, which is a modified Harvard architecture, a 32 bit RISC microprocessor designed and developed by ARM. The Cortex M3 is a powerful, low-power, and low-cost microcontroller that is optimized for applications requiring high performance and low power consumption. It also supports a wide range of devices, peripherals, communication protocols and low-level drivers, allowing the user to create a wide range of applications.

The Cortex M3 inside the EFM32PG1B200F256IM32-C0 uses a synchronous memory architecture, including 32KB of flash and 256KB of RAM. The processor can understand instructions in low-level languages such as machine and assembly codes. The instructions are executed using two internal buses, the instruction bus and the data bus. The processor also contains several modules that are used for handling memory, communication, and interrupt signals. These modules allow the processor to access data from memory and peripherals quickly, as well as manage interrupts between peripherals and the processor.

The Cortex M3 also includes several on-chip features, such as cache, bus interfaces, and clock controllers. Bus interfaces include AHB and APB bus, both of which allow peripherals to access the processor quickly. The AHB bus is a synchronous bus while the APB bus is a slower asynchronous bus. The processor also includes a JTAG debug interface and a Real-Time Clock to allow users to debug their projects and keep time, respectively. The processor also supports various communication protocols, including UART, SPI, and I2C, which allows the user to interface with peripheral devices quickly.
