Working Principle
The STM32F100RCT7B microcontroller works by executing instructions and manipulating data stored in its memory. Its main features are its ARM Cortex-M3 core, 48 MHz maximum CPU frequency, 12-bit ADC and 12 timers, up to 5 supported peripherals, USB 2.0 Host/Device, I2C, SPI and CAN 2.0 B, and RTC, 3 x PWMs and 3 x watchdog timers. It also has an operating voltage range of 1.7V to 3.6V and an operating temperature range of -40°C to 105°C.
The microcontroller has a 32-bit Harvard architecture with separate instruction and data buses. Its instruction bus can hold instructions to be executed by the microcontroller and its data bus is used to store data to be operated upon by the instructions. The instructions and data are stored in memory such as the SRAM, ROM, and Flash, and are then transferred to the microcontroller for execution.
The microcontroller follows a CPU cycle which is executed in four steps – Instruction Fetch, Instruction Decode, Execute and Write Back. In the Instruction Fetch step, the microcontroller retrieves an instruction from the memory and starts reading its content. In the Instruction Decode step, the microcontroller decodes the instruction and determines what it needs to do. In the Execute step, the microcontroller executes the instruction and performs the required operation. Lastly, in the Write Back step, the microcontroller returns the result of the operation to the memory. This process is repeated until the end of a program is reached.
Conclusion
In conclusion, the STM32F100RCT7B microcontroller is a low cost, low power, 32-bit microcontroller suitable for a wide range of embedded applications. It is capable of executing instructions stored in its memory and provides features such as an ARM Cortex-M3 core, USB 2.0 Host/Device, I2C, SPI, CAN 2.0 B, and 12 timers. It also has an operating voltage range of 1.7V to 3.6V and an operating temperature range of -40°C to 105°C.
