Functional Overview

● ARM®-Cortex®-M0 core

A sort of 32-bit RISC processor for embedded devices produced by the ARM Corporation is called the ARM® Cortex®-M0. It was designed to be a low-cost platform that can implement MCUs. It requires less power and has fewer pins than other platforms, yet it nevertheless performs exceptionally well in terms of computation and reacts quickly to interruptions. What one would anticipate from an ARM core is the extremely efficient code of the ARM® Cortex®-M0 processors. Also, they provide memory capacities that are typically found in 8-bit and 16-bit devices. The STM32F051xx devices include ARM cores, making it possible to utilize any ARM tools and software with them.

● Cyclic redundancy check calculation unit (CRC)

A 32-bit data word and a CRC-32 (Ethernet) polynomial are used to generate a CRC code using the CRC (cyclic redundancy check) computation unit. CRC-based algorithms are used, among other things, to check the accuracy of data transfer or storage. They provide a way to check the integrity of the Flash memory within the parameters of the EN/IEC 60335-1 standard. To compare the software’s runtime signature to a reference signature created at link-time and saved at a specific memory location, the CRC calculation unit is used.

● Clocks and startup

However, the internal RC 8 MHz oscillator is chosen as the default CPU clock on reset. The system clock is selected on startup. There is an option to pick an external 4-32 MHz clock, in which case its health is checked. The system immediately returns to the internal RC oscillator whenever a failure is found. When enabled, a program interrupt is produced. Likewise, when required, full interrupt management of the PLL clock entry is provided. The application may adjust the AHB and APB domain frequencies using a variety of prescalers. AHB and APB domains can operate at a maximum frequency of 48 MHz.
