System On Chip (SoC) technology quickly emerged in the embedded market to enable new products with increased capabilities. SoC technology combines the extremely complex and powerful processors, memory, and communications modules on the same chip. This enables a dramatic reduction in system size, power consumption, and cost. An example of this is the M2S090-1FG484I. This chip can be used in multiple applications, and its working principle will be discussed in detail in this paper.

The M2S090-1FG484I is an ARM Cortex-M0+ processor SoC with an integrated 16-bit ADC and 256 KB of internal Flash memory. This processor operates up to 100 MHz and is 32-bit ARM microcontroller. It is based on a 32-bit RISC processor with high-speed 2D graphics engine, low power RAM and ROM, and Direct Memory Access (DMA) controller. Its main features include 64-pin LQFP package, on-chip oscillator, PLL/multi-clock, memory management unit, embedded trace buffer and memory protection unit.

The M2S090-1FG484I is used in various applications, for example, in automotive applications such as engine control units (ECU), airbag control modules, body electronics, and luxury door control. In consumer and industrial markets, it is used for remote control applications such as remote controller, home automation, energy metering, vending machine, healthcare and security. Additionally, it can also be used in robotics, point of sales systems, building monitoring systems and data loggers.

The working principle of the M2S090-1FG484I is quite straightforward. It is based on the ARM Cortex-M0+ 32-bit RISC processor which runs at up to 100MHz and features a 2D graphics engine, embedded RAM and ROM, PLL/multi-clock, and Direct Memory Access (DMA) controller. The integrated 16-bit ADC provides flexibility for analog signal processing, while the 256 Kbytes of internal Flash memory is sufficient for code, data, and parameter storage. When powering up, the processor fetches instructions from the Flash memory and begins executing them according to the instructions stored in the memory. Depending on the instructions, it can access the RAM or ROM and execute the instructions from it. The processor also has a multi-clock system that allows it to manage the power consumption and clock speed depending on the application. Furthermore, the DMA controller allows the processor to access external peripherals without consuming CPU time.

In addition, the processor also contains a debugging logic to help with programming and debugging the processor’s code. It also has a memory protection unit which prevents the system from crashing due to memory or data corruption. Finally, the embedded trace buffer enables logging and debugging of the processor’s performance. With this tracing data, developers can better understand the processor’s behavior and optimize its performance.

In conclusion, the M2S090-1FG484I is an example of SoC technology: a powerful and versatile processor system with integrated peripherals and enhanced features. It can be used in a wide range of applications. Its working principle is based on the ARM Cortex-M0+ 32-bit RISC processor which runs at high speed and can access multiple peripherals without consuming CPU time. Additionally, it has numerous debugging, logging, and memory protection features that help developers to program and debug embedded systems with ease and accuracy.
