System On Chip (SoC) technology plays a vital role in the design of embedded systems. It is used to integrate multiple separate functions, such as processors and memory, onto one piece of silicon. The M2S025-VFG400 is one such SoC developed by M2S. This article will discuss the application fields and working principle of the M2S025-VFG400.

The M2S025-VFG400 is a powerful, low-power Arm Cortex-M33 SoC. It is designed for use in applications ranging from low-end IoT devices to automotive, industrial, aviation, and medical markets. It is optimized for memory and performance, and has a large range of peripherals such as UART, I2C, SPI, ADC, DAC, and Timers. The device also offers built-in security features such as Arm TrustZone and secure boot. The M2S025-VFG400 can be used in applications such as measurement and control, data acquisition and control, data logging networks, industrial automation, automotive embedded systems and more.

The M2S025-VFG400 is designed for industrial environments and is capable of handling high levels of thermal shock and vibration. It has an embedded on-chip 62KB SRAM, 64kB instruction cache, and 24kB data cache. The device utilizes a power-saving sleep mode and is capable of operating at temperatures ranging from -40°C to +85°C.

In terms of architecture, the M2S025-VFG400 offers three main components: a processor cluster, an interconnect bus, and a peripheral bus. The processor cluster consists of two ARM® Cortex®-M33 processors, which are integrated using a Symmetric Multiprocessing (SMP) architecture. The interconnect bus allows the processors and peripherals to communicate with each other, and is capable of supporting up to eight cores. The peripheral bus consists of Discrete Units (DU), which interface with the processor cluster, and can be used for tasks such as communications, data storage, and peripherals. The DU is also connected to the main memory, allowing access to shared resources.

The M2S025-VFG400 uses a neat design to achieve its goal of low power consumption and high performance. The processor cluster and peripheral bus are connected to the main system by a dedicated low power and low latency power management unit (PMU). The PMU allows efficient power management of the SoC, allowing components to enter power-save modes and reducing overall power consumption.

The M2S025-VFG400 utilises a flexible system on chip (SoC) bus architecture. This architecture utilises two buses (the Core Bus and the Peripheral Bus). The Core Bus is used for the cores and supporting architecture, and is divided into two separate streams (Instruction Stream and Data Stream). The Peripheral Bus is used for connecting peripherals to the processor cluster. Each bus is tightly coupled to its corresponding component, ensuring low latency and high performance.

The M2S025-VFG400 also provides protection against various security threats. This is thanks to its on-chip security features such as TrustZone, secure boot, and secure storage. TrustZone provides a secured space where data and applications can be stored safely, while secure boot prevents unauthorized code from being executed. Secure storage allows data to be encrypted, preventing access by unauthorized users.

In conclusion, the M2S025-VFG400 is a powerful and low-power ARM Cortex-M33 SoC. It is designed to integrate multiple functions onto one piece of silicon, including a processor cluster, interconnect bus and peripheral bus. The device is also optimized for memory and performance, and can operate in a wide range of environments. Finally, it offers a range of security features, such as TrustZone, secure boot and secure storage, making it ideal for applications that require secure data handling.
