ARM Cortex microcontroller is the most popular microcontroller in the digital embedded system world. Most industries prefer only ARM microcontroller since it consists of enormous features to implement the products with an advanced appearance. This ARM Microcontroller is cost sensitive and high-performance device which is utilizing in a wide range of applications such as industrial instrument control systems, wireless networking sensors, and automotive body system, etc.
ARM which is stands for Advanced RISC Machine and it is a 32-bit reduced instruction set computer (RISC) microcontroller. In fact, it is the family of the microcontroller developed by different manufacturers such as Motorola and ST Microelectronics. This architecture comes with several versions such as ARMv1, ARMv2, etc. Each has its advantages and disadvantages. As a matter of fact, ARM cortex microcontroller is an High Level Microcontroller in the ARM family. It is divided into three subfamilies such as
The Cortex M3 ARM processor is a high performance that offers the benefits to the developers. It is a hardware architecture that offers separate data and instruction buses for communicating with the RAM and ROM memories. In fact, it is a cost-sensitive device which is utilizing to reduce the processor, and it has the extensive improving system debug capabilities and interrupts handling, etc.
ARM Cortex M3 processor is a very well suited for highly deterministic real-time applications Microcontroller Programming in Embedded and low-cost platforms such as industrial control system, automotive body system, wireless networking and sensors and so on. It is available from several semiconductor manufacturers such as Atmel, NXP, Analog Devices, STMicroelectronics, Toshiba, etc.
Data communication: The processor's low power and high efficiency, couples with thumb 2 instructions, make cortex m3 which is ideal for many communication applications.
Automotive: It has high-performance efficiency and low interrupt latency, allowing to be used in real time systems.
Industrial control: In industrial control applications simplicity, reliability and fast response are the key factors, Cortex M3 has the low interrupt latency so is best suited.
Low-cost microcontrollers: Ideally, it is well suited for low-cost microcontrollers, which is commonly utilizing in consumer products.
Consumer products: It is small, processor and is highly efficient, low in power and supports an MPU enabling complex software to execute while providing robust memory protection.
