ARM stands for Advanced RISC Machines where RISC stands for Reduced Instruction Sets Computer.
The ARM Cortex M0 processor is an eligible choice for Energy Efficient Embedded Products. The features of these processors are Low Power usage, Highly Energy efficient, faster Input/output access, high performance, Easy to use and Debug and Ready for Future applications.
Embedded Products now days need even longer battery life but of course without any compromise on performance. This increases the possibility of processors based on Cortex M0 Architecture in the Embedded Products that needs longer battery backups. The small silicon area of the microcontroller consists of only 12K gates with low powering techniques like SRPG, Clock gating and power gating. The 2 stage pipeline structure of M0 processor reduces the ratio between combinational gates and flip-flops leads to higher Energy efficiency. The Architecture of processor defines 3 levels of sleeping modes these are Active mode, Deep Sleep and Deep sleep with SPRG support that leads the microcontroller to usage of Nano Watts’s power profile with instant wakeup.
The chip size of Cortex M0 processor is very small as compared to the other Cortex microcontrollers. The size matters in small size applications like sensors, Mobile applications, Touch Sensing equipments and medical equipments. These microprocessors can be used as a cost efficient high speed transmission of communication protocols like UART, SPI, I2C, USB, RS232, I2S and also Memory Card Interface. These Controllers can be used in the products like music players, Mass storage devices, Energy meters, GPS systems, Small sized spying devices, automobiles, biometrics, Web based applications etc. The Cortex M0 microcontroller has an EEPROM write cycles of 1Million times and unlimited read cycles. ARM microcontrollers are revolutionary and have limitless possibilities. ARM microcontrollers comes with multiple SPI ports, I2C and UART ports which is the Duplex and fastest communication protocol between microcontrollers and ASICs. In my next blog I will share methods to program easy communication between microcontrollers using UART through which you will be able to network multiple microcontrollers and build a high functional system with communicative networks.
