Different Microcontrollers and their Applications: The AVR microcontrollers are based on advanced RISC architecture. As well as, the ATmega32 is a low power of the CMOS 8-bit microcontroller based on the AVR will develop RISC architecture. AVR will execute 1 million instructions per second if its cycle frequency is 1MHz.
A 8051 Microcontroller is one of the terms in Computer-on-a-Chip. It is not only the CPU but also I/O ports, RAM, Timer/Counter, ROM, Serial I/Os all are put together among the single microcontroller chip.
Microcontrollers are one of the task-specific and are mainly used for making the Embedded Systems. In fact, we need electronic automation as well as we use a microcontroller. The application area of microcontrollers is so huge, probably we won’t be able to finishing up listing them all.
Tiny AVR: As a matter of fact, the microcontroller contains Less memory, minimum in size, apt only for simpler applications.
Mega AVR: In this microcontroller the most popular ones having a perfect amount of memory up to 256KB, and fit among the modest to difficult applications.
Xmega AVR:This microcontroller is utilized commercially for compound applications, which requires large program memory and also high speed.
In order to, AVR Training Course executes most of the instructions in a single execution cycle. We know that AVRs is 4 times faster than the PICs, it will consume less power and it will operate into several power-saving modes. Let us do a comparison between the three most commonly used families of the microcontrollers.
Especially, AVR is the 8-bit microcontroller belonging to the family of the reduced instruction set computer (RISC). In this RISC architecture, the instruction set of the computer may not fewer in a number. But also it is simpler and faster in the operation.
