Microcontroller is a micro computer in an integrated circuit package which contains a microprocessor core, RAM and peripherals. Microcontrollers are processor units aiming at embedded systems. For that reason they are generally used in devices that are automatically controlled. In microcontrollers category Arduino, Raspberry Pi and Adafruit microcontrollers .
The high-performance, low-power Atmel 8-bit AVR RISC-based microcontroller combines 32KB of programmable flash memory, 2KB SRAM, 1KB EEPROM, an 8-channel 10-bit A/D converter, and a JTAG interface for on-chip debugging. The device supports throughput of 16 MIPS at 16 MHz and operates between 4.5-5.5 volts.
By executing instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.
