megaAVR® CMOS 8-bit MicrocontrollersMicrochip Technology megaAVR ® CMOS 8-bit Microcontrollers are low-power microcontrollers that are based on the AVR ® enhanced RISC architecture. The devices like ATmega164A, ATmega164PA, ATmega324A, ATmega324PA, ATmega644A, ATmega644PA, ATmega1284, and ATmega1284P fall under the megaAVR category of microcontrollers. These devices feature 16KB to 128KB FLASH memory, 1KB to 16KB SRAM, and 512bytes to 4KB EEPROM. The megaAVR devices execute instructions in a single clock cycle that helps the CPU to achieve a throughput of one Million Instructions Per Second (MIPS) per megahertz. This allows the system designer to optimize power consumption versus processing speed.
