ATmega16 is an 8-bit high performance microcontroller from the Atmel’s Mega AVR family. Atmega16 is a 40 pin microcontroller based on enhanced RISC (Reduced Instruction Set Computing) architecture with 131 powerful instructions. It has a 16 KB programmable flash memory, static RAM of 1 KB and EEPROM of 512 Bytes. The endurance cycle of flash memory and EEPROM is 10,000 and 100,000, respectively. Most of the instructions execute in one machine cycle. It can work on a maximum frequency of 16MHz. ATmega16 pin diagram should clarify things a bit.
