Atmel's new ATMega8A 8-Bit Microcontroller. Has 8 KB of program space, 23 I/O pins, 6 ADC pins, USART, maximum speed of 16 Mhz, can be programmed in circuit and has a wide operating voltage range between 2.7V and 5.5 V.

Note: The Atmega8A is a newer version of the older and popular Atmgea8. Both the microcontrollers are completely compatible with each other but the Atmega8A offers better, performance in terms of power consumption and operating frequency apart from other minor differences.
