ATmega8 and ATmega8L detail Datasheet (8 bit processor, 8051 family microcontroller)

This datasheet is common for microcontroller ATmega8 and ATmega8L. Difference between ATmega8 and ATmega8L is only that ATmega is operated on (4.5 - 5.5)V supply voltage and ATmega8L is opertaed on (2.7 - 5.5)V. And due to low voltage operation of ATmega8L, its maximum speed grade is 8Mhz on ther other hand ATmega8 has 16Mhz maximum speed grade
