This member has many features similar to that of ATmega But it has reduced number of features dtaasheet capabilities, yet it has enough features to work with. Now let me tell you that if you want to gather knowledge and at the same time want to do it ztmel less cost than the budget of ATmega32you can think of making projects with ATmega8. But rest of the features are available in this IC. Let us see what one can get from ATmega8. Two External Interrupt source, located at port D. Three Internal Timers are available, two 8 bit, one 16 bit, offering various operating modes and supporting internal or external clocking.
SPI Serial Peripheral interface: ATmega8 holds three communication devices integrated. One of them is Serial Peripheral Interface.
Four pins are assigned to Atmega8 to implement this scheme of communication. One of the most powerful communication solutions is USART and ATmega8 supports both synchronous and asynchronous data transfer schemes. It has three pins assigned for that.

In many projects, this module is extensively used for PC-Micro controller communication. It allows designers to set up a commutation between two devices using just two wires along with a common microcntroller connection, As the TWI output is made by means of open collector outputs, thus external pull up resistors are required to make the circuit.
A comparator module is integrated in the IC that provides comparison facility between two voltages connected to the two inputs of the Analog comparator via External pins attached to the micro controller.
Analog to Digital Converter: Inbuilt analog to digital converter can convert an analog input signal into digital data of 10bit resolution. For most of the low end application, this much resolution is enough. Hello, I am going to create a counter teller for our school project. The idea is Everytime the button is pushed the displayed 7 segment digit will increment land display the next digit.
Please reply I really need help. There is many function of this. But Timer just for clocking and can not programmed. Look for ATmega8PU version.
Most of the time it costs close to 89C But wanted to know about its 8KB flash version also. Nice explanation, rest details I will see in Datasheet itself.
