Description
Atmega8 is an 8-bit AVR microcontroller that is based on RISC CMOS technology and comes with a 28-pin interface for the PDIP package. The Program memory is 8K Flash while RAM and EEPROM are 1K and 512 bytes By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.
respectively. Microchip has been the main source for producing PIC and AVR microcontrollers that are mainly used in embedded and industrial automation systems. These modules can perform a number of functions on a tiny chip, preventing you from spending too much and purchasing external components for laying out automation in the relevant project.
