The ATMEGA8-16PU is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATMEGA8 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. It features 8K Bytes of In-System Self-Programmable Flash program memory, 512 Bytes EEPROM, 1K Byte SRAM, 6 general purpose I/O lines, 32 general purpose working registers, three flexible Timer/Counters with compare modes, Internal and External Interrupts, a serial programmable USART, a byte oriented Two-wire Serial Interface, a 6-channel ADC (TQFP and MLF packages), a programmable Watchdog Timer with internal Oscillator, an SPI serial port and five software selectable power saving modes. The device operates between 2.7-5.5 volts.
