Product Summary
The Atmel AVR ATMEGA8A-8PU is a low-power CMOS 8-bit microcontroller based on the AVR RISC architecture. By executing powerful instructions in a single clock cycle, the ATMEGA8A-AU achieves throughputs approaching 1 MIPS per MHz, allowing the system designer to optimize power consumption versus processing speed.
Parametrics
ATMEGA8A-8PU absolute maximum ratings: (1)Operating Voltages: -2.7 - 5.5V; (2)Speed Grades: 0 - 16MHz; (3)Power Consumption at 4Mhz, 3V, 25℃; (4)Active: 3.6mA; (5)Idle Mode: 1.0mA; (6)Power-down Mode: 0.5μA.
