Product Summary

The ATMEGA8A 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 achieves throughputs approaching 1 MIPS per MHz, allowing the system designer to optimize power consumption versus processing speed.

Parametrics

ATMEGA8A absolute maximum ratings: (1)Operating Temperature: -55℃ to +125℃ ; (2)Storage Temperature: -65℃ to +150℃; (3)Voltage on any Pin except RESET with respect to Ground: -0.5V to VCC+0.5V; (4) Voltage on RESET with respect to Ground: -0.5V to +13.0V; (5) Maximum Operating Voltage: 6.0V; (6)DC Current per I/O Pin: 40.0mA; (7)DC Current VCC and GND Pins: 300.0mA.

Features

ATMEGA8A features: (1)High-performance, Low-power AVR 8-bit Microcontroller; (2)I/O and Packages: 23 Programmable I/O Lines; 28-lead PDIP, 32-lead TQFP, and 32-pad QFN/MLF; (3)Operating Voltages: 2.7 - 5.5V; (4)Speed Grades: 0 - 16 MHz; (5)Power Consumption at 4MHz, 3V, 25℃: Active: 3.6mA; Idle Mode: 1.0mA; Power-down Mode: 0.5μA; (6) Advanced RISC Architecture: 130 Powerful Instructions – Most Single-clock Cycle Execution; 32 × 8 General Purpose Working Registers; Fully Static Operation; Up to 16 MIPS Throughput at 16 MHz; On-chip 2-cycle Multiplier.
