The ATMEGA8A-AU is a low-power 8-bit AVR microcontroller based on the AVR RISC architecture. It features 8KB of in-system self-programmable Flash memory, 1KB internal SRAM, and 512B EEPROM with high endurance (10,000 Flash and 100,000 EEPROM write/erase cycles). The device operates at a maximum clock frequency of 16 MHz, achieving up to 16 MIPS throughput.
Key electrical specifications include a wide supply voltage range of 2.7V to 5.5V and an operating temperature range of -40°C to 85°C. The microcontroller integrates 23 I/O lines, an 8-channel 10-bit ADC, and peripherals such as two 8-bit timers, one 16-bit timer, three PWM channels, a watchdog timer, and brown-out detection. Communication interfaces include I2C, SPI, and UART/USART.
The ATMEGA8A-AU is packaged in a 32-TQFP (7x7mm) surface-mount package, suitable for compact embedded designs. It supports in-system programming via an on-chip boot program and is fully static for low-power operation. Active power consumption is typically 3.6mA at 4MHz, with idle at 1.0mA and power-down mode as low as 0.5µA.
