ATMEGA8A-AUR

The ATMEGA8A-AUR is a low-power CMOS 8-bit microcontroller based on the AVR RISC architecture, manufactured by Atmel (now Microchip Technology). It achieves throughputs approaching 1 MIPS per MHz, allowing optimization of power consumption versus processing speed. The device features 8KB of in-system self-programmable Flash memory, 1KB internal SRAM, and 512B EEPROM with high endurance (10,000 write/erase cycles for Flash, 100,000 for EEPROM). Data retention is rated at 20 years at 85°C and 100 years at 25°C.

Key peripheral features include two 8-bit timer/counters, one 16-bit timer/counter with capture mode, three PWM channels, an 8-channel 10-bit ADC, and multiple serial interfaces (I²C, SPI, UART/USART). The microcontroller also includes a programmable watchdog timer, brown-out detection, and an on-chip analog comparator. It operates over a supply voltage range of 2.7V to 5.5V and a temperature range of -40°C to 85°C.

The device is available in a 32-pin TQFP surface-mount package (7x7mm). It is suitable for a wide range of embedded applications including industrial control, automotive, consumer electronics, and sensor interfaces. The AVR architecture provides a rich instruction set and efficient code execution.
