The ATmega48A-AU is a low power, CMOS 8-bit microcontroller based on the AVR® enhanced RISC architecture. It executes instructions in a single clock cycle, achieving CPU throughput approaching one million instructions per second (MIPS) per megahertz. This allows system designers to optimize power consumption versus processing speed.
It features QTouch library support for capacitive touch buttons, sliders, and wheels, with up to 64 sense channels. The microcontroller also includes various peripheral features such as timers/counters, PWM channels, ADC, temperature measurement, serial interfaces, and more.
With special microcontroller features like power-on reset, programmable brown-out detection, and multiple sleep modes, the ATmega48A-AU offers flexibility and efficiency in various applications.
