USI supports SPI and I2C. picoPower technology achieves sub-uA power-down current. 1.8V-5.5V supply for direct battery operation.","working_principle":"The AVR core executes most instructions in a single clock cycle for high code efficiency. 32 general-purpose registers eliminate accumulator bottleneck. The 10-bit SAR ADC converts analog sensors in 65us. USI provides flexible serial communication (SPI or I2C) with minimal firmware. Multiple sleep modes reduce power to 150nA in power-down.","pin_description":"
