Abstract: A nicotine e-vaping device (10) includes a heater (240), a power control circuit (120), and a memory module (210). The heater (240) is configured to heat nicotine pre-vapor formulation. The power control circuit (120) is coupled to the heater (240) through a wire (150). The power control circuit (120) is configured to apply a pulse width modulated power signal to the heater (240) through the wire (150), and to receive information over the wire (150). The memory module (210) is configured to detect a plurality of pulses in the pulse width modulated power signal, record information based on the detected plurality of pulses, and output the recorded information to the power control circuit (120) via the wire (150).
