By shrinking the technology and reducing the energy requirements of integrated circuits, producing ultra-low-power devices has practically become possible. Texas Instruments as a pioneer in developing FRAM-based products announced a couple of different MicroController Unit (MCU) families based on the low-power and fast Ferroelectric RAM technology. Such MCUs come with embedded cryptographic module(s) as well as the assertion that due to the underlying ultra-low-power technology mounting successful Side-Channel Analysis (SCA) attacks has become very difficult. In this paper, the authors practically evaluate this claimed hardness by means of state-of-the-art power analysis attacks.
