Abstract

This paper addresses automotive low power technologies in Internet of Things (IoT) societies, where the interaction among cloud information, real-time recognition and vehicle control is a key. High reliability and high performance with low power under the harsh operating conditions are strongly demanded for automotive microcontroller units (MCUs). Our developed embedded Flash (eFlash) and SRAM achieved those required performance at up to Tj=170°C mainly for the vehicle control solution. To perform the highly robust computation in car information applications, the power management involving adaptive voltage scaling and real time power saving are adopted. Moreover other low-power schemes such as multi core CPU system with the easier parallelism and the digitally assisted ADC are introduced.
