Recently there has been increased demand for not only ultra-low power, but also high performance, even in standby-power-critical applications. Sensor nodes, for example, need a microcontroller unit (MCU) that has the ability to process signals and compress data immediately. A previously reported 130nm CMOS and FeRAM-based MCU features zero-standby power and fast wakeup operation by incorporating FeRAM devices into logic circuits [1]. The 8MHz speed, however, was not sufficiently high to meet application requirements, and the FeRAM process also has drawbacks: low compatibility with standard CMOS, and write endurance limitations. A spintronics-based nonvolatile integrated circuit is a promising option to achieve zero standby power and high-speed operation, along with compatibility with CMOS processes. In this work, we demonstrate a fully nonvolatile 16b MCU using 90nm standard CMOS and three-terminal SpinRAM technology. It achieves 20MHz, 145μW/MHz operation with a 1V supply in the active state, and 4.5μW intermittent operation with 120ns wakeup time and 0.1% active ratio, without forwarding of re-boot code from memory. The features provide sufficiently long battery life to achieve maintenance-free sensor nodes.
