The RL78 is an interesting choice for the reference design target. If I remember correctly, this MCU has a special Snooze Mode that puts the device into a low power mode that can handle simple interface requirements without CPU overhead. Maybe this mode is being used to reduce power even more than standard low power techniques?
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
