This research focuses on a comprehensive analysis of the energy efficiency of the Renesas DA16200
microcontroller. The investigation adopts a comparative approach, directly contrasting the power
consumption of the DA16200 with the widely used ESP8266 controller under identical operating conditions.
The primary metric employed to assess energy efficiency is average battery life. Additionally, a detailed
examination of current consumption is conducted across various operational modes, encompassing active
states like data exchange, reception, and transmission, as well as low-power sleep mode. This analysis extends
beyond simply measuring peak current draw. Transient current profiles are captured, providing time-resolved
insights into how current consumption fluctuates throughout different operational phases. This granular data
enables a deeper understanding of the microcontrollers' energy utilization patterns. Furthermore, the research
explores and evaluates techniques for minimizing energy consumption specifically in the ESP8266. These
findings are then juxtaposed against the inherent energy-saving features of the DA16200 microcontroller. To
facilitate a precise and verifiable comparison, a custom test bench accommodating both the DA16200 and
ESP8266 is designed and implemented. This controlled environment ensures consistency in operating
conditions and minimizes external variables that could influence the results. The culmination of this research
is the presentation of a comprehensive analysis, detailing the comparative energy consumption profiles of the
studied microcontrollers. This data forms the foundation for objectively evaluating their suitability for various
low-power the Internet of Things applications.
