Rev 1.0
Hello, and welcome to this presentation on the ULPMark
peripheral profile which measures the energy impact of
common peripheral on deep-sleep and highlights the
benefits offered by the Low-power background
autonomous mode (or LPBAM) of the STM32U5.

• Ultra-Low Power (ULP) is a major challenge for MCU design
• ST deploys creative design techniques to reduce power consumption
• EEMBC ULPMark quantifies these tradeoffs and compares different reference
designs by measuring multiple aspects of MCU energy efficiency
• Each MCU vendor can promote the score of their latest design
• At ST, we measure, certify and publish the scores of all our STM32 families
• Developers are increasingly relying on these scores rather than datasheet figures
for typical power efficiency use cases.
ULPMark overview

Ultra-low power (or ULP) is a major design challenge
facing MCU today, because many systems are battery
powered, especially in the IOT domain.
ST microelectronics deploys creative design techniques
to reduce power consumption. The STM32U5 series
offers advanced power-saving microcontrollers, to meet
the most demanding power/performance requirements
for smart applications.
The Embedded Microprocessor Benchmark Consortium
or EEMBC develops industry-standard benchmarks for
the hardware and software used in autonomous driving,
mobile imaging, the Internet of Things, mobile devices,
and many other applications.
The ULP subcommittee focuses on power and energy.
Scores that are certified have undergone a rigorous
