1 Introduction
This datasheet provides the ordering information and mechanical device characteristics of
the STM32L151xx and STM32L152xx ultralow power ARM Cortex-M3 based
microcontrollers product line.
The ultralow power STM32L15xxx family includes devices in 3 different package types: from
48 to 100 pins. Depending on the device chosen, different sets of peripherals are included,
the description below gives an overview of the complete range of peripherals proposed in
this family.
These features make the ultralow power STM32L15xxx microcontroller family suitable for a
wide range of applications:
• Medical and handheld equipment
• Application control and user interface
• PC peripherals, gaming, GPS and sport equipment
• Alarm systems, Wired and wireless sensors, Video intercom
• Utility metering
This STM32L151xx and STM32L152xx datasheet should be read in conjunction with the
STM32L1xxxx reference manual (RM0038).
The document "Getting started with STM32L1xxx hardware development” AN3216 gives a
hardware implementation overview. The both documents are available from the
STMicroelectronics website www.st.com.
