Introduction

This datasheet provides the ordering information and mechanical device characteristics of
the STM32L151xE and STM32L152xE ultra-low-power ARM
microcontroller product line. STM32L151xE and STM32L152xE devices are
microcontrollers with a Flash memory density of 512 Kbytes.
The ultra-low-power STM32L151xE and STM32L152xE family includes devices in 5
different package types: from 64 pins to 144 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 ultra-low-power STM32L151xE and STM32L152xE
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 STM32L151xE and STM32L152xE datasheet should be read in conjunction with the
STM32L1xxxx reference manual (RM0038). The application note "Getting started with
STM32L1xxxx hardware development" (AN3216) gives a hardware implementation
overview. Both documents are available from the STMicroelectronics website www.st.com.
