STM32L: ULTRA‑LOW‑POWER 32‑BIT MCU SERIES
STM32 and ultra‑low‑power
9 PRODUCT SERIES – MORE THAN 30 PRODUCT LINES
ST’s ultra‑low‑power MCU platform is
based on a proprietary ultra‑low‑leakage
technology.
STM32L0 (ARM® Cortex®‑M0+), STM32L1
(Cortex‑M3), STM32L4 (Cortex‑M4) and
STM8L (8‑bit proprietary core) series
represent a large range of microcontrollers
addressing devices supplied from batteries or
through energy harvesting and help ensure
an optimized cost/performance ratio for all
kinds of low‑power applications.
With the industry’s lowest current variation
between ‑40°C and +125°C, this
ultra‑low‑power platform has outstandingly
The STM32 portfolio offers an extraordinary variety of options including ARM® Cortex®‑M cores (M0, M0+, M3, M4, and M7), giving developers
flexibility to find the perfect match for their application. Particular attention is paid to make it easy to switch from one device to another. The
compatibility of binaries combined with the similar pinout assignment, proliferation of hardware IPs and higher‑level programming languages
greatly facilitates the work of developers.

By choosing an STM32 microcontroller for your embedded application,
you gain from our market‑leading expertise in MCU architecture,
technology, multi‑source manufacturing and long‑term supply.
Highperformance
STM32 F2
STM32 F4
low current consumption at elevated
temperatures.
The MCUs reach the industry’s lowest power
consumption of 350 nA in Stop mode (with
SRAM retention), while maintaining a wakeup
time as low as 3.5 µs.
The new STM32L4 series is the convergence
of ultra‑low power consumption and high
performance providing 273 CoreMark® /
176.7 ULPBench™ (188 using an external
DC/DC converter) with FPU and DSP
instructions, more memory (up to 1 Mbyte of
Flash) and innovative features.

STM32 Nucleo development boards can easily be expanded through a variety of add-on boards. These expansion boards open the door to any
type of application leveraging the appropriate mix of performance/peripherals/power within the comprehensive STM32 family.
Each expansion board integrates the necessary components to implement specialized features of a chosen application, and comes with
complementary STM32 software modules.

ST proposes a 3‑step approach for standard development in C:
1/ Configure the microcontroller using STM32CubeMX tool and optionally generate code depending on user choices
2/ Develop the application, compile and debug, using a free or commercial integrated development environment (IDE) from a partner such as:
IAR, Keil*, AC6, Atollic, Coocox, Emprog, iSystem, Keolabs, Rowley, Segger, Tasking.
3/ Monitor the application while it is running without being intrusive with STMStudio.

Within STM32CubeMX, use the Power Consumption Calculator wizard: build your own chip configuration, select battery type or configure your
own, define a sequence of steps representing your application : Obtain power consumption and battery life results.
The ST’s embedded software offer around the STM32 microcontroller family proposes 4 different combinations of portability and optimization
criteria:
• STM32Snippets: a collection of highly optimized code examples using direct register access
• Standard Peripheral Library: ensures portability at STM32 series level; for example, easy portability within STM32L1 series
• STM32Cube embedded software: ensures portability at STM32 family level; facilitating application re‑use from one STM32 MCU to another
• CMSIS Driver and mbed abstraction layer: microcontroller abstraction for any Cortex‑M‑based microcontroller
• Solutions beyond the microcontroller world: STM32Java, .Net Micro framework, or MATLAB/Simulink

USAGE RECOMMANDATIONS
• STM32L0 users:
STM32Snippets allow users to control the hardware with minimal software overhead
therefore optimizing power consumption (order code: STM32SnippetsL0)
• STM32L1 users:
• If only STM32L1 MCUs are required, the Standard Peripheral Library is a good choice,
ensuring a portability level between all STM32L1 devices (order code: STSW‑STM32077)
• STM32 portability needs:
• STM32Cube is the best answer when high level of portability is required (order codes:
STM32CubeL0, STM32CubeL1 and STM32CubeL4)
