STM32L: ULTRA‑LOW‑POWER 32‑BIT MCU SERIESSTM32 and ultra‑low‑powerBy 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.9 PRODUCT SERIES – MORE THAN 40 PRODUCT LINESThe STM32 portfolio offers an extraordinary variety of options including ARM Cortex ‑M cores (M0, M0 , M3, M4, and M7), giving developersflexibility to find the perfect match for their application. Particular attention is paid to make it easy to switch from one device to another. Thecompatibility of binaries combined with the similar pinout assignment, proliferation of hardware IPs and higher‑level programming languagesgreatly facilitates the work of developers.High‑performanceSTM32 F2STM32 F4STM32 F7ST’s ultra‑low‑power MCU platform isbased on a proprietary ultra‑low‑leakagetechnology.STM32L0 (ARM Cortex ‑M0 ), STM32L1(Cortex‑M3), STM32L4 (Cortex‑M4) andSTM8L (8‑bit proprietary core) seriesrepresent a large range of microcontrollersaddressing devices supplied from batteries orthrough energy harvesting and help ensurean optimized cost/performance ratio for allkinds of low‑power applications.With the industry’s lowest currentvariation between ‑40 and 125 C, thisultra‑low‑power platform has outstandinglylow current consumption at elevatedtemperatures.The MCUs reach the industry’s lowest powerconsumption of 350 nA in Stop mode (withSRAM retention), while maintaining a wakeuptime as low as 3.5 µs.The new STM32L4 series is the convergenceof ultra‑low power consumption and highperformance providing 273 CoreMark /217 ULPBench with FPU and DSPinstructions, more memory (up to 1 Mbyte ofFlash memory) and innovative selector guideFree mobile and desktop application to find the right STM32 H745MainstreamUltra‑low‑powerSTM32 F0STM32 F1STM32 F3STM32 L0STM32 L1STM32 L4Cortex‑M0 &M0 Cortex‑M3Cortex‑M4Cortex‑M7macOS
