STM32 ULP series
From cost smart up to high performance, there is an STM32L series to
match all your memory, analog or peripheral needs.
STM32L: ULTRA‑LOW‑POWER 32‑BIT MCU SERIES
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 and +125°C, this ultra‑low‑power platform has outstandingly 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 STM32L4 series offers the excellence of ST’s ultra‐low‐power platform with an additional performance dimension by providing
100 DMIPS with DSP instructions and oating‐point unit (FPU), more memory (up to 1 Mbyte of Flash memory) and innovative features.
The STM32L4+ series extends STM32L4 technology by offering higher performance (120 MHz/409 CoreMark executing from internal Flash
memory), larger embedded memories (up to 2 Mbytes of Flash memory and 640 Kbytes of SRAM), and more advanced graphic features with no
compromise on its ultra‑low power consumption capability.
