STM32L4P5 Ultra-Low-Power 32-bit MCUs

STMicroelectronics' ultra-low-power MCU platform is based on proprietary ultra-low-leakage technology. STM32L0 (Arm® Cortex®-M0+), STM32L1 (Cortex-M3), STM32L4, STM32L4+ (Cortex-M4), STM32L5 (Cortex-M33) 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 low current variation between -40°C and +125°C, this ultra-low-power platform has outstandingly low current consumption at elevated temperatures. The MCUs reach the low 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 floating‐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. The STM32L5 series is the answer for embedded applications requiring more security and lower power consumption. It adds more security with Arm Cortex-M33 and its TrustZone® and ST security implementation while using the ultra-low-power technology.
