STM32L5 Ultra-Low-Power Microcontrollers

STMicroelectronics' ultra-low-power microcontrollers add security with Arm® Cortex®-M33 and TrustZone®

Image of STMicroelectronics' STM32L5 Ultra-Low-Power Microcontrollers STMicroelectronics' STM32L5 series of ultra-low-power microcontrollers 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 best-in-class ultra-low-power technology. Offering up to 512 KB of Flash (dual bank) memory and 256 KB of SRAM, the STM32L5 reaches an upgraded level of performance (442 CoreMark) thanks to this core and an ST ART™ accelerator (now also supporting external memory). The STM32L5 offers a large portfolio with seven packages (from 48 to 144 pins) and supports up to +125°C ambient temperature.

Features
  • A full set of security
    • Flexible hardware and software secure isolations with TrustZone
    • Enhanced security services:
      • Dedicated secure user memory space for Secure Boot
      • Symmetric and asymmetric crypto accelerations
      • Memory and IP protection
      • Independent readout protection (RDP) between secure/non-secure domains
      • Active I/O tamper detection
      • Certified cryptolib
      • Embedded secure firmware install loader and ecosystem
  • Power consumption
    • EEMBC™ ULPBench®: 370 ULPMark™-CP score
    • Embedded SMPS step-down converter (optional)
    • Best power consumption numbers with full flexibility:
      • 17 nA in shutdown mode
      • 3 µA in stop mode with full SRAM and peripheral states retention and with 5 µs wake-up time
      • Down to 62 µA/MHz in active mode
