STM32L5 Ultra-Low-Power Microcontrollers
STMicroelectronics' ultra-low-power microcontrollers add security with Arm® Cortex®-M33 and TrustZone®
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.
