STM32U3x5 Series Ultra-Low-Power Embedded MCUs

STMicroelectronics ULP products increase battery lifetime in activity tracking devices

Image of STMicroelectronics STM32U3x5 Series Ultra-Low-Power Embedded MCUsBased on innovative subthreshold technology, this STMicroelectronics series of ULP products increases battery lifetime in activity tracking devices by a factor of 7 compared with previous generations (enabling longer device use). Based on an Arm® Cortex®-M33 with extended memory (1 MB of Flash and 256 KB of SRAM), STM32U3 products support standard and extended industrial temperature (-40°C/+85°C and +105°C), making it the perfect choice for industrial applications. The STM32U385x product types offer cryptography features.

Features
  • Lower power consumption: subthreshold technology
  • Higher security: asymmetric key hardware protection in ST factory certificate provisioning
  • New and updated IP: I3C and CAN FD
  • Lower cost versus STM32U5
Applications
  • Industrial: thermostats, smoke detectors, heat cost allocators, door locks, asset trackers, sensors
  • Medical: insulin pumps, glucose meters
  • Smart metering: water, gas, electricity meters, smart home gateways
  • Consumer: activity trackers, GPS, e-cigarettes, headphones, PC accessories
