STM32U3x5 Series Ultra-Low-Power Embedded MCUs
STMicroelectronics ULP products increase battery lifetime in activity tracking devices
Based 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
