The STM32L452VEI3TR is a low-power ARM Cortex-M4 microcontroller from STMicroelectronics. It operates at 80MHz and includes 512KB of flash and 160KB of SRAM. The device supports a supply voltage from 1.71V to 3.6V and operates over -40°C to 125°C. Packaged in a 100-UFBGA, it is optimized for space-constrained, energy-efficient applications. Its rich set of peripherals and DMA support make it suitable for IoT, medical, and industrial use.
- Ultra-Low Power: Multiple low-power modes and a 1.71V minimum supply extend battery life in portable devices.
- High-Temperature Tolerance: 125°C rating enables use in automotive and industrial high-heat environments.
- Large SRAM: 160KB RAM supports complex real-time operating systems and large data buffers.
- Compact Package: 100-UFBGA minimizes PCB area, critical for wearables and miniaturized sensors.
IoT Edge Nodes
The 80MHz Cortex-M4 with 160KB RAM handles MQTT/TLS stacks while maintaining low power, enabling battery-powered sensors with 10+ year lifetimes.
Portable Medical Devices
Its 125°C rating and low power consumption suit wearable glucose monitors or insulin pumps that must operate reliably in varying body temperatures.
Smart Building Controllers
With 512KB flash, it stores complex BACnet or Modbus protocols for HVAC and lighting control, while the DMA offloads communication tasks.
Industrial Process Transmitters
The wide temperature range and 1.71V minimum supply allow loop-powered 4-20mA transmitters to operate from a 3.3V rail with high accuracy.
Consumer Wearables
The UFBGA package (5x5mm) enables compact PCB designs for smartwatches, while the low-power modes extend battery life between charges.
Automotive Telematics
With -40°C to 125°C operation, it supports engine-adjacent telematics units for data logging and remote diagnostics.
