The STM32L100RBT6TR from STMicroelectronics is a low-power ARM Cortex-M3 MCU. It runs at 32MHz with 128KB flash and 16KB RAM. The 64-LQFP package includes an LCD driver, DMA, brown-out detect, and operates from 1.8V to 3.6V.
- Integrated LCD driver – simplifies display interface.
- DMA controller – offloads data transfer from CPU.
- Brown-out detect – prevents data corruption during voltage drops.
- 128KB flash – sufficient for complex applications.
Smart Home Thermostats
LCD driver and 32MHz core enable rich UI with energy monitoring.
Portable Data Loggers
DMA transfers sensor data to flash without CPU intervention.
Industrial Panel Meters
Brown-out detect resets safely during power dips.
Medical Infusion Pumps
PWM controls motor speed; WDT ensures fail-safe operation.
Battery-Powered POS Terminals
1.8V operation extends battery life; 128KB flash stores transaction logs.
Environmental Monitoring Nodes
Low-power modes and LCD display readings in remote locations.
