The STM32F100RBT6B from STMicroelectronics is a value-line ARM Cortex-M3 microcontroller designed for cost-sensitive embedded control. It operates at 24MHz with 128KB flash and 8KB SRAM, supporting a wide 2V to 3.6V supply. The device integrates DMA, PWM timers, a temperature sensor, and power management features (PDR, POR, PVD) in a compact 64-LQFP package. Its robust -40°C to 85°C temperature range makes it suitable for industrial and consumer applications requiring reliable performance.
- Cost-effective 32-bit performance: The ARM Cortex-M3 core at 24MHz delivers superior processing power over 8-bit MCUs at a comparable price point.
- Comprehensive analog integration: Built-in temperature sensor and PWM timers reduce external component count, lowering BOM cost.
- Reliable power management: POR/PDR/PVD ensure safe operation during voltage dips, critical for automotive and industrial environments.
- Efficient data movement: DMA controller offloads the CPU for high-throughput sensor data transfer, improving real-time response.
Industrial Sensor Interfaces
The 24MHz Cortex-M3 core with DMA enables efficient data acquisition from multiple analog sensors, while the 2V-3.6V supply range allows direct interfacing with 3.3V industrial transducers.
Motor Control for Small Appliances
With built-in PWM timers and a temperature sensor, this MCU can drive small BLDC or brushed DC motors in fans, pumps, and kitchen appliances, providing closed-loop speed control without external components.
Portable Medical Monitors
The low-voltage operation and low-power features (POR/PVD) make it suitable for handheld glucose meters or pulse oximeters, where battery life and reliable power-on reset are critical.
Building Automation Controllers
Its 128KB flash can store complex control algorithms for HVAC zone controllers or lighting systems, while the 64-LQFP package fits neatly into DIN-rail modules.
Smart Metering
The combination of DMA and multiple timers supports accurate pulse counting and communication protocol handling for water or gas meters, operating over a wide temperature range.
Automotive Aftermarket Accessories
With -40°C to 85°C operation and robust reset circuitry, it can be used in car alarm systems or seat control modules, where voltage fluctuations are common.
