Core and memory sizing for control-loop duty
The STM32F101RDT6 runs an ARM Cortex-M3 core at 36 MHz — enough throughput for a single RTOS with sensor fusion or a Modbus gateway, but not for real-time audio or fast FFT workloads. The 384 KB flash and 48 KB RAM support a moderate application stack with a lightweight TCP/IP library, though the RAM ceiling limits large data buffers.
Peripheral set for field I/O and communication
The on-chip peripherals cover common industrial and instrumentation needs: DMA for memory-to-peripheral transfers without CPU load, PWM for motor or LED dimming, and a temperature sensor for die-temperature monitoring. The 16-channel 12-bit ADC and dual 12-bit DAC handle basic analog front-end tasks without external converters.
