ARM Cortex-M3 at 24 MHz — fit for control-loop and sensor-fusion tasks
The STM32F100VCT6BTR is an STMicroelectronics STM32F1 series microcontroller built around a 32-bit ARM Cortex-M3 core clocked at 24 MHz. That clock rate delivers enough throughput for real-time control loops — motor commutation, sensor fusion, or UART-driven protocol stacks — without the power penalty of a higher-frequency sibling. The 256 KB of on-chip flash and 24 KB of SRAM hold a moderate application image plus stack; the 80 general-purpose I/O lines give headroom for parallel displays or a bank of discrete inputs.
Peripheral set and deployment context
On-chip peripherals include DMA, multiple PWM channels, a temperature sensor, and a watchdog timer — the usual building blocks for a sensor-to-actuator chain. The integrated A/D converter reads 16 channels at 12-bit resolution, and the two D/A converters output 12-bit analog signals — enough for closed-loop analog control without an external DAC. The operating temperature range spans -40°C to 85°C, which covers most industrial enclosures, HVAC zones, and outdoor telecom cabinets.
Package and board integration
The supplier device package is 100-LQFP (14x14), which matches the standard STM32F1 footprint; no exposed pad means the thermal path is through the leads, so forced air or a heatsink is needed if the die dissipates more than a few hundred milliwatts.
No stock-holding claim is made; the supply posture is per-RFQ confirmation. The part is not single-sourced; the STM32F1 family has multiple pin-compatible variants for capacity hedging.
