Product details

Value-line Cortex-M3 for cost-sensitive control

The part is built for cost-constrained embedded control where the full-featured STM32F103's USB and extra peripherals aren't needed.

At 36 MHz, this MCU handles UART/SPI/I²C communication, PWM generation, and sensor polling without breaking a sweat. The 16 KB Flash is sized for bootloaders, motor-control loops, or simple protocol stacks — think appliance control panels, fan-speed regulators, or basic I/O expanders.

Surface-mount only, so plan for reflow or selective-solder assembly.

Lifecycle and supply outlook

ST lists the STM32F101C4T6A as Active. If you're stocking for a multi-year program, the active status and wide STM32F1 ecosystem make it a low-risk line item.

Frequently asked questions

What is the difference between STM32F101C4T6A and STM32F103C8T6?

The STM32F103C8T6 is a higher-end sibling in the same STM32F1 family. It runs at 72 MHz (vs 36 MHz), packs 64 KB Flash and 20 KB RAM (vs 16 KB / 4 KB), and adds USB, CAN, and two extra SPI/UART peripherals. The STM32F101C4T6A is the cost-optimized entry point for simpler control tasks where those extras aren't needed. Both share the same 48-LQFP footprint, so a board designed for one can often accept the other with a firmware change.
