Product details

36 MHz ARM Cortex-M3 with 768 KB Flash — value-line density option

It packs 768 KB of Flash and 80 KB of SRAM, enough for moderate code and data buffers in sensor fusion, motor control, or HMI panels. The 51 GPIOs and the peripheral set — DMA, multiple PWMs, a 16-channel 12-bit ADC, and a dual 12-bit DAC — let you consolidate several board-level functions onto a single die.

If you are looking for a second-source hedge, the pin-compatible STM32F103RFT6 runs at 72 MHz and adds a USB interface — check whether your firmware can tolerate the faster core and the extra peripheral.

Programming and debug

Programmed through the standard STM32 serial wire debug (SWD) interface. The internal oscillator means the chip can run code without an external crystal for low-accuracy timing; for CAN or USB you will still want a precision external clock. The 64-LQFP package leaves the SWD pins accessible without crowding.

Frequently asked questions

What is the closest pin-compatible alternative to STM32F101RFT6TR in this component family?

The STM32F103RFT6 is pin-compatible and shares the same 64-LQFP footprint. It runs at 72 MHz (double the 36 MHz of the F101) and adds USB connectivity. If your design can handle the higher core speed and the extra peripheral, it is a direct drop-in replacement for dual-sourcing.

How to program STM32F101RFT6TR?

Use the standard STM32 serial wire debug (SWD) interface via a programmer such as the ST-Link/V2. The internal oscillator allows code execution without an external crystal for non-timing-critical applications.
