Product details

36 MHz Cortex-M3 with 384 KB Flash — what it fits

The STM32F101VDT6TR: STM32F1 value-line family, 36 MHz, 384 KB Flash, 48K x 8 RAM, 80 I/O, 100-LQFP.

The MCU runs from 2.0 V to 3.6 V, which covers both 3.3 V and 2.5 V logic rails without an external regulator. The internal oscillator option saves a crystal on low-cost boards, though the accuracy is adequate for UART timing, not USB.

The DMA engine offloads the CPU for peripheral data transfers, which matters at 36 MHz where every cycle counts. Two 12-bit DAC channels are useful for analog set-point generation or waveform synthesis without an external converter.

There is no last-time-buy risk on the horizon. For dual-sourcing flexibility, the pin-compatible STM32F103VDT6 offers 72 MHz operation and a full-speed USB peripheral — a straightforward drop-in upgrade if the application later needs more performance.

Frequently asked questions

What is the difference between STM32F101VDT6TR and STM32F103VDT6?

The STM32F103VDT6 runs at 72 MHz (double the 36 MHz of this part) and adds a full-speed USB 2.0 peripheral. Both are pin-compatible in the same 100-LQFP footprint, so you can swap between them on the same board — the 103 variant is the upgrade path if you need higher throughput or USB connectivity.

What is the maximum operating frequency of STM32F101VDT6TR?

The core is rated for 36 MHz. The PLL and flash wait-state configuration must be set correctly before raising the clock above the default HSI speed.

Does STM32F101VDT6TR come in tape and reel packaging?

Yes, the 'TR' suffix indicates Tape & Reel packaging, suitable for automated pick-and-place assembly.
