How suffixes on STM32F301 map to package, grade, and reel options.

How to Choose the Right STM32F301 Microcontrollers

📦

Match the footprint first

Packages here: 32-UFQFN Exposed Pad. Open the land-pattern drawing before you substitute a different suffix.

Electrical headroom

Compare voltage and current columns in the variant table. For STM32F301, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.

🌡️

Temp grade letter matters

Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.

🔢

Copy the full MPN

Do not BOM only "STM32F301" — include the full suffix (e.g. K6U7TR). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the STM32F301 product family.

STM32F301 is an entry-level mixed-signal microcontroller series from STMicroelectronics within the STM32F3 family. It uses an Arm Cortex-M4 core with FPU and DSP instructions and runs up to 72 MHz.
STM32F301 devices provide up to 64 KB of Flash memory, depending on the exact part number.
The STM32F301 series includes 16 KB of SRAM.
STM32F301 MCUs operate from 2.0 V to 3.6 V.
Yes. STM32F301 uses an Arm Cortex-M4 core with FPU and DSP instructions, which helps with signal-processing and control applications.
STM32F301 devices may include fast 12-bit ADCs, 12-bit DACs, comparators and an operational amplifier with programmable gain. The exact peripheral availability should be checked against the selected part number datasheet.
The main difference is usually Flash density. STM32F301C6 variants are commonly associated with lower Flash density, while STM32F301C8 variants provide higher Flash density within the STM32F301 family. Always confirm package, temperature grade and orderable suffix before replacement.
STM32F301 is positioned as an entry-level STM32F3 mixed-signal MCU line, while STM32F303 devices generally offer a richer analog and control peripheral set within the STM32F3 family. For replacement or upgrade, compare pinout, memory size, ADC/DAC/COMP/OPAMP resources, timers and firmware compatibility.
Yes. STM32F301 includes fast motor-control timer features and mixed-signal peripherals, making it suitable for compact motor-control and embedded control applications.
No. Pin compatibility depends on the exact package and suffix, such as LQFP, UFQFPN or WLCSP variants. Before replacing one STM32F301 part with another, verify the package, pinout, Flash size, temperature grade and peripheral availability.
