Product details
Overview
STM32F301C8T6 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 64 KB Flash, 16 KB SRAM, and integrated analog peripherals including 12-bit ADC (0.20 μs conversion), 12-bit DAC, three rail-to-rail comparators, and one operational amplifier-designed for real-time motor control, sensor signal conditioning, and capacitive touch interfaces in industrial and consumer equipment.
For engineers reviewing the STM32F301C8T6 datasheet, STM32F301C8T6 pinout, STM32F301C8T6 application, or STM32F301C8T6 equivalent, key selection criteria include its 72 MHz CPU clock, 51 fast I/Os (including 18 capacitive sensing channels), 2.0–3.6 V supply range, and LQFP48 package compatibility with mixed-signal embedded designs requiring precision analog front-ends and deterministic real-time execution.
Technical Context
The STM32F301C8T6 implements an Arm Cortex-M4 core with single-cycle multiply and hardware divide, supporting DSP instructions for efficient filtering and control loop computation. Its interconnect matrix enables concurrent peripheral access without bus contention, while the programmable voltage detector (PVD) and multiple low-power modes (Sleep/Stop/Standby) support energy-sensitive applications.
Analog subsystem integration includes independent analog supplies (VDDA 2.0–3.6 V, VREF+ 2.4–3.6 V), dedicated 12-bit ADC with selectable resolution (6/8/10/12 bits) and differential mode, and an op-amp configurable as a programmable gain amplifier (PGA) with all terminals accessible-enabling direct sensor interface without external signal conditioning.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F303C8T6 | Includes additional peripherals: 2× 12-bit ADCs, 2× DACs, USB 2.0 FS, and enhanced op-amp features (rail-to-rail output, higher GBW). | Required for USB-connected sensor hubs or dual-channel analog acquisition where STM32F301C8T6 lacks sufficient ADC/DAC resources. | Select when USB connectivity or redundant analog channels are mandatory; otherwise, STM32F301C8T6 offers lower cost and identical core/performance for single-channel use cases. |
| STM32G431CBT6 | Higher CPU frequency (170 MHz), enhanced analog features (2× fast comparators with window mode, 3× op-amps), and improved ADC linearity (±0.5 LSB INL vs. ±1 LSB). | Suitable for next-generation motor drives requiring faster loop rates or tighter analog accuracy, but introduces migration effort due to different register map and HAL library version. | Choose for new designs targeting higher performance margins or future-proofing; avoid for drop-in replacement due to non-identical pinout and peripheral register layout. |
Compared with STM32F303C8T6, the STM32F301C8T6 trades USB and dual ADC for lower BOM cost and simpler qualification; versus STM32G431CBT6, it offers proven industrial reliability and mature toolchain support at the expense of peak analog precision and clock speed.

FAQ
What is the maximum operating frequency and supported voltage range for STM32F301C8T6?
The STM32F301C8T6 operates at a maximum CPU frequency of 72 MHz and supports a VDD supply range of 2.0 V to 3.6 V. Its VDDA analog supply must be within 2.0 V to 3.6 V, while the DAC analog supply (VREF+) requires 2.4 V to 3.6 V. These ranges are validated across the industrial temperature range (–40°C to +85°C) per DS9895 Rev 8.
Does STM32F301C8T6 support hardware-accelerated cryptographic functions?
No, the STM32F301C8T6 does not include hardware cryptographic accelerators such as AES, SHA, or PKA engines. It relies on software libraries for encryption tasks. For secure boot or data confidentiality, external secure elements or higher-series STM32 variants (e.g., STM32L5 or STM32H5) with TrustZone and crypto co-processors are required.
Can the integrated op-amp be used as a standalone instrumentation amplifier?
No-the single op-amp in STM32F301C8T6 supports PGA mode with external feedback but lacks the matched resistor network and dual-input topology required for true instrumentation amplifier behavior. It can be configured as a non-inverting amplifier or transimpedance amplifier, but differential gain with common-mode rejection requires external components or a dedicated IA IC.
What debug interfaces are supported, and is SWD pin-compatible with other STM32F3 devices?
The STM32F301C8T6 supports Serial Wire Debug (SWD) and JTAG via the SWJ-DP interface using SWCLK, SWDIO, and NRST pins. SWD pinout is consistent across STM32F3x6/x8 devices in LQFP48 packages, enabling shared debug probe configurations-but firmware initialization sequences and memory maps differ between sub-families, requiring toolchain-specific configuration.
