Product details
Overview
STM32F301C6T6 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 32 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 programmable-gain operational amplifier. It operates from 2.0–3.6 V and targets sensor signal conditioning and motor control in compact industrial and consumer devices.
For engineers reviewing the STM32F301C6T6 datasheet, STM32F301C6T6 pinout, STM32F301C6T6 application, or STM32F301C6T6 equivalent, key selection criteria include its 48-pin LQFP package, 72 MHz CPU clock, analog supply flexibility (VDDA 2.0–3.6 V, VREF+ 2.4–3.6 V), and embedded capacitive touch sensing support for human interface designs.
Technical Context
The STM32F301C6T6 implements a tightly coupled Cortex-M4 core with single-cycle MAC and hardware divide, enabling real-time DSP operations without external co-processing. Its interconnect matrix routes up to 51 GPIOs-including 18 capacitive sensing channels-to multiple peripherals including three I²C interfaces (Fast-mode Plus), three USARTs (one with ISO 7816), and two SPI/I²S controllers.
Analog subsystem integration includes independent voltage domains: VDDA powers the 12-bit ADC (15-channel, selectable 6/8/10/12-bit resolution) and temperature sensor; VREF+ supplies the 12-bit DAC and op-amp; COMP analog inputs accept 0–VDDA range. All analog blocks share common reference calibration (VREFINT) and support differential measurement modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M4 with FPU, 72 MHz max - enables real-time control loops and floating-point math in motor/sensor firmware without external DSP. |
| Memory | 32 KB Flash + 16 KB SRAM - sufficient for closed-loop control algorithms with integrated safety checks and field-upgradable firmware. |
| ADC | 12-bit, 0.20 μs conversion, 15 channels - supports simultaneous sampling of current/voltage/temperature in BLDC motor drives. |
| DAC | 1 × 12-bit channel, 2.4–3.6 V analog supply - generates precise bias voltages or analog setpoints for op-amp-based signal conditioning. |
| Op-Amp | 1 rail-to-rail PGA with all terminals accessible - configurable as transimpedance amplifier for photodiode sensors or active filter stage. |
| Comparator | 3 ultra-fast comparators, 2.0–3.6 V analog supply - provides hardware overcurrent/overvoltage protection with sub-100 ns response. |
| Package | LQFP48 (7 × 7 mm) - compatible with standard PCB assembly processes and offers full GPIO access for prototyping and production. |
Pinout & Package
LQFP48 package, 0.5 mm pitch, 7 × 7 mm body, exposed thermal pad (not electrically connected). Pin 1 marked by dot or notch; pins numbered counterclockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Main digital power supply | 2.0–3.6 V input; decoupling required per datasheet layout guidelines to ensure stable core operation at 72 MHz. |
| VDDA | Analog power supply | Independent 2.0–3.6 V domain for ADC/DAC/COMP/OPAMP; must be filtered separately from VDD to minimize noise coupling. |
| VREF+ | Analog reference positive | 2.4–3.6 V input for DAC and op-amp; internal VREFINT can be used if external reference not required. |
| PA0–PA15 | General-purpose I/O port A | Up to 15 pins support alternate functions including TIM2_CH1, ADC1_IN0, COMP1_OUT, TSC_G1_IO1–G1_IO4. |
| PB0–PB15 | General-purpose I/O port B | Includes TIM3_CH3, I2C1_SCL, USART1_TX, ADC1_IN8, TSC_G2_IO1–G2_IO4, and 5 V-tolerant capability on select pins. |
| PC13–PC15 | Low-power backup domain | RTC oscillator (LSE) and backup register access; retain state in Standby mode with VBAT applied. |
Key Features
| Feature | Design Value |
|---|---|
| Embedded Analog Subsystem | Single-chip integration of ADC, DAC, COMP, and OPAMP eliminates discrete signal chain components and reduces board area by >40%. |
| Capacitive Touch Sensing | 18-channel TSC supports self- and mutual-capacitance modes for robust touchkey, slider, and rotary encoder implementation without external IC. |
| Low-Power Operation | Stop mode current <1.3 μA (typ.) with RTC running - enables battery-powered sensor nodes with multi-year runtime on coin cells. |
| Robust Clock System | Four clock sources (HSE/LSE/HSI/LSI) with PLL and automatic clock switching - ensures reliable operation during crystal failure or voltage brownout. |
| Debug & Trace | Serial Wire Debug (SWD) interface with 4-pin footprint - enables full JTAG-level debugging without sacrificing GPIO count or board space. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F072CBT6 | ARM Cortex-M0, no FPU, 12-bit ADC only (1.0 μs), no DAC or op-amp - lower compute and analog capability. | Suitable for basic control tasks without sensor fusion or analog signal generation. | Select when cost sensitivity outweighs need for DSP acceleration or analog integration. |
| STM32F303CCT6 | Same package but 256 KB Flash, 48 KB SRAM, dual ADC, additional op-amp and comparator - higher resource headroom. | Required for complex motor control with dual-shunt FOC or multi-axis motion profiling. | Select when firmware size exceeds 32 KB or simultaneous analog acquisition from >15 channels is needed. |
Compared with STM32F301C6T6, the STM32F072CBT6 sacrifices FPU, DAC, and op-amp for lower BOM cost and power, while the STM32F303CCT6 adds memory and analog resources for scaling complexity-neither is pin-compatible, requiring PCB redesign.

FAQ
What is the maximum operating frequency of the STM32F301C6T6?
The STM32F301C6T6 achieves a maximum CPU clock of 72 MHz using its internal PLL driven by the 8 MHz HSI or external 4–32 MHz crystal. This frequency is sustained across the full industrial temperature range (–40°C to +85°C) when powered within the 2.0–3.6 V VDD specification and with proper decoupling.
Does the STM32F301C6T6 support hardware-accelerated cryptographic functions?
No. The STM32F301C6T6 does not include dedicated cryptographic accelerators (e.g., AES, SHA, PKA). It relies on software libraries for encryption; for hardware security, ST's STM32L4 or STM32H7 series with CryptoCell or HASH/AES peripherals are recommended alternatives.
Can the integrated op-amp be used in instrumentation amplifier configuration?
Yes-the single op-amp supports programmable gain amplifier (PGA) mode with external resistors, and its inputs are fully accessible. However, it lacks built-in matched resistor networks or dedicated INAMP topology; external precision resistors are required to achieve high CMRR in instrumentation amplifier configurations.
Is the STM32F301C6T6 qualified for automotive applications?
No. The STM32F301C6T6 is specified for industrial temperature range (–40°C to +85°C) and is not AEC-Q100 qualified. For automotive use, ST's STM32F302x8 or STM32G4 series with AEC-Q100 Grade 2 qualification and extended temperature support should be selected.
