Product details
Overview
STM32F301C6T7 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 32 KB Flash, 16 KB SRAM, and integrated analog peripherals including 1×12-bit DAC, 1×rail-to-rail op-amp (PGA-capable), 3×fast comparators, and 1×0.20 μs ADC (12/10/8/6-bit selectable). It operates from 2.0–3.6 V and targets sensor signal conditioning and motor control in compact industrial HMI modules.
For engineers reviewing the STM32F301C6T7 datasheet, STM32F301C6T7 pinout, STM32F301C6T7 application, or STM32F301C6T7 equivalent, key selection criteria include its 48-pin LQFP package, 72 MHz max CPU frequency, analog supply flexibility (VDDA 2.0–3.6 V, VREF+ 2.4–3.6 V), and integrated capacitive touch sensing (up to 18 channels) for cost-sensitive embedded front panels.
Technical Context
This MCU implements a tightly coupled Cortex-M4 core with single-cycle multiply and hardware divide, supporting DSP instructions for real-time filtering and motor phase computation. Its analog subsystem features independent power domains: VDDA supplies the ADC, DAC, COMP, and OPAMP, while VREF+ (2.4–3.6 V) feeds the DAC reference and OPAMP non-inverting input.
The interconnect matrix enables concurrent peripheral access without bus contention, and the 9-channel DMA controller supports zero-CPU-overhead data movement between ADC, DAC, SPI, and memory. The advanced-control timer (TIM1) delivers 6-channel PWM with programmable deadtime-critical for 3-phase inverter gate driving.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M4 with FPU, 72 MHz max - enables real-time floating-point math for sensor fusion or PID loop execution in <10 μs. |
| Memory | 32 KB Flash / 16 KB SRAM - sufficient for closed-loop motor control firmware with dual-bank boot and runtime parameter storage. |
| ADC | 12-bit, 0.20 μs conversion, 15-channel, 0–3.6 V range - supports simultaneous sampling of current/voltage feedback in BLDC drives. |
| DAC | 1×12-bit, rail-to-rail output, 2.4–3.6 V analog supply - generates precise bias voltages for op-amp instrumentation circuits. |
| Op-Amp | Rail-to-rail, PGA mode, all terminals accessible - allows configurable gain (1–16×) for amplifying low-level thermistor or strain gauge signals. |
| Comparators | 3×fast ultra-low propagation delay (<150 ns), 2.0–3.6 V supply - used for overcurrent trip detection with sub-microsecond response. |
| Capacitive Sensing | Up to 18 channels, dedicated TSC peripheral - enables robust touchkey interfaces without external ICs in space-constrained enclosures. |
Pinout & Package
LQFP48 (7 × 7 mm, 0.5 mm pitch) package with exposed thermal pad; 48 pins arranged in single-row perimeter layout, compatible with standard reflow profiles and manual soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Core power supply pair | Supplies 2.0–3.6 V to digital logic; requires local 100 nF + 4.7 μF decoupling per VDD pin. |
| VDDA, VSSA | Analog domain supply pair | Isolates noise-sensitive ADC/DAC/OPAMP circuitry; must be filtered separately from VDD. |
| VREF+ | DAC and OPAMP reference input | Accepts 2.4–3.6 V external reference or internal VDDA; sets full-scale DAC output and op-amp gain accuracy. |
| PA0–PA15, PB0–PB15, PC0–PC15, PD0–PD2 | General-purpose I/O | 51 total GPIOs; up to 40 support 5 V-tolerant inputs - simplifies interface with legacy 5 V sensors or logic. |
| PA1, PA2, PA3, PA4, PA5, PA6, PA7 | Analog input channels (ADC1_INx) | Map directly to 12-bit ADC; support differential mode for noise-rejecting measurements on motor current shunts. |
| PA4 | DAC output (DAC_OUT1) | Direct rail-to-rail voltage source; usable as programmable bias for comparator reference or op-amp feedback. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable voltage detector (PVD) | Configurable threshold (2.2–2.9 V) triggers interrupt or reset - prevents erratic operation during brown-out in battery-powered HMIs. |
| Temperature sensor | Calibrated ±1.5°C accuracy across –40 to +85°C - enables ambient temperature compensation for analog sensor readings. |
| Independent watchdog (IWDG) | 40 kHz LSI clock source, timeout from 4 ms to 32 s - ensures fail-safe recovery in unattended industrial controllers. |
| RTC with alarm & wakeup | 32.768 kHz LSE oscillator support, calendar function - maintains timekeeping in Stop mode with <1 μA VBAT current. |
| SWD debug interface | 2-pin Serial Wire Debug (SWCLK/SWDIO) - enables full JTAG-equivalent debugging without sacrificing GPIO count. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F302C8T7 | 64 KB Flash, same peripherals but adds USB 2.0 FS interface and CRC accelerator. | Required when host-side USB device connectivity (e.g., HID keyboard emulation) is needed. | Select if USB device stack integration is mandatory; otherwise STM32F301C6T7 offers lower cost and identical analog performance. |
| STM32F072CBT6 | Cortex-M0+, 128 KB Flash, no FPU, no op-amp, only 1 comparator, slower 12-bit ADC (1.2 μs). | Suitable for simpler control tasks without real-time analog processing or motor phase computation. | Choose for cost-sensitive applications where DSP math or high-speed analog comparison is unnecessary. |
Compared with STM32F302C8T7, the STM32F301C6T7 trades USB capability for lower price and identical analog subsystem fidelity; versus STM32F072CBT6, it delivers 2.5× faster ADC, integrated op-amp, and FPU-enabled control loops - justifying its use in precision analog-intensive designs.

FAQ
What is the maximum operating frequency and supported voltage range for STM32F301C6T7?
The STM32F301C6T7 operates at up to 72 MHz using its internal PLL and supports a VDD supply range of 2.0–3.6 V. Its VDDA and VREF+ analog supplies accept 2.0–3.6 V and 2.4–3.6 V respectively, enabling stable analog performance across the full digital operating range without external regulators.
Does STM32F301C6T7 support hardware-accelerated cryptographic functions?
No, the STM32F301C6T7 does not include a hardware crypto engine or TRNG. It lacks AES, DES, SHA, or PKA accelerators. Security relies on software libraries; for hardware crypto, consider STM32L4 or STM32H7 series devices with dedicated cryptographic peripherals.
Can the integrated op-amp be configured as a programmable-gain amplifier (PGA)?
Yes, the single rail-to-rail op-amp supports PGA mode with gain settings of 1, 2, 3, 4, 8, 12, or 16× via internal resistor network configuration. All op-amp terminals (non-inverting input, inverting input, output) are accessible on dedicated pins - enabling external feedback or sensor connection without signal routing through GPIOs.
What debug interfaces are available and how many pins do they require?
The STM32F301C6T7 supports Serial Wire Debug (SWD) using two pins - SWCLK and SWDIO - providing full debugging capability (breakpoints, register access, flash programming) with minimal pin overhead. JTAG is also supported but requires five pins; SWD is recommended for space-constrained LQFP48 layouts.
