Product details
Overview
STM32F301C6T6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 32 KB Flash, 16 KB SRAM, integrated 12-bit DAC, three rail-to-rail comparators, and one programmable-gain operational amplifier. It operates from 2.0–3.6 V, supports up to 72 MHz CPU frequency, and targets analog-intensive embedded control applications such as motor drive feedback loops and sensor signal conditioning.
For engineers reviewing the STM32F301C6T6TR datasheet, STM32F301C6T6TR pinout, STM32F301C6T6TR application, or STM32F301C6T6TR equivalent, this page delivers verified technical context, validated pin functions, real-world use cases in analog-sensing systems, and confirmed alternative MCU options with documented functional trade-offs.
Technical Context
The device integrates an Arm Cortex-M4 core with single-cycle multiply and hardware divide, enabling deterministic DSP operations for real-time control. Its analog subsystem includes a 12-bit DAC (2.4–3.6 V analog supply), three ultra-fast comparators (2.0–3.6 V), and one op-amp configurable in PGA mode with all terminals accessible - all sharing independent analog power domains.
It features a 48-pin LQFP package with 39 GPIOs (5 V-tolerant on select pins), a 7-channel DMA controller, and dedicated peripherals including one 32-bit timer with quadrature encoder input, one advanced-control 16-bit timer with deadtime generation, and capacitive touch sensing supporting up to 18 channels - optimized for compact industrial HMI and motor control edge nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M4 with FPU, 72 MHz max - enables real-time DSP tasks like PID loop execution in <1 µs. |
| Flash / SRAM | 32 KB Flash, 16 KB SRAM - sufficient for closed-loop motor control firmware with floating-point math and calibration tables. |
| Analog Peripherals | 1×12-bit DAC (2.4–3.6 V), 3× comparators, 1× PGA-capable op-amp - supports precision analog front-end design without external components. |
| ADC | 1×12-bit ADC, 15-channel, 0.20 µs conversion - captures fast transients in current sensing or voltage monitoring circuits. |
| Operating Voltage | 2.0–3.6 V VDD/VDDA - compatible with standard 3.3 V industrial logic and analog rails; VDDA separation prevents digital noise coupling. |
| Package | LQFP48 (7 × 7 mm) - surface-mount footprint suitable for automated assembly and thermal management in compact PCB layouts. |

Pinout & Package
LQFP48 (7 × 7 mm, 0.5 mm pitch) package with exposed thermal pad; 48-pin square-outline leaded plastic package compliant with JEDEC MO-220.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Digital power supply and ground | Primary 2.0–3.6 V digital domain; decoupling required within 10 mm of pins for stable core operation. |
| VDDA, VSSA | Analog power supply and ground | Independent 2.0–3.6 V analog rail; must be filtered separately to preserve ADC/DAC/OPAMP accuracy. |

FAQ
What is the maximum operating frequency of the STM32F301C6T6TR?
The STM32F301C6T6TR achieves a maximum CPU clock frequency of 72 MHz using its internal PLL, driven by either the 4–32 MHz HSE crystal oscillator or the 8 MHz HSI RC oscillator with x9 multiplication. This frequency is sustained across the full –40°C to +85°C industrial temperature range with VDD ≥ 2.7 V.
Does the STM32F301C6T6TR support hardware-based floating-point operations?
Yes, the STM32F301C6T6TR integrates a single-precision Arm Cortex-M4 FPU, enabling hardware-accelerated IEEE 754-compliant floating-point arithmetic. This eliminates software emulation overhead, reducing execution time for trigonometric, logarithmic, and PID computations by up to 70% compared to integer-only implementations.
Can the integrated op-amp be used in standalone mode without external components?
Yes, the OPAMP1 module supports standalone PGA configuration with gains of 1, 2, 4, 8, 16, or 40× using only internal resistors. All op-amp terminals (non-inverting input, inverting input, output, and VOUT) are routed to GPIO pins - enabling direct connection to shunt resistors or sensors without external feedback networks.
What debug interfaces are supported, and are they available in production firmware?
The STM32F301C6T6TR supports Serial Wire Debug (SWD) and JTAG via dedicated SWCLK/SWDIO and TCK/TMS/TDO/TDI pins. These interfaces remain fully functional in production firmware unless explicitly disabled by option byte configuration; SWD is recommended for minimal pin count and reliable in-circuit debugging.
