Product details
Overview
STM32F302CCT6TR from STMicroelectronics is an Arm® Cortex®-M4 32-bit microcontroller with FPU, operating up to 72 MHz, featuring 256 KB Flash, 40 KB SRAM (16 KB with HW parity), dual 12-bit ADCs (0.20 µs conversion), one 12-bit DAC, four rail-to-rail comparators, and two programmable-gain operational amplifiers. It integrates CAN 2.0B, USB 2.0 FS, five USARTs, three SPIs/I2S, two I2C, RTC with alarm, and capacitive touch sensing - deployed in motor control, digital power supplies, and industrial sensor interfaces.
For engineers reviewing the STM32F302CCT6TR datasheet, STM32F302CCT6TR pinout, STM32F302CCT6TR application, or STM32F302CCT6TR equivalent, key selection criteria include analog peripheral supply ranges (VDDA: 2.0–3.6 V; VREFOPAMP: 2.4–3.6 V), 5 V-tolerant GPIO count (up to 87), LQFP48 package footprint compatibility, and integrated analog signal chain capability for closed-loop control.
Technical Context
The device implements a tightly coupled Cortex-M4 core with single-cycle multiply, hardware divide, DSP extensions, and MPU-enabling deterministic real-time execution in safety-aware firmware. Its analog subsystem includes two independent ADCs with selectable 6/8/10/12-bit resolution, differential input support, and dedicated analog supply domain (2.0–3.6 V).
Digital peripherals are orchestrated via an interconnect matrix supporting concurrent high-bandwidth transfers; the advanced-control timer (TIM1) delivers 6-channel PWM with programmable deadtime and emergency stop-critical for three-phase inverter gate driving in BLDC motor control systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F303CCT6 | Includes embedded bootloader, higher ADC accuracy (±1 LSB INL), no TSC | Better suited for metrology-grade measurement where ADC linearity is critical | Select when absolute analog measurement fidelity outweighs capacitive touch capability |
| STM32G431CBT6 | Higher CPU frequency (170 MHz), enhanced analog (2x faster ADC, 2x DAC), no CAN | Optimized for high-speed digital power control with complex control loops | Choose for next-gen SMPS designs requiring >100 kHz PWM update rates |
Compared with STM32F303CCT6, the STM32F302CCT6TR trades minor ADC linearity for integrated touch sensing; versus STM32G431CBT6, it retains CAN and lowers cost while delivering sufficient performance for mid-tier motor control and industrial I/O.

FAQ
What is the maximum operating frequency and supported clock sources?
The STM32F302CCT6TR operates at up to 72 MHz using its internal 8 MHz RC oscillator with PLL multiplication, or external crystal sources (4–32 MHz HSE or 32.768 kHz LSE). The PLL supports integer and fractional multiplication factors, enabling precise clock generation for USB, CAN, and ADC sampling timing.
Does this MCU support hardware encryption or secure boot features?
No - the STM32F302CCT6TR does not include hardware cryptographic accelerators (AES, SHA, PKA) or secure boot ROM. It relies on software-based security measures and external secure elements for authentication or firmware signing; functional safety compliance (e.g., IEC 61508 SIL2) is achievable via software libraries and diagnostic routines.
What are the analog supply requirements for the DAC and op-amps?
The DAC requires VDDA = 2.4–3.6 V; op-amps require VDDA = 2.4–3.6 V and support rail-to-rail output. Both share the same analog supply domain, which must be filtered separately from digital VDD to maintain SNR. VREFOPAMP is internally derived and not user-accessible.
Is the LQFP48 package RoHS-compliant and lead-free?
Yes - the STM32F302CCT6TR in LQFP48 packaging is RoHS-compliant and lead-free per STMicroelectronics' product change notification PCN 18-0125, with matte tin (Sn) termination and JEDEC J-STD-020 moisture sensitivity level MSL3.
