Product details
Overview
STM32F302R6T6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 64 KB Flash, 16 KB SRAM, integrated USB 2.0 full-speed interface, CAN 2.0B controller, and analog peripherals including 12-bit DAC, rail-to-rail comparators, and programmable-gain operational amplifier. It operates from 2.0–3.6 V and targets motor control, industrial sensing, and USB-connected embedded systems.
For engineers reviewing the STM32F302R6T6TR datasheet, STM32F302R6T6TR pinout, STM32F302R6T6TR application, or STM32F302R6T6TR equivalent, key selection criteria include its 72 MHz CPU with hardware DSP instructions, dual ADC capability (15-channel, 0.20 µs conversion), 18-capacitive-touch-channel TSC, and LQFP64 package with 51 fast I/Os - all critical for real-time mixed-signal designs.
Technical Context
The device integrates an Arm Cortex-M4 core with single-cycle multiply and hardware divide, coupled to a dedicated interconnect matrix enabling concurrent peripheral access without bus contention. Its analog subsystem includes three independent comparators, one PGA-capable op-amp with external terminal access, and a temperature sensor referenced to internal VREFINT.
Clock management supports four oscillators (HSE, LSE, HSI, LSI) and a PLL with configurable input/output dividers; the RTC features calendar mode, alarm, and periodic wakeup from Stop/Standby modes using the 32 kHz LSE oscillator with calibration support.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F303R8T6 | 64 KB Flash, 16 KB SRAM, adds 2nd 12-bit DAC channel and enhanced ADC resolution (up to 16-bit via oversampling). | Required for dual-output analog control (e.g., dual-motor systems) or higher-precision sensor digitization. | Select when additional DAC channel or oversampled ADC accuracy is mandatory; otherwise, STM32F302R6T6TR offers lower cost and identical footprint. |
| STM32G431RBT6 | Same LQFP64 package, 128 KB Flash, 32 KB SRAM, higher CPU clock (170 MHz), enhanced analog (2x OPAMP, 2x DAC, 2x ADC), no CAN. | Suitable for compute-intensive motor control or AI-edge inference where CAN is not required and USB + multiple analog channels are prioritized. | Choose for performance headroom and future-proofing; avoid if CAN bus integration or cost sensitivity is primary. |
Compared with STM32F303R8T6, the STM32F302R6T6TR trades one DAC channel and oversampling capability for lower unit cost and identical pin compatibility; versus STM32G431RBT6, it retains CAN 2.0B at lower clock speed and memory - making it optimal for cost-constrained, CAN-dependent industrial nodes.

FAQ
What is the maximum operating frequency and does it require external clock circuitry?
The STM32F302R6T6TR runs at up to 72 MHz using its internal 8 MHz RC oscillator multiplied by the PLL, eliminating need for external crystal in basic applications. An external 4–32 MHz HSE crystal is optional for higher timing accuracy, especially for USB or RTC synchronization.
Does this MCU support hardware-based USB device functionality without external PHY?
Yes - it integrates a full-speed USB 2.0 device transceiver with internal pull-up resistors and descriptor handling logic. PA11 (DM) and PA12 (DP) are dedicated pins; no external PHY or level shifter is required for standard USB device operation.
How many analog comparators and op-amps are included, and are their inputs/outputs accessible externally?
It includes three rail-to-rail ultra-fast comparators and one operational amplifier configurable as a programmable-gain amplifier (PGA). All comparator outputs and OPAMP inputs/outputs (VIN+, VIN−, VOUT) are routed to dedicated GPIO pins (e.g., PA4–PA7), enabling direct external connection without internal routing constraints.
Is the LQFP64 package RoHS-compliant and what is its thermal performance rating?
Yes - the LQFP64 package (part number suffix 'T6') is RoHS-compliant and halogen-free. Its thermal resistance θJA is 46 °C/W (JEDEC Std 51-7, 4-layer board), supporting continuous operation up to 105 °C ambient when properly heatsinked via the exposed thermal pad.
