STMicroelectronics STM32F302VCT7TR

Overview

STM32F302VCT7TR from STMicroelectronics is an Arm® Cortex®-M4 32-bit MCU 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 FS, five USARTs, three SPIs (two with I2S), two I2C Fast Mode Plus interfaces, and capacitive touch sensing - deployed in motor control, digital power supplies, and industrial sensor nodes.

For engineers reviewing the STM32F302VCT7TR datasheet, STM32F302VCT7TR pinout, STM32F302VCT7TR application, or STM32F302VCT7TR equivalent, key selection criteria include its analog integration (PGA + DAC + COMP), 5 V-tolerant GPIOs, LQFP100 package compatibility, and support for real-time control via advanced timers with deadtime generation and emergency stop.

Technical Context

The STM32F302VCT7TR implements a tightly coupled Cortex-M4 core with hardware FPU and memory protection unit (MPU), enabling deterministic execution of DSP-intensive control algorithms. Its interconnect matrix decouples peripheral bus arbitration from CPU access, reducing latency for time-critical analog and timer operations.

Analog subsystem coherency is maintained through shared voltage domains: VDDA (2.0–3.6 V) powers both ADCs and comparators, while dedicated VREFOPAMP (2.4–3.6 V) enables stable PGA reference; the 12-bit DAC uses separate analog supply (2.4–3.6 V) and is driven by TIM6 for precise waveform generation.

FAQ

What is the maximum operating temperature range for STM32F302VCT7TR?

The STM32F302VCT7TR is rated for industrial temperature range: –40 °C to +85 °C. This is confirmed in Section 6.3.1 of DS9911 Rev 9, specifying ambient operating conditions and thermal derating curves up to 105 °C junction temperature under defined power dissipation limits.

Does STM32F302VCT7TR support USB device enumeration without external components?

Yes - it integrates a full-speed USB 2.0 transceiver with internal pull-up resistors and SOF generation. The USB_DM/DP pins connect directly to the connector; no external PHY or termination resistors are required for basic CDC or HID class operation per Section 3.24 and Table 67 of the datasheet.

How many independent PWM outputs can be generated simultaneously on this MCU?

Up to 12 independent PWM outputs are supported: TIM1 provides 6 complementary channels, TIM2/TIM3/TIM4 each offer up to 4 channels, and TIM15/TIM16/TIM17 add further OC/PWM capability. Total concurrent outputs depend on pin remapping and clock configuration, but hardware supports ≥12 non-overlapping signals per Section 3.17.

Is the internal 40 kHz LSI oscillator calibrated at factory?

No - the 40 kHz LSI oscillator is uncalibrated and exhibits ±40% variation over temperature and voltage. For time-critical functions like RTC calibration or low-power wakeup timing, designers must use the 32.768 kHz LSE crystal or perform runtime calibration against HSE or USB SOF per Section 6.3.8 and AN2867.
