STMicroelectronics STM32F302VCT7

Overview

STM32F302VCT7 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, operating at up to 72 MHz, featuring 256 KB Flash, 40 KB SRAM (with HW parity on first 16 KB), dual 12-bit ADCs (0.20 µs conversion, 17-channel), one 12-bit DAC, four rail-to-rail comparators, and two programmable-gain operational amplifiers - deployed in industrial motor control, digital power supplies, and analog-sensor signal conditioning systems.

For engineers reviewing the STM32F302VCT7 datasheet, STM32F302VCT7 pinout, STM32F302VCT7 application, or STM32F302VCT7 equivalent, key selection criteria include its integrated analog front-end (2× PGA, 4× COMP, 2× ADC), CAN 2.0B interface, capacitive touch sensing (24 channels), and support for multiple low-power modes (Stop/Standby) with RTC and VBAT backup.

Technical Context

The STM32F302VCT7 integrates an Arm Cortex-M4 core with hardware FPU and memory protection unit (MPU), enabling deterministic real-time control and secure memory partitioning. Its interconnect matrix enables concurrent peripheral access without bus contention, critical for time-sensitive analog-digital co-processing.

Analog subsystem design centers on independent supply domains: VDDA (2.0–3.6 V) powers ADCs, DAC, comparators, and OPAMPs; dedicated VREFOPAMP and VREFINT references ensure precision across 12-bit conversions and PGA gain stages. The device supports simultaneous sampling across both ADCs and synchronized triggering with advanced timers (TIM1/TIM8).

FAQ

What is the maximum operating frequency and supported voltage range?

The STM32F302VCT7 operates at up to 72 MHz using its internal PLL. Its VDD and VDDA supply range is 2.0 V to 3.6 V, with separate analog and digital power domains. The device includes a programmable voltage detector (PVD) and supports brown-out reset down to 1.65 V, ensuring reliable operation across industrial voltage tolerances.

Does it support hardware CRC and memory protection?

Yes - the STM32F302VCT7 includes a dedicated CRC calculation unit compliant with IEEE-802.3 for fast checksum generation on data buffers or firmware images. It also implements a full Memory Protection Unit (MPU) supporting eight regions with configurable attributes (read/write/execute permissions, shareability, cacheability), enabling RTOS-based secure task isolation.

How many analog peripherals are integrated and what are their key specs?

The device integrates two 12-bit ADCs (0.20 µs conversion, 17-channel total), one 12-bit DAC (2.4–3.6 V analog supply), four rail-to-rail comparators (with internal hysteresis), and two operational amplifiers configurable as PGAs (gain 1–100×). All analog blocks share independent VDDA/VSSA and support external reference inputs for precision measurement.

Is USB and CAN supported simultaneously with full functionality?

Yes - the STM32F302VCT7 features a full-speed USB 2.0 interface (12 Mbit/s) and a CAN 2.0B controller on separate physical layers. Both operate concurrently without resource conflict; USB uses dedicated DP/DM pins, while CAN uses PD0/PD1. DMA and NVIC priority configuration allow deterministic handling of both high-bandwidth USB transfers and time-critical CAN messages.
