Product details
Overview
STM32F302VCT6TR 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 (17-channel, 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 Full-Speed, five USARTs, three SPIs (two with I2S), two I²C interfaces, RTC with alarm, and capacitive touch sensing - deployed in industrial motor control and precision analog signal conditioning systems.
For engineers reviewing the STM32F302VCT6TR datasheet, STM32F302VCT6TR pinout, STM32F302VCT6TR application, or STM32F302VCT6TR equivalent, key selection criteria include its integrated analog front-end (dual ADCs + DAC + PGAs + COMP), 64-pin LQFP package with 5 V-tolerant I/Os, CAN+USB connectivity, and support for real-time control loops requiring sub-microsecond timing resolution and mixed-signal co-processing.
Technical Context
The STM32F302VCT6TR implements a tightly coupled Cortex-M4 core with hardware FPU and MPU, enabling deterministic DSP operations and memory-protected multitasking. Its analog subsystem includes two independent 12-bit ADCs with selectable 6/8/10/12-bit resolution, differential input capability, and dedicated 2–3.6 V analog supply - synchronized via shared trigger sources for phase-aligned sampling.
Digital peripherals are orchestrated through an interconnect matrix supporting concurrent high-bandwidth transfers: a 12-channel DMA controller routes ADC results to memory while timers (including advanced-control TIM1 with deadtime generation) drive PWM outputs for 3-phase motor gate drivers. The embedded CAN 2.0B controller operates independently of CPU load, with message filtering and FIFO buffering for robust fieldbus communication.

FAQ
What is the maximum operating frequency and supported voltage range for STM32F302VCT6TR?
The STM32F302VCT6TR operates at up to 72 MHz using its internal PLL, with VDD and VDDA supply voltage ranges specified from 2.0 V to 3.6 V. The device includes a programmable voltage detector (PVD) that monitors VDD and can generate interrupts or reset events when voltage falls below a user-configurable threshold within this range.
Does STM32F302VCT6TR support hardware cryptographic acceleration?
No, the STM32F302VCT6TR does not include dedicated hardware cryptographic accelerators such as AES, SHA, or PKA engines. It relies on software libraries (e.g., Mbed TLS) for encryption tasks. For hardware-accelerated crypto, ST's STM32L4+, STM32H7, or STM32U5 series are recommended alternatives.
How many analog-to-digital converters does STM32F302VCT6TR integrate, and what are their key electrical specs?
The STM32F302VCT6TR integrates two independent 12-bit ADCs, each supporting selectable resolution (6/8/10/12 bits), conversion times as fast as 0.20 µs, and up to 17 input channels. They operate with a separate 2.0–3.6 V analog supply (VDDA), support single-ended and differential inputs, and feature built-in temperature sensor and VREFINT references.
Is STM32F302VCT6TR qualified for automotive applications?
No, the STM32F302VCT6TR is rated for industrial temperature range (–40°C to +85°C) and is not AEC-Q100 qualified. For automotive body electronics or infotainment applications, ST recommends the pin-compatible STM32F302x8 automotive-grade variants (e.g., STM32F302V8T6) which undergo extended reliability testing and meet AEC-Q100 Grade 2 requirements.
