STMicroelectronics STM32F302VDT6TR

Overview

STM32F302VDT6TR from STMicroelectronics is a 32-bit ARM® Cortex®-M4 microcontroller with FPU, operating at up to 72 MHz, featuring 384 KB Flash, 64 KB SRAM (with HW parity on first 32 KB), dual 12-bit ADCs (18-channel, 0.20 µs conversion), one 12-bit DAC, four rail-to-rail comparators, and two operational amplifiers usable in PGA mode - deployed in industrial motor control and analog-sensor signal conditioning systems.

For engineers reviewing the STM32F302VDT6TR datasheet, STM32F302VDT6TR pinout, STM32F302VDT6TR application, or STM32F302VDT6TR equivalent, key selection criteria include its integrated analog front-end (dual ADCs + DAC + OPAMPs + COMP), flexible clocking (HSE/LSE/HSI/LSI + PLL), FSMC interface for external memory expansion, and CAN 2.0B support for industrial networking.

Technical Context

The device implements an ARM Cortex-M4 core with hardware FPU, single-cycle MAC, and DSP instructions, paired with a Memory Protection Unit (MPU) for real-time OS partitioning. Its analog subsystem includes two independent 12-bit ADCs with selectable resolution (6/8/10/12-bit), shared 0–3.6 V input range, and dedicated analog supply (V_DDA: 2.0–3.6 V).

Clock architecture supports multiple sources: 4–32 MHz HSE crystal, 32.768 kHz LSE for RTC, 8 MHz HSI with x16 PLL, and 40 kHz LSI. The interconnect matrix enables concurrent peripheral access without bus contention, while the FSMC provides configurable timing for NOR/PSRAM/NAND and PC Card interfaces.

FAQ

What is the maximum operating frequency and supported voltage range?

The STM32F302VDT6TR operates at up to 72 MHz with an ARM Cortex-M4 core and supports a V_DD/V_DDA supply range of 2.0 V to 3.6 V. It includes a programmable voltage detector (PVD) that monitors V_DD and triggers interrupts at user-configurable thresholds, ensuring reliable operation during voltage fluctuations common in industrial environments.

Does this MCU support hardware-accelerated cryptography?

No, the STM32F302VDT6TR does not include hardware cryptographic accelerators such as AES or SHA engines. It relies on software libraries for encryption tasks. For applications requiring hardware crypto, consider the STM32F303 or STM32L4 series, which integrate AES-128 accelerators and true random number generators.

How many analog-to-digital converters are integrated, and what are their key capabilities?

This MCU integrates two independent 12-bit ADCs, each supporting up to 18 input channels, selectable resolution (6/8/10/12-bit), and 0.20 µs conversion time. They share a 0–3.6 V input range and use a dedicated analog supply (V_DDA: 2.0–3.6 V). Synchronization modes allow simultaneous sampling - essential for three-phase motor current measurement and differential sensor readings.

Is the LQFP64 package RoHS-compliant and suitable for lead-free reflow?

Yes, the STM32F302VDT6TR in LQFP64 package is RoHS-compliant and qualified for lead-free reflow soldering per JEDEC J-STD-020. Its maximum peak reflow temperature is 260 °C, and the package features an exposed thermal pad for improved heat dissipation in continuous-duty industrial applications.
